The H250M35 Metal Drill Bit Set is a professional 25-piece HSS M35 cobalt drill bit kit designed for precise and efficient drilling in a wide range of metals. Manufactured from premium HSS M35 high-speed steel with 5% cobalt, these drill bits provide excellent heat resistance, outstanding wear resistance and extended service life.
The set includes the most commonly used drill sizes from 1.0 to 13.0 mm in 0.5 mm increments, making it an ideal solution for professional workshops, manufacturing facilities and maintenance technicians.
Precision-ground cutting edges ensure accurate centring, smooth drilling starts and efficient chip removal, resulting in cleaner holes and improved drilling performance.
The drill bits are suitable for drilling stainless steel, carbon steel, alloy steel, structural steel, cast iron, aluminium and other non-ferrous metals, but are not intended for fully hardened steel.
Recommendation: when drilling stainless steel or other hard metals, use a low drilling speed, consistent feed pressure and appropriate cutting lubricant. This reduces heat generation and significantly extends tool life.
The complete set is supplied in a durable metal storage case for convenient organisation, protection and transport.
