Bosch HSS-G Metal Drill Bits, Long Series, 3mm (Pack of 5)

Bosch 2608596812 HSS-G Metal Drill Bits are precision-engineered for maximum performance in metal drilling applications. These long-series drill bits feature a 3mm diameter with a working depth of 65mm and an overall length of 98mm, making them ideal for deep-hole drilling.

Designed with an advanced 135-degree self-centring split-point tip, these bits combine active cutting with perfect centring to minimise wandering, ensuring accurate and consistent results. The split-point design eliminates the need for pre-punching or pilot drilling for holes up to 10mm, saving valuable time and effort.

Manufactured from high-speed steel (HSS), these bits deliver up to 40% faster drilling speeds and 50% lower feed pressure compared to standard HSS drill bits. Ideal for alloyed and non-alloyed steel, cast iron, hard plastics, and non-ferrous metals such as aluminium, copper, and titanium, these drill bits are built for durability and precision.

Key Benefits:

• Fast & Efficient - Reduces drilling time with superior material penetration.
• No Pre-Drilling Required - Self-centring tip avoids pilot holes.
• Optimised for Metal - Covers all major ferrous and non-ferrous metals.
• DIN 338 Compliant - Precision-ground to meet industrial standards.

Technical Specifications:

• Material: High-Speed Steel (HSS-G)
• Flute Angle: Type N
• Point Angle: 135° with split-point tip
• Shank Type: Cylindrical (equal to drill bit diameter)
• Diameter Tolerance: h8

Perfect for use in drill stands, drill drivers, and general metalworking applications, these Bosch HSS-G drill bits ensure high-quality, precise results every time.
