Diamond Crown Hex 32 mm drill bit, MILWAUKEE – diamond core bit for masonry and concrete

MILWAUKEE Diamond Crown Hex 32 mm drill bit is a 32 mm diamond core bit engineered for drilling through masonry, concrete and other hard mineral substrates. The tool combines a diamond-segment cutting crown with a robust steel body and a hexagonal shank for secure retention in hammer drills, rotary hammers with adapter chucks and impact drivers where applicable. It is suitable for both wet and dry drilling strategies depending on the material and cooling chosen, and is intended for creating clean, precise circular holes for plumbing, electrical conduits, anchors and installation work.

Advantages

The diamond-segment cutting edge provides fast penetration and long service life when working on abrasive masonry and concrete. The hex shank improves torque transfer and reduces slippage in the chuck for consistent hole positioning. The segmented crown design optimizes dust and water evacuation during drilling, which supports efficient cutting and helps maintain core integrity. The construction balances durability with manageable weight for ease of handling during repetitive installation tasks.

Suitable for

• Drilling holes for plumbing pipes in concrete and brick
• Creating openings for electrical conduits and cable routing
• Installing anchor bolts, fastening points and through-holes in masonry
• Professional and trade installation work requiring accurate round holes in hard mineral materials

Key specifications

• Cutting diameter: 32 mm
• Cutting material: diamond segments
• Shank type: hexagonal shank for secure retention
• Intended materials: concrete, masonry and other hard mineral substrates
• Drilling modes: suitable for wet and dry drilling depending on application and cooling

How to use

Select the appropriate drill and adapter for the hex shank, clamp the bit securely in the chuck or holder, and position the drill perpendicular to the work surface. Start at low speed to establish a pilot groove, then increase speed and apply steady pressure; allow the diamond segments to do the cutting rather than forcing the bit. For wet drilling, provide a steady water flow to cool the cutting segments and remove debris. For dry drilling, use intermittent operation and lift the bit periodically to clear dust and reduce heat build-up. Maintain stable support of the workpiece and wear appropriate personal protective equipment.

Usage recommendations

Use this diamond core bit with compatible drills and observe recommended rotation speed ranges for 32 mm core bits in concrete; prefer wet drilling for extended life when access to water is possible, and monitor segment wear to replace the bit before performance deteriorates.
