Bosch SDS plus-5 Hammer Drill Bit 8 x 165 mm

The Bosch SDS plus-5 Hammer Drill Bit 8 x 165 mm is a single masonry accessory designed for intensive rotary hammer applications. It is engineered specifically to penetrate dense building materials and is fully rated for concrete, brick, limestone, and stone. A dedicated centering tip allows the operator to start holes cleanly without the drill wandering on rough or uneven surfaces. Fluted cutting geometry continuously channels debris away from the drilling zone as the bit advances. This efficient dust removal reduces friction, lowers operating temperatures, and prevents binding in deep holes.

Brazing and hardening techniques are applied directly to the cutting area to maintain structural integrity under load. This targeted thermal treatment reduces operational vibration, helping to minimise user fatigue during extended construction tasks. Both standard rotary drilling and active hammer drilling functions are supported to accommodate varying masonry densities. The design caters to professionals and serious DIY users who need reliable performance when preparing surfaces for structural fittings. Consistent power transmission from the drill chuck ensures the bit maintains a steady cutting speed throughout the job.

• 100 mm maximum working length defines the deepest achievable hole per pass.
• Carbide drill bit material withstands the repetitive impact forces generated by rotary hammers.
• Standard SDS Plus shank ensures a secure, tool-free connection and prevents slippage.
• Integrated wear mark provides a visual reference to confirm the bit is still producing accurate hole diameters.
• Manufactured in Germany to meet strict production standards and precise engineering tolerances.
