Bosch HSS-G Metal Drill Bit DIN 338 6.5 x 101 mm

This 1-piece Bosch HSS-G DIN 338 metal drill bit, sized 6.5 × 101 mm, is designed for drilling accurate holes in dense materials. Made from high-speed steel, it handles demanding substrates including alloyed steel, unalloyed steel, steel castings, and grey cast iron. It also cuts reliably through iron powder ceramics, malleable cast iron, non-ferrous metals, and hard plastics. The 6.5 mm diameter suits standard mid-sized hole-making tasks in metalworking, assembly, or fabrication work. A ground tip ensures reliable starting and steady progress through the workpiece.

A standard cylindrical shank allows the bit to lock firmly into conventional rotary drill chucks. Built for professional and experienced DIY applications, it provides clean, controlled operation without needing specialised adapters. The bright finish improves visibility against dark workpieces during use and routine inspection. Weighing just 22 grams, the bare bit stays well balanced during continuous rotation. This configuration relies on standard rotary motion rather than hammer action to clear material efficiently from the hole.

• 101 mm overall length with a 63 mm working length sets the maximum drilling depth per pass.
• 135-degree split-point angle reduces bit wandering and improves initial centring on smooth surfaces.
• Dual cutting edges ensure consistent swarf clearance during high-speed rotary drilling.
• Complies with DIN 338 design standards for standardised dimensional accuracy across tool setups.
• Rated for effective drilling in alloyed and unalloyed steel up to a maximum tensile strength of 900 N/mm².
