Drill Bit GRAPHITE SDS+ 14 mm for concrete, model 57H458

GRAPHITE SDS+ 14 mm drill bit for concrete, model 57H458, is a rotary hammer accessory engineered for drilling into concrete and masonry. The bit has an SDS+ shank for quick and secure fitting into compatible rotary hammers and a 14 mm diameter suitable for medium-sized holes used in fixing, anchor installation and general construction tasks. The design focuses on reliable penetration of concrete and brick while maintaining a standard geometry appropriate for repetitive drilling work.

Advantages

The SDS+ shank ensures fast tool changes and firm retention in rotary hammers, reducing slippage during impact drilling. A 14 mm diameter provides a balance between hole size and drilling speed for typical anchor and fixing applications. The bit is made to withstand the impact forces of rotary hammers and offers consistent drilling performance in concrete and masonry when used with appropriate drilling parameters and drill units.

Suitable for

• Drilling holes for anchors and fasteners in concrete and masonry
• Installing electrical boxes, conduit clips and plumbing fixings
• General construction and repair tasks requiring medium-sized holes

Key specifications

• Shank type: SDS+ for rotary hammer quick-fit connection
• Drill diameter: 14 mm suitable for medium holes and anchors
• Intended material: concrete and masonry
• Typical use: rotary hammer percussion drilling

How to use

Select a compatible rotary hammer with SDS+ chuck and set the tool to the hammer-drilling mode. Mark the drilling point, secure the work area, and start drilling at low speed to create a guide recess, then increase pressure and maintain firm, steady contact while allowing the tool's impact action to do the cutting. Periodically withdraw the bit to clear dust and debris from the hole to ensure efficient drilling and to reduce heat buildup.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) and, where possible, employ dust extraction or a vacuum adapter. For reinforced concrete, check for rebar before drilling and use a suitable carbide or rebar-compatible bit if necessary. Match the drill diameter to anchor or fixing manufacturer recommendations for secure installations.
