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

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.

Just what I need for the project I am doing with my daughter

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.

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.

This is a great bit for cnc use. Cuts great and the extra long reach is exactly what was needed. Will definitely buy again

I was using this for the first time and the bit broke on me within a minute of use

Cuts nice and clean

I needed a long 1/8 end mill so I bought this one. It broke on the first pass. My depth setting was .o4.

Broke in first 4 min .1 DOC 45 in/min speed. I bought 2 because they were same day shipping and needed them ASAP and I was afraid one would break. Ran the second bit at .09 ODC and 40 in/min and it worked fine.
