This 6-piece M35 high speed steel center drill set, alloyed with 5% cobalt and finished with a TiAlN coating, is designed for producing precise center holes before turning or milling. The cobalt provides strength and heat resistance, while the TiAlN coating improves wear protection and extends service life, especially when cutting tougher metals.

Each drill is single-fluted and ground with a 60° countersink angle for standard machine center alignment. The right-hand cut design supports stable operation and chip evacuation in higher-speed conditions on lathes and milling machines.

The set covers sizes #1 through #5, with two pieces of #1, one piece of #2, and one each of #3, #4, and #5, ranging from 3/64" to 3/16". The drills are supplied in a protective plastic case for organized storage and transport.
