SpeTool Extra Long Spiral Router Bit Down Cut 1/8 inch Cutting Diameter, 1/4 inch Shank 3 inch OVL HRC55 Solid Carbide End Mill for Wood Cut Carving Engrave

I ran this bit on my cnc machine at 60 inches per minute, pass depth of 0.1 inch spindle speed at 10,000 and carving oak 1/2 plywood it broke within a couple minutes. I didnt expect that.

Broke under normal carving parameters.

Broke almost immediately and was cutting with its set specs listed...so so disappointing..

Sharp and well made

No issues with this bit whatsoever at first. I use it on my X-Carve and it works perfect! The bad part that it became dull in about a month or so. Does not have a long life. If you buy just keep that in mind.

Spe is one of my favorite bits. They really last a long time and they stay sharp for a long time. Ive only broke a few but its usually because of user error

Broke on the third pass on the MDF my students were cutting.

The bit snapped after routing out a few butterfly joints. Lasted less than an hour of use.

This bit was clean cutting and long enough for my 3/4” thick material (wood) on my XCarve!

Made all the cuts I needed with ease. I was nervous some of the more demanding cuts would break it, but I was wrong. This bit is a champ.
