Drill bit GRAPHITE 10 mm for concrete, cylindrical shank (57H318)

GRAPHITE drill bit 10 mm for concrete with a cylindrical shank (model 57H318) is designed for drilling precise round holes in concrete and similar hard masonry materials. It is intended for use with rotary and hammer drills that accept cylindrical shanks and offers straightforward drilling for installing anchors, dowels, through-holes and other common construction and renovation tasks.

Advantages

The drill bit's 10 mm diameter and rigid carbide tip deliver stable penetration and consistent hole diameter in reinforced concrete, brick and stone. The cylindrical shank provides reliable grip in standard drill chucks, while a robust fluted body removes debris effectively to reduce clogging and overheating. The geometry of the cutting edge is optimized for impact and rotation modes, helping to maintain drilling speed and extend tool life under typical site conditions.

Suitable for

• Drilling anchor and dowel holes in concrete and masonry
• Making through-holes for pipes and cables in renovation works
• Pilot holes for mechanical fixings and supports
• General light-to-medium construction and installation tasks

Key specifications

• Diameter: 10 mm
• Shank type: cylindrical (straight)
• Intended material: concrete and similar hard masonry
• Recommended drill types: rotary and hammer drills with cylindrical shank chucks
• Tip material and design: carbide-tipped cutting geometry for impact drilling
• Flute: spiral flutes for efficient dust and debris evacuation

How to use

Secure the drill bit in the drill's chuck, ensuring the cylindrical shank is fully inserted and tightened. Select an appropriate drill mode: use hammer mode for reinforced concrete and rotary mode for softer masonry. Start at low speed to position the bit, then increase to the recommended speed for the material while applying steady, moderate pressure. Periodically retract the bit to clear dust and prevent clogging, and allow the bit to cool if heavy drilling generates excessive heat.

Usage recommendations

Wear appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask. Use a depth stop or marking to control hole depth for anchors, and keep the drill perpendicular to the surface for accurate holes. Replace the bit when chipping or loss of cutting efficiency becomes noticeable to maintain hole quality and reduce drill motor strain.
