Drill bit GRAPHITE SDS+ 10 mm for concrete, model 57H434

GRAPHITE SDS+ 10 mm drill bit (model 57H434) is designed for drilling clean, accurate holes in concrete and masonry. The bit has an SDS+ shank to fit SDS+ rotary hammers and delivers percussion drilling performance suitable for creating anchor and dowel holes with a 10 mm cutting diameter. It is intended for construction and installation tasks that require a robust carbide tip and stable centring during impact drilling into concrete, brick and similar materials.

Advantages

The SDS+ shank ensures quick, secure fitting and efficient power transfer from SDS+ rotary hammers, reducing slippage during heavy-duty percussion. The 10 mm diameter is a common size for standard anchors and dowels, allowing consistent hole sizing for reliable fixation. The tip geometry and material composition are optimised for masonry and concrete to provide improved drilling speed and extended service life compared with general-purpose twist bits when used under percussion mode.

Suitable for

• Drilling anchor and dowel holes in concrete and reinforced concrete.
• Making openings for plugs and fasteners in masonry and brick.
• Installation work requiring repeated percussion drilling with an SDS+ rotary hammer.
• Light to medium construction and renovation tasks where a 10 mm hole is required.

Key specifications

• Shank type: SDS+ for compatible rotary hammer tools.
• Cutting diameter: 10 mm suitable for standard anchors and dowels.
• Application: concrete, masonry and brick.
• Working mode: percussion (hammer drilling) with rotary motion.
• Tip: carbide or hard-wearing material designed for impact drilling.

How to use

Install the drill bit into the SDS+ chuck of a compatible rotary hammer until it locks in place. Select a hammer-drilling mode on the tool when drilling into concrete or masonry. Start drilling at low speed to establish the hole position, then apply steady pressure while allowing the tool's percussion action to do the cutting. Withdraw the bit periodically to clear dust and debris from the hole, especially when drilling deep holes for anchors. After use, clean the flute and tip to maintain performance and inspect for wear before the next job.

Usage recommendations

Use suitable personal protective equipment including eye protection, hearing protection and a dust mask when drilling concrete. For reinforced concrete, check for embedded reinforcement and use appropriate procedures if rebar is encountered. Match the drill diameter to the anchor or dowel specifications and avoid excessive axial force to prevent premature wear or breakage of the bit.
