About the Tool
Drag Knife can be used to cut almost anything you would cut with a utility knife, but with the speed and precision of a CNC router.
The Drag Knife fits into your CNC router or spindle collet, making it a universal fit for almost any CNC router available. The tools were designed to use a utility knife blade (though a specific type) which dramatically reduces the cost of consumable blades.
Drag Knives are being used in industry and by hobbyists to cut snowboard and ski base materials, wood veneer for inlay/marquetry artwork, leather, carbon fiber pre-preg laminates for aerospace, military, and automotive components, cardboard for custom packaging, and much more.
Use the Drag Knife to vastly enhance the capabilities of your CNC router.

1 & 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.
