SpeTool Tapered 4 36Deg Machine Engraving Review

Using this accessory, our team found that the taper angle was not consistent throughout the cut, leading to jagged edges and uneven lines. The only positive aspect was the initial sharpness of the tool upon first use. However, this quickly diminished after only a few cuts. Overall, we do not recommend this product for precision engraving work.

I was skeptical at first about getting this bit but as it came highly recommended I thought it might be worth a try. Wood. WOW! Over 60 hours on it and it's still as sharp as the day it was new. They cut so cleanly that fluffy cleaning is a thing of the past. My new tool bits!

I've used this end mill a few times, it probably lasted about 20 hours. It still cuts like new. Compared to end mills that I paid a lot more for, I can't tell the difference in performance with this one. I actually went back and bought 4 more different sizes. So the actual diameter is 0.060 inch, call it 1/16 inch diameter in round numbers. Some NC programs require a radius, some a diameter in the tool designation.
