The best biscuit joiner for most woodworking jobs is a plate joiner whose listing states the biscuit sizes you use, the fence angle range and whether a battery is needed. The seven plate joiners in this post include three cordless models and four corded ones. Three listings state a biscuit count, and one says biscuits are sold separately. Each listing states different figures, so we show what each one says and what it leaves out.

Quick answer

  • Cordless: the DEWALT DCW682B is the lightest stated option at 6 lb, and it is tool only. The Ecarke and Makita XJP03Z are the other cordless joiners in this set.
  • Biscuits in the box: the AOBEN title lists 110 biscuits (30 No. 0, 30 No. 10 and 50 No. 20), and the WOODSTARTER title lists 100.
  • Highest stated speed: the WOODSTARTER lists 12,000 RPM on an 8.5 amp corded motor.
  • Widest size claim: the DEWALT DW682K says its depth stops cover all common biscuit sizes. Most other listings name #0, #10 and #20.

The biscuit joiners we read

The table uses only the figures each listing states. A cell that reads not stated means the listing is silent on that point.

Listing Power Motor or speed stated Biscuit sizes stated Weight stated Included, as stated
DEWALT DW682K, 6.5 amp Corded, 120 volts 6.5 amp, 10,000 rpm Preset depth stops for all common biscuit sizes not stated not stated
AOBEN 8.5 amp plate joiner Corded 8.5A, 11,000 rpm #0, #10 and #20, plus an M manual setting 7.6 lbs 30 No. 0, 30 No. 10 and 50 No. 20 biscuits; dust bag
DEWALT DCW682B, 20V MAX XR Battery powered, tool only Brushless; speed not stated #0, #10 and #20 by depth knob 6 pounds Tool only; biscuits sold separately
WOODSTARTER 8.5 amp plate joiner Corded 8.5 Amp, 12,000 RPM #0, #10 and #20 8.1 pounds Dust bag; 4-inch carbide blade; 100 biscuits
Ecarke cordless plate joiner Cordless, stated as Makita 18V compatible 11,000 RPM #0, #10 and #20; Simplex, Duplex and Max joints not stated Tool only; batteries not included; 80 wafers (title)
Makita PJ7000 plate joiner Corded per the bullets 5.6 amp, 11,000 RPM #0, #10 and #20 5.6 kg not stated
Makita XJP03Z 18V LXT cordless 18V LXT battery (title) not stated #0, #10 and #20 7.6 pounds not stated

Weights converted to pounds

Four listings give a weight in pounds, and the Makita PJ7000 gives its weight in kilograms. We convert the kilogram figure with one formula, pounds = kilograms x 2.2046, and then compare each weight with the 6-pound DEWALT tool-only figure. The comparison is only a first look, because the DEWALT figure is for a tool only and the Makita XJP03Z listing does not say whether a battery is included.

Listing Weight as stated Calculation Pounds Difference from 6 lb
DEWALT DCW682B (tool only) 6 pounds as stated 6.00 0.00
AOBEN 7.6 lbs as stated 7.60 +1.60
Makita XJP03Z 7.6 pounds as stated 7.60 +1.60
WOODSTARTER 8.1 pounds as stated 8.10 +2.10
Makita PJ7000 5.6 kg 5.6 x 2.2046 12.35 +6.35

The Makita PJ7000 is the heaviest stated weight in this set, about 6.35 pounds more than the DEWALT tool-only figure. Seven listings were read, and the other two give no weight, so they are not in this comparison.

The biscuit joiners, one by one

Each section gives the listing’s own description, its stated specs, when the joiner fits, when to skip it, and the limit the listing leaves open.

DEWALT DW682K 6.5 amp biscuit joiner

The listing describes a corded DEWALT joiner with a 6.5 amp, 10,000 rpm motor. It has a dual rack and pinion fence that the listing says keeps the blade and fence parallel, a fence that tilts from 0 to 90 degrees and a 45-degree locating notch for mitered joints. The shoe is aluminum and can be clamped for stationary work.

  • Motor: 6.5 amp, 10,000 rpm (the listing says)
  • Fence: tilts 0 to 90 degrees (the listing says)
  • Biscuit sizes: preset depth stops for all common biscuit sizes (the listing says)
  • Included: not stated

Pick it if you want a corded joiner with a 45-degree notch for mitered joints. Skip it if you need a weight or an included-biscuits list, because the listing gives neither. The limit: the listing says the motor works in the hardest woods, but it does not name the woods it covers.

AOBEN 8.5 amp plate joiner with 110 biscuits

The listing describes a corded 8.5A joiner with a 4-inch tungsten carbide blade, 11,000 rpm and a tilt fence that locks from 0 to 90 degrees. Its title lists 30 No. 0, 30 No. 10 and 50 No. 20 biscuits, and it includes a dust bag. The listing says it joins solid wood, plywood, chipboard, fibreboard and artificial marble from 8 mm material thickness.

  • Motor: 8.5A, 11,000 rpm (the listing says)
  • Blade: 4 in tungsten carbide tipped (the listing says)
  • Groove width: 5/32 in (the listing says)
  • Weight: 7.6 lbs (the listing says)
  • Dimensions: 17 in x 14 in x 5 in (the listing says)

Pick it if you want a corded joiner with a large biscuit count in the box and a manual setting. Skip it if you need a cordless tool, because the listing is corded. The limit: the listing states a material thickness from 8 mm, so thinner stock is outside its stated range.

DEWALT DCW682B 20V MAX XR biscuit joiner, tool only

The listing describes a brushless DEWALT joiner for the 20V MAX XR battery platform. It is sold as a tool only, with biscuits sold separately. The listing says the depth knob sets #0, #10 and #20 biscuits, the fence bevels from 0 to 90 degrees, and tool-free adjustments cover depth, height and bevel. Its overview gives a weight of 6 pounds.

  • Power: battery powered, 20V MAX XR platform (title)
  • Biscuit sizes: #0, #10 and #20 (the listing says)
  • Bevel: 0 to 90 degrees (the listing says)
  • Weight: 6 pounds (overview)
  • Included: tool only; biscuits sold separately (the listing says)

Pick it if you already own a DEWALT 20V MAX XR battery and charger and want the lightest stated joiner here. Skip it if you need a battery and charger in the box, because the listing is tool only. The limit: the listing does not state a motor speed. If you keep a 20V battery in your shop, see our guide to batteries for a DEWALT leaf blower.

WOODSTARTER 8.5 amp plate joiner with 100 biscuits

The listing describes a corded 8.5 amp, 12,000 rpm plate joiner with an aluminum body, a 4-inch carbide blade and 100 biscuits. The biscuits are 50 No. 10 and 50 No. 20. It has a dust bag and an anti-slip handle with a safety lock, and it adjusts from 0 to 90 degrees with several cutting depths.

  • Motor: 8.5 Amp, up to 12,000 rpm (the listing says)
  • Biscuit sizes: #0, #10 and #20 (the listing says)
  • Included: dust bag, 4-inch carbide blade, 100 biscuits (the listing says)
  • Dimensions: 6 in L x 7 in W x 18 in H (overview)
  • Weight: 8.1 pounds (overview)

Pick it if you want the fastest stated motor speed here and a kit with biscuits. Skip it if you want a lighter joiner, since its 8.1 pounds is more than the AOBEN’s 7.6 pounds. The limit: the listing does not state a warranty, so ask the seller before you rely on one.

Ecarke cordless plate joiner, Makita-compatible

The listing describes a cordless plate joiner that it calls compatible with Makita 18V batteries. The batteries are not included. It states an 11,000 rpm motor, 0 to 90 degree angle adjustment, six depth settings, and joints for #0, #10 and #20 biscuits and for Simplex, Duplex and Max joints. The title says tool only and lists 80 wafers.

  • Power: cordless; Makita 18V compatible (the listing says)
  • Motor: 11,000 RPM (the listing says)
  • Angle: 0 to 90 degrees (the listing says)
  • Depth settings: 6 (the listing says)
  • Included: tool only; batteries not included; 80 wafers (title)

Pick it if you already own a Makita 18V battery and want a cordless joiner with a dust bag. Skip it if you need a battery and charger in the box, since the listing is tool only. The limit: the Makita compatibility is the listing’s own claim. This post does not verify it, so check the battery fit with the seller before you buy.

Makita PJ7000 5.6 amp plate joiner

The listing describes a Makita plate joiner with a 5.6 amp motor at 11,000 rpm. It has a cast aluminum pivot fence with three positive stops at 0, 45 and 90 degrees, six depth settings with one-touch stops, and cam locks for the angle guide and fence. The overview field reads hand powered and 110 volts, but the bullets describe a motor, so this post treats the joiner as corded.

  • Motor: 5.6 amp, 11,000 rpm (the listing says)
  • Stops: 0, 45 and 90 degrees (the listing says)
  • Depth settings: six, with one-touch stops for #0, #10 and #20 (the listing says)
  • Weight: 5.6 kg, about 12.35 lb (overview; converted)

Pick it if you want three fixed stops at 0, 45 and 90 degrees and a Makita-branded corded joiner. Skip it if you need a light tool, because its stated weight is the heaviest in this set. The limit: the overview field reads hand powered, which conflicts with the motor in the bullets.

Makita XJP03Z 18V LXT cordless plate joiner

The listing describes a cordless 18V LXT plate joiner with a rack-and-pinion vertical fence, a cast aluminum pivot fence with stops at 0, 45 and 90 degrees, and six depth settings with one-touch stops for #0, #10 and #20 biscuits. The listing says it gives portability in the field or in the shop without a cord. Its overview gives a weight of 7.6 pounds and an amperage of 3 A.

  • Power: cordless 18V LXT (title)
  • Stops: 0, 45 and 90 degrees (the listing says)
  • Depth settings: six, for #0, #10 and #20 (the listing says)
  • Weight: 7.6 pounds (overview)
  • Included: not stated

Pick it if you want a Makita cordless joiner with the same three stops as the corded PJ7000. Skip it if you need to know what is in the box, because the listing does not say whether a battery or charger is included. The limit: the overview field reads hand powered, which conflicts with the cordless title.

How we chose

We searched Amazon for best biscuit joiner on 2026-10-22 and read seven plate joiners. We kept products whose title or bullets describe a plate joiner that cuts biscuit slots. We left out blades for biscuit joiners, router bits, loose biscuits, plastic clamps, a dowel jointer and a renewed Ryobi kit from the same search, because they are different products or a different condition. The search showed no other plate joiners that matched these rules, so the post covers seven. The order of the product sections follows the order in which we read the listings. It is not a ranking, and we did not score the joiners.

What we could not verify

The listings do not say how cleanly any joiner cuts a slot, how well a fence holds its angle over time, or how much dust each joiner collects. We can confirm only what the listings state. The weight comparison above is arithmetic on stated figures, and it does not show how a joiner feels in use.

What the sources do not say

  • The DEWALT DW682K listing gives no weight and no included parts.
  • The Makita XJP03Z listing does not say whether a battery and charger are in the box, and its overview field reads hand powered.
  • The Makita PJ7000 overview field reads hand powered, which conflicts with its bullets.
  • The Ecarke listing’s Makita compatibility is a claim we did not verify.

Buying checklist

  1. Write down the biscuit sizes you use, then check the listing for #0, #10 and #20.
  2. Decide on a cord. The DEWALT DCW682B, Ecarke and Makita XJP03Z are cordless; the other four are corded.
  3. Check whether a battery and charger come with the tool. The DEWALT and Ecarke listings say tool only.
  4. Check the biscuit count if you want a kit. The AOBEN lists 110 and the WOODSTARTER lists 100.
  5. Check the weight if you hold the joiner for long cuts. The stated weights run from 6 pounds for the DEWALT tool only to about 12.35 pounds for the Makita PJ7000.

Mistakes to avoid

  • Buying the DCW682B and expecting a battery in the box. The title says tool only.
  • Assuming the Ecarke fits your Makita battery. The listing states it as a claim, and this post does not verify it.
  • Reading the Makita overview field as the power source. It reads hand powered for both Makita models, which conflicts with the bullets and title.
  • Comparing the Makita PJ7000 weight with the cordless figures without checking the battery. The DEWALT figure is for a tool only.

FAQ

Which biscuit sizes do these joiners cut?

Most listings name #0, #10 and #20 biscuits. The DEWALT DW682K says its depth stops cover all common biscuit sizes, and the Ecarke listing adds Simplex, Duplex and Max joints. The AOBEN adds a manual setting for custom depths.

Do the biscuit joiners include biscuits?

Three listings state a count. The AOBEN title lists 110 biscuits, the WOODSTARTER says it comes with 100, 50 No. 10 and 50 No. 20, and the Ecarke title lists 80 wafers. The DEWALT DCW682B says biscuits are sold separately, and the other listings do not state an included count.

Can I use a cordless biscuit joiner with my Makita battery?

The Ecarke listing says it is compatible with Makita 18V batteries and that the batteries are not included. The Makita XJP03Z is a Makita 18V LXT tool. This post does not verify the Ecarke claim, so check the battery’s fit with the seller before you buy.

Which joiner is the lightest?

The DEWALT DCW682B is the lightest stated figure at 6 pounds, and it is a tool only. The AOBEN and Makita XJP03Z both state 7.6 pounds, and the Makita PJ7000 is the heaviest at 5.6 kg, about 12.35 pounds.

What does a biscuit joiner do?

The listings describe a plate joiner that cuts slots for biscuits. Their own features are a tilting fence for the angle and depth stops for the biscuit size, so the fence and the stop are the settings to check.

Does the DEWALT 20V battery fit other DEWALT tools?

The DEWALT DCW682B listing names the 20V MAX XR platform. For a related battery guide, see our guide to batteries for a DEWALT leaf blower, and for voltage and amp-hour terms see our guide to lawn mower battery voltage and amps.

Bottom line

Choose by power source. If you already own a DEWALT 20V MAX XR battery, the DCW682B is the lightest stated joiner here at 6 pounds, tool only. If you do not, pick a corded joiner, and the WOODSTARTER is the one that comes with the most biscuits, 100, in its listing.
