Craftsman Bis-Kit

Every so often questions come up about the Craftsman Bis-Kit. This is an attachment designed to fasten to the bottom of a Craftsman router which cuts slots for #0, #10 and #20 biscuits. The Bis-Kit sold for about $40 and I had one of these back when I used Craftsman routers. These units were discontinued a couple years ago and I snagged a couple for $15 each. They are not fancy but they work fine for cutting slots to edge join boards, mitered corners and 90° corners. The Craftsman slot cutting bit included in the kit has an OD of 2" with a tooth width of 5/32". If you need a replacement MLCS has a 1-15/16" slot cutter which should work fine. By plunging and releasing the tool you should be able to make quality #11 round biscuit slots. You can download the owners manual from our router reference section.

Not sure but I'll add my 2 cents worth. I do have a dedicated biscuit cutter but I sometimes use a simple slot cutter bit in a table mounted router. That method became necessary when I needed to cut some biscuit slots in fairly thin material that I was using for door frames. I was able to set the height of the biscuit slot precisely for the thin material and also get a more accurate diameter. The dedicated biscuit cutter has a much larger blade so it cuts a wider hole.
