V Groove Router Bit Set CNC Engraving Miter Cutter Chamfer Bevel V Grooving Bits 60/90/120 Degree 3D Making Woodworking Cutting Tool, 6mm Shank

The bits arrived on-time and in good shape. Packaging was fine. They appear to be perfectly wonderful bits. However, they are a 6mm shank and like most US folks, I have a 1/4" collet so I can't use them at all. It's my own stupid fault, they are clearly listed as 6mm.

Haven't had a chance to use these yet but look like quality bits. Will follow up when I get the change to put them to good use

This bit is a 1/4" or 6mm however it will not fit in your dewalt router.It will fall out.For this to fit you need to put a shim around an shaft in order for it to fit tight in the router.But the price is not bad for the product.Good for cutting numbers on PVC board.

Bits are dull. Not finely honed and shiny. Tried two of the 60 degree bits on my CNC router to cut Red Oak. Slow speed, shallow cut and they only lasted for about ten minutes each. Even at the beginning, the cuts were ragged and fuzzy. Had to throw the first piece away because it was so bad but was able to salvage the second.

6mm equals .23 inches, cannot use with my CNC machine... disappointed I didn't read this closer, but more so, who makes a .23 inch router bit... oh well.

i have used the bits for lettering and v-carving in plastic and soft woods with not issue, cuts were clean and tips ran centered. the shank is 6mm, not as issue with a metric ER11 collet set.

This set is of excellent quality and works well with my CNC router. Combined with a good cam engraving program such as the CamBam plugin, you’ll be very satisfied with the results.
