Use a plunge rate of 50% or less of the feed rate. So for a feed rate of ... ft/min, use a plunge rate of ... ft/min or less.

Carbide is what professional metal machinists use to make complex items like car engines. It stays sharp 50x longer than conventional CNC router bits.

If you are using a mask with this bit, it will prevent the mask from lifting up along the cut edges. I used it to carve a Tree of Life image (high detail) and it worked very well. It also cuts leaving a perfectly clean edge, no tearout (and no sanding).

These bits are top quality. Order them and they will be at your shop within a few days. I have a drawer of bits from IDC. You can’t beat them.

You'll want to include a collet with this bit if you have a 1/4" collet in your CNC router. You can order that by clicking here.

Chip loads are provided as ranges. In order to extend the life of your tool, use the lower value in the range. If need to get your job done quickly then you can a higher chipload within the specified range.

This did a nice job and helped me identify a tramming issue. I was surfacing BE maple and had done three sides (on two pieces) with the feed rate at half the recommended HW speed. On the fourth side the bit snapped clean off at the collet.

This bit is made like all the others on this site...built to last. That's why these are made above industry standards and 100% tungsten carbide.

Feed Rate = Spindle Speed (RPM) * Number of Flutes * Chip Load (inches) = Spindle Speed * Number of flutes * Chip Load = Answer inches/min
