D1 & D3 Drag Knife for CNC Routers

Our D1 & D3 Drag Knives are optimized for detailed work in thinner materials with a depth of cut from 0.010 in. to 0.0625 in. (1/16 in.) thick. Curved cuts as small as 1/16 in. radius are possible with these tools.  The D1 fits in a 1/2in collet and the D3 fits in a 1/4in collet.

D2 & D4 Drag Knife for CNC Routers

Our D2 & D4 Drag Knives can handle thicker materials from 0.010 in. up to 0.250 in. (1/4 in.) thick. Curved cuts as small as 1/8 in. radius can be made with this tool. The D2 fits in a 1/2in collet and the D4 fits in a 1/4in collet.

* If you are cutting material thicker than 1/8in, the minimum cut radius on the D2 or D4 increases to the material thickness

** Offset values are approximate because results may vary from machine to machine and material to material. In general, if your blade is overturning at corners, reduce the offset. If it is under turning, increase the offset.
