Notes on my very limited use of the Universal Cutter Grinder: I purchased a Norton straight cup wheel for a 3/4" spindle which was rated for this unit's RPM. I was unable to sharpen end mills with this wheel, in particular I could not grind the third angle (i.e. gash) although this would likely have been possible with a taper cup wheel.

A typical end mill may be referred to as an "Upcut Spiral" by the CNC Router world. Other than small geometry changes to optimize for wood, end mills and upcut spirals are interchangeable. The more common spelling is "end mill", but I often use "endmill" as well. The two are pretty interchangeable.

For going 1/16" deep I would probably make 6 passes if using a 1/16" end mill at .010/pass. It takes a little longer but will leave a cleaner slot. One thing to remember that if you are using an endmill the same width as the slot, you are cutting both conventional and climb at the same time so one side of the slot will look a little worse than ...

Building a Brooks-Stent Cutter Grinder. Last Modified: Click to Enlarge .

Sharpening an End Mill using an off hand grinder, Harold Hall Most home workshop users will consider sharpening end mills a non starter due to the complications of sharpening its edges. This is understandable and whilst I have provided designs for doing this I consider it is only worthwhile if the milling machine is made considerable use of.

If someone is interested in a project, I have about 90% of a K.O. Lee air spindle head for grinding end mills. What's missing is the base with the tilt lever to move the end mill to and from the wheel. The original collets have been replaced by $150 worth of precision bushings (which is what I'd sell it for). The air spindle seems to work well.

I dig in my used end mills drawer to find one with decent edges left. If it is a 4 flute I grind back two of the cutting edges 180 apart so all I have to worry about is two cutting edges. Being in job shop all my life were one offs are common and often the customer is in a hurry and the job has to be ready by the AM you learn
