## Summary description

GRAPHITE SDS+ drill bit 12 mm (model 57H442) designed for drilling into concrete. Compatible with SDS+ rotary hammer chucks, it provides a 12 mm diameter hole for anchoring, fastening and installation tasks. Intended for use in construction and renovation when drilling into concrete, masonry and similar substrates with SDS+ power tools.

## Long description

GRAPHITE SDS+ drill bit 12 mm (model 57H442) is designed for efficient drilling in concrete and masonry with SDS+ rotary hammer chucks. The 12 mm diameter creates standard-sized holes for anchors, wall plugs and through-fixings used in construction and renovation. The bit's shank is compatible with SDS+ systems, enabling secure seating in hammer drills and consistent energy transfer for percussive drilling into dense substrates.
Advantages
The solid carbide tip and spiral flute geometry ensure effective material removal and reduced jamming during drilling. Precision ground flutes maintain a consistent hole diameter and help evacuate dust, while the robust shank design provides reliable retention in SDS+ chucks. The drill bit is optimized for repeated use in concrete and masonry tasks, delivering predictable hole quality and stable drilling performance.
Suitable for
Drilling anchor and fastening holes in concrete and reinforced concrete
Preparing fixing points for electrical boxes, conduit clips and plumbing brackets
Installation of wall plugs, expansion anchors and threaded rods
Renovation and repair tasks that require percussive drilling in masonry
Key specifications
Diameter: 12 mm
Shank type: SDS+ compatible
Intended materials: concrete, masonry, stone-like substrates
Tip: carbide or carbide-tipped geometry for concrete drilling
Flute design: spiral for efficient dust removal
Typical use: percussive drilling with rotary hammer
How to use
Secure the drill bit in the SDS+ chuck according to the power tool manufacturer's instructions until it clicks into place. Select a hammer-drill mode suitable for concrete and apply steady axial pressure while allowing the tool to perform the percussive action; avoid excessive force which can reduce bit life. Begin at low speed to establish a guide recess, then increase to normal working speed. Periodically withdraw the bit to clear dust from the hole and prevent overheating.
Usage recommendations
Use personal protective equipment including safety glasses, hearing protection and a dust mask when drilling. Match hole depth and diameter to the anchor or fastener specifications, and replace the bit when wear or loss of cutting efficiency is observed to maintain clean, accurate holes.
