General Purpose HSS Drill Bits – M2 High Speed Steel Jobber Length for DIY & Workshop Use
Product Overview
The M2 HSS jobber drill bit is a versatile and cost-effective cutting tool designed for general-purpose drilling. Manufactured from M2 grade high-speed steel, it offers excellent toughness, good wear resistance, and reliable performance across a wide range of materials. With options for 118° or 135° split point tips, these drill bits deliver smooth starts, accurate positioning, and efficient chip evacuation. Produced by XINGRUI, they are an ideal choice for workshops, maintenance, and industrial users requiring dependable drilling tools at a competitive price.
Manufacturing & Design
M2 high-speed steel provides a balanced combination of hardness and toughness, making it suitable for both professional and DIY applications. Each drill bit is fully ground to maintain concentricity, reduce vibration, and achieve precise hole sizing. Depending on requirements, the drill bits can be supplied with a bright finish, black oxide, or TiN coating to enhance durability and extend service life. The straight shank design ensures compatibility with standard keyed and keyless drill chucks.
