The IDEAL 35-517 Step Drill, (1/4-Inch to 1-3/8-Inch) has a 1-Inch long shank with a self-starting point that eliminates starter holes or punches. It has a double0fluted design for balanced cuts and cooler operations. The unique titanium coating extends the drill life six times longer than other step drills. In 1916, J. Walter Becker started the Ideal Commutator Dresser Company of Chicago from his mother"s kitchen. He manufactured commutator dresser stones with the belief that every product should be worth more than the price paid for it. Service, he said, was part of the product. That idea has been the core IDEAL business principle for over 90 years. Today, the many loyal distributors and customers that make IDEAL successful are a testament to Becker"s original philosophy.
