Drill bit GRAPHITE 8 mm for concrete, cylindric shank (57H332)

GRAPHITE 8 mm concrete drill bit with a cylindric shank (model 57H332) is designed for efficient drilling in concrete, masonry and similar hard materials. The bit features a solid carbide tip for high hardness and wear resistance and a spiral flute that facilitates rapid dust evacuation and stable chip removal. Its cylindric shank fits standard three-jaw chucks in handheld rotary drills and drill drivers, making it suitable for common construction and renovation tasks such as fixing anchors, inserting plugs and creating through-holes.

Advantages

The solid carbide tip provides precise cutting performance and extended service life compared with standard high-speed steel points. Spiral flutes ensure effective removal of drilling debris, which reduces friction and helps maintain consistent drilling progress. The cylindric shank offers universal compatibility with many cordless and corded rotary drills and provides stable clamping in the chuck. Overall, the bit balances durability and drilling efficiency for repetitive masonry work.

Suitable for

• Drilling holes for anchors and wall plugs in concrete and solid masonry
• Creating through-holes for cable routing and conduit installation
• Fixing fixtures, brackets and fittings to concrete or block walls
• General renovation and light construction drilling tasks in hard materials

Key specifications

• Diameter: 8 mm
• Tip material: solid carbide
• Shank type: cylindric shank suitable for standard chucks
• Flute type: spiral flute for efficient dust removal
• Intended material: concrete, masonry and similar hard substrates

How to use

Select an appropriate drilling speed and, if available, enable the hammer function on the rotary drill when working with concrete or dense masonry. Mark the drilling point, secure the work area, and clamp the drill bit firmly in the chuck. Begin drilling with light pressure to establish the hole, then apply steady force while allowing the bit and drill to do the work. Periodically withdraw the bit to clear dust from the hole and prevent overheating; use cooling breaks if drilling multiple holes in succession.

Usage recommendations

Wear appropriate personal protective equipment, including safety glasses, dust mask and hearing protection. Use a vacuum or compressed air to clear dust when possible, and select drill speeds and hammer settings according to material density. Replace the bit if the cutting performance noticeably decreases to avoid oversized holes or increased load on the drill.
