## Summary description

MILWAUKEE Diamond Crown M14 30mm is a 30 mm diameter diamond core drill bit with M14 thread designed for drilling precise holes in hard materials such as concrete, reinforced concrete, masonry and stone. Suited for use with compatible M14-threaded angle grinders or drill adapters, it delivers clean cutting for installations, plumbing, electrical and contractor tasks.

## Long description

MILWAUKEE Diamond Crown M14 30mm diamond core drill bit is a 30 mm diameter core designed for clean, accurate hole cutting in hard building materials. With an M14 threaded connection it fits compatible angle grinders and adapters, enabling contractors and tradespeople to create neat openings for plumbing, electrical installations and anchor fixing in concrete, reinforced concrete, masonry and natural stone. The cutting segment is engineered to maintain shape and performance during repetitive drilling in abrasive substrates.
Advantages
The diamond-segment cutting edge provides fast penetration and long wear life when used on dense materials. The M14 thread ensures secure mounting to compatible grinders and adapters, reducing play and improving control. The 30 mm diameter offers a common size for through-holes and service penetrations while the crown-style design helps produce cleaner hole walls and reduced chipping compared with non-diamond bits. The bit is suitable for repeated use in demanding jobsite conditions when used within the recommended operating parameters.
Suitable for
Drilling holes for plumbing pipes and conduits in concrete and masonry
Creating access and service penetrations for electrical installations
Forming anchor and dowel holes in reinforced concrete and stone
Site maintenance tasks that require precise, round openings in hard substrates
Key specifications
Diameter: 30 mm
Thread type: M14 (suitable for angle grinders and threaded adapters)
Tip: diamond-segment crown for cutting hard and abrasive materials
Primary materials: concrete, reinforced concrete, masonry, natural stone
Design: crown/core bit for through-holes and service penetrations
How to use
Select a compatible angle grinder or drill adapter with an M14 threaded mount and fasten the Diamond Crown M14 30mm core bit securely according to the tool manufacturer's instructions. Mark the hole position, start drilling at a steady speed with moderate pressure, and maintain a perpendicular angle to the work surface for a clean cut. For deeper holes, use intermittent withdrawal to clear dust and allow cooling; for wet drilling, follow safety and tool guidelines for water use. Always ensure the workpiece is stable and supported before drilling.
Usage recommendations
Use appropriate personal protective equipment (safety glasses, dust mask, hearing protection and gloves), clamp or support the workpiece, and follow the angle grinder or adapter manufacturer's speed and operating limits. For extended life and cleaner holes, consider using water cooling where the tool and environment permit, and replace the bit when cutting performance noticeably decreases.
