Drill bit GRAPHITE SDS+ 10 mm for concrete, model 57H426

GRAPHITE SDS+ 10 mm drill bit (model 57H426) is a carbide-tipped masonry bit designed for drilling into concrete using SDS+ rotary hammer systems. The 10 mm diameter provides a balance between speed and control for making holes for anchors, dowels and through-fastening in solid and reinforced concrete. Its shank is shaped for SDS+ chucks to ensure secure fit and efficient impact energy transfer during rotary hammer operation.

Advantages

The carbide tip improves wear resistance and maintains cutting performance when penetrating hard materials. The SDS+ shank ensures quick, tool-free bit changes and reliable retention during high-impact drilling. The 10 mm diameter is versatile for common anchor sizes and general masonry tasks, offering stable drilling with reduced wobble compared to smaller-diameter bits.

Suitable for

• Drilling anchor and dowel holes in solid concrete
• Installing masonry fasteners and through-bolts
• Light to medium-duty demolition and renovation work
• Professional and DIY concrete drilling with SDS+ rotary hammers

Key specifications

• Diameter: 10 mm
• Tip material: Carbide
• Shank type: SDS+
• Intended material: Concrete and masonry
• Typical use: Hammer drilling with rotary hammer tools

How to use

Secure the drill bit firmly into the SDS+ chuck of a compatible rotary hammer. Mark the drilling location and, where possible, use a center punch or pilot mark for accuracy. Operate the rotary hammer in hammer-drill mode, applying steady forward pressure without excessive force to allow the carbide tip and hammer action to remove material. Withdraw the bit periodically to clear dust and debris and maintain drilling efficiency. For deeper holes, use compressed air or a brush to remove residue from the hole before inserting anchors.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, hearing protection and dust mask. Match drill speed and impact settings to the material and hole diameter; avoid overheating the bit by allowing cooling pauses during extended drilling. Replace the bit when cutting performance noticeably declines to maintain clean, accurate holes.
