Concrete Drill Bit GRAPHITE 12 mm cylindrical shank model 57H336

GRAPHITE 12 mm concrete drill bit with a cylindrical shank, model 57H336, is designed for drilling into concrete, masonry and similar hard materials. It is compatible with rotary and hammer drills that accept cylindrical (round) shanks and provides a precise 12 mm hole diameter suitable for installing anchors, dowels and through-holes in construction and renovation projects.

Advantages

The drill bit is manufactured to deliver consistent hole diameter and straightness when used with appropriate drilling equipment. Its 12 mm cutting profile ensures a clean, well-defined bore for secure anchor seating. The cylindrical shank provides easy mounting in drill chucks that do not accept SDS systems, enabling use with a wide range of rotary and hammer drills. The carbide-tipped design and flute geometry improve debris evacuation and extend service life under normal working conditions.

Suitable for

• Drilling anchor and dowel holes in concrete and masonry
• Creating through-holes for through-bolts and fasteners
• Preparation work in renovation and light to medium construction tasks
• Use with rotary or hammer drills that accept cylindrical shanks

Key specifications

• Diameter: 12 mm
• Shank type: cylindrical (round) shank compatible with standard chucks
• Intended materials: concrete, masonry and similar hard substrates
• Typical uses: anchor and dowel hole drilling, through-holes

How to use

Select a drill with a chuck that accepts cylindrical shanks and secure the 12 mm GRAPHITE bit firmly in the chuck. Mark the drilling point, start at low speed to establish the position, then apply steady feed pressure and increase speed appropriate to the drill and material. For deeper holes, periodically withdraw the bit to clear dust and debris and to prevent overheating. When drilling reinforced concrete, proceed cautiously and avoid excessive force if the bit contacts rebar.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask. For best results, match drill speed and feed pressure to the concrete hardness, and allow the bit to cool between long drilling runs. Replace the bit when wear degrades cutting performance or hole accuracy.
