Grinding flats on endmills - Industrial Forum - eMastercam

We always grind flats for setscrews when using Endmill holders, sometimes with a grinder and sometimes by hand. It's too much risk to simply rely on the setscrew since this is purely frictional force. You really run the risk of a minor movement in length and not catching it until you have a bucket of scrap.

End Mill Sharpening on Surface Grinder - Practical Machinist

4) Cup grinding wheel. just seems easier to use a cup wheel. i usually only grind 0.0005 to 0.002" per pass. There are primary and secondary angles on periphery and end cutting edges. So 4 adjustments and grinds to sharpen a badly dulled end mill. Frankly I just save a lot of old end mills as it is much faster to sharpen many of the same size.

The Anatomy of an End Mill - In The Loupe

The overall reach of an end mill, or length below shank (LBS), is a dimension that describes the necked length of reached tools. It is measured from the start of the necked portion to the bottom of the cutting end of the tool. The neck relief allows space for chip evacuation and prevents the shank from rubbing in deep- pocket milling applications.

Introduction to Milling Tools and Their Application

Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket. The most common options are 2, 3, or 4 flutes. The more flutes, the more cutting edges but the narrower the channel for chip evacuation.
