When one end wears out, switch to the opposite end for two times the life of a standard carbide end mill. Made of solid carbide, these end mills are harder, stronger, and more wear resistant than highspeed steel and cobalt steel for the longest life and best finish on hard material. Use them to round sharp corners on the edge of your workpiece.

To produce optimum arc stability, diamond grinding of tungsten electrodes should be done with the axis of the electrode perpendicular to the axis of the grinding wheel. The diamond grinding wheel should be reserved for grinding only tungsten to eliminate possible contamination of the tungsten tip with foreign matter during the grinding operation.

Straight vs. Tapered There are generally two forms of end mills: straight and tapered. This is a choice based on the geometry of your finished part because a tapered end mill won't be able to do all the same things as a straight end mill, and a straight end mill may not be the most efficient choice.

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.

Now I just need to grind that into a precision machine taper. I only put down a bead on each end of the taper. Matching the whole cone to the drill chuck's taper would be too difficult with an angle grinder! I made a block to fit on the end of the shaft and mounted that in my four jaw lathe chuck. I also mounted a wooden bearing to hold the end ...

The ends of end mills, even multifluted end mills, can be successfully ground back by hand, although it's a bit of a struggle to get all the teeth cutting in a common plane without a cutter grinder. That shouldn't prevent you from using a small square and some carefully applied grinding to rebuild the end of the cutter.
