Bosch High-Performance HSS-G Twist Drill Bit 65mm Overall Length, 3.1mm Shank Size, 10 Piece Set 2608585481

Bosch 2608585481 HSS-G Drill Bit Set encompasses 10 precision-engineered drill bits with a 65mm overall length and 3.1mm cylindrical shank designed for professional metalworking and mechanical applications. Crafted from high-speed steel (HSS-G), these bits deliver excellent heat resistance, durability, and sustained cutting performance.

The drill bits feature a 135-degree self-centring split-point tip as per DIN 338 standards, which ensures excellent positional accuracy while eliminating the need for pilot holes or pre-punching for diameters up to 10mm. The right-hand helical twist design aids rapid removal of swarf for efficient drilling and cleaner holes.

These bits are suitable for high-speed drilling into alloyed and non-alloyed steels, cast irons, sintered iron, malleable cast iron, non-ferrous metals, and hard plastics. Their precision ground formation provides up to 40% higher drilling speeds with 50% less feed pressure compared to standard HSS drill bits, enhancing productivity in industrial, workshop, construction, and manufacturing environments.

Conforming to DIN 338 and DIN 1414 standards, this set ensures consistent quality and durability required for professional use. The smooth finish and cylindrical shank of 3.1mm diameter enable compatibility with most standard drill chucks (non-SDS types),. These bits are optimized for both hand tools and machine drills, making them versatile for various applications.

High-quality HSS-G material for enhanced wear resistance. 135-degree split-point tip for self-centering and accurate drilling. Right-hand helical twist design for quick chip evacuation. Overall length of 65mm suitable for jobber drill length tasks.

Smooth, cylindrical shank of 3.1mm diameter for secure chuck fitting. Compliance with DIN 338 and DIN 1414 manufacturing standards. Includes 10 pieces, ideal for professional and industrial use. Designed for drilling steel, cast iron, non-ferrous metal, and plastic materials.

This Bosch HSS-G drill bit set is essential for engineers, metalworkers, and craftsmen seeking reliable and efficient drilling tools. Whether used on construction sites, workshops, or manufacturing floors, these drill bits deliver consistent performance while reducing operation time and effort.
