This auction is for 12 Stellite Drills @ $150.00. (that averages $12.50 each) You will probably never find this many drills again at this price. Stellite drills are used for drilling hardened steel, even HSS steel. Used for drilling hard materials over 51C Rockwell. This type of drills are used in a drilling machine at a high speed and with considerable pressure. They rely on friction causing the job to get red hot locally so the drill can penetrate. Using a fast speed hold the drill to the work with a firm pressure . At first nothing happens, then as the temperature builds the work piece gets hotter and hotter locally, and suddenly the drill just punches throught the work. Stellite doesn't exist in a soft state so the heat has little effect on it. These drills need to heat the component to penetrate and cause metallurgical changes in the material drilled. Sizes are 1/2", 27/64, 13/32", 3/8", 11/32", 5/16" (x3) , 1/4", 2/16", 11/64", and 5/32". A total of 12 bits. The 3/16" and the 11/64" were used once and still in great usable condition. 10 bits are Deloro and the 11/64" and the 27/64" are the Black Drill Co. There are at least $500 to$600.00 worth of bits. 10 are new old stock. I have used stellite drills several times and they are easy to use and work well.
