Questions & Answers

What is your mill's speed in inches per minute? My available no-load rpms are 8,000-10,000. 24,000 rpm is the speed at which the engine rotates. Any ideas would be greatly appreciated. ?

In my CNC, I run at 18000rpm and find that it cuts hard woods nicely.

What is the tapered angle, and what does it mean?

I believe the number is six. It's only 2 degrees outside, but I'm not in my shop right now. I'll double-check tomorrow and get back to you, but I believe it's 6 o'clock. 2 degrees Celsius.

Selected User Reviews For SpeTool Spiral Tapered Ball Nose End Mill 1/4 X 3 inches Router Bit with 0.75mm Ball Nose 4.36 Deg for CNC Machine Engraving Carving Bits

This is a high-quality bit that is also reasonably priced

5/5

I've used this end mill a few times now, and it's still cutting like new. It's probably had about 20 hours of use time. I can't tell the difference in performance between this end mill and end mills that cost a lot more. br>I returned and bought four more in various sizes. br>Be aware that the diameter given for the ball nose is the radius, not the actual diameter. In round numbers, 060" equals 1/16" diameter. The radius is required by some CNC software, while the diameter is required by others.

Excellent craftsmanship

5/5

I was a little hesitant about getting this bit at first, but since it came highly recommended, I figured it was worth a shot. br>I've been using it to carve Corain and make 3d models out of hard wood. WOW! It has been used for more than 60 hours and is still as sharp as the day it was purchased. They cut so cleanly that fuzzies are no longer an issue. They are now my go-to tool bits!.
