The Donek Tools 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 Donek 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.
Donek 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. Whether you want to perform delicate veneer inlay work or cut out cardboard boxes with your CNC router, Donek Tools has a tool right for the job.
Tools that fit in 1/2in and 1/4in collets are available.
We have extensive detailed information on the capabilities of these tools and how to used them on the other pages of this site. If you can't find answers to your questions, send us an e-mail at [email protected] or give us a call to inquire further. We can be reached by phone at 303-913-4263
Compare Drag Knife Models
We offer four different models:
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.
1/2" Drag knife for CNC Router
Our 1/2" Drag knife can handle thicker materials from 0.010 in. up to 0.50 in. (1/2 in.) thick. Curved cuts as small as 4.25 in. radius can be made with this tool. The 1/2" knife fits in a 1/2in collet.
|Maximum Depth of Cut:||1/16in||1/4in||1/16in||1/4in||1/2in||NA|
|Minimum Cut Radius:||1/16in||1/8in*||1/16in||1/8in*||4.25in||NA|
|Approximate** Offset Value:||0.065in
* 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.
