76HA center drill bits conform to the American National Standards Institute (ANSI) and have a 118 degree pilot and 60 degree cone recommended for creating center holes in shafts for secure holding. They have a bright finish which prevents workpiece material from sticking to the cutting surfaces of the tool so you get a clean and accurate hole, whilst the tools are manufactured from premium High Speed Steel and can be used to drill many materials including steels, aluminum and stainless steel. 76HA drills are double ended which makes them very economical and increases productivity for each tool. They can also be used in both CNC and conventional machines so are also very versatile.
