Spotting Drill Bit: 10 mm, 90°, TiN Coated High Speed Steel, 93 mm Overall Lg

High-speed steel spotting drills are the most common choice for a wide range of drilling applications. High-speed steel spotting drills are typically less brittle than cobalt or carbide tools. TiN coating is a general purpose coating that protects against wear and has a ceramic coating that is hard and heat resistant. TiN resists impact better than TiAlN and AlTiN coatings. It has a coating oxidation temperature of 550°C and a coating hardness of 2300 HV. Right Hand spotting drills have cutting edges that move clockwise around the shaft for use in standard drills that rotate clockwise.
