## Long description

Diamond crown drill bit 1/4" O25 mm by MILWAUKEE is a rotary cutting tool designed to create clean, precision holes with a 25 mm diameter. Engineered for use on hard materials such as ceramic, porcelain, glass and stone, this bit features a 1/4" hex shank compatible with most cordless and corded drills that accept hex-shank accessories. The design supports drilling tasks in tiling, sanitary installations and general renovation where accurate, chip-free holes are required.
Advantages
The diamond cutting edge provides efficient material removal and extended wear resistance when used on abrasive surfaces. The 1/4" hex shank ensures secure retention in the drill chuck or quick-change adapter and reduces slippage during operation. The bit delivers smooth, accurate holes with minimal chipping on brittle materials, helping to maintain the integrity of tiles and glass. Its compatibility with common drills makes it convenient for both professional tradespeople and DIY users.
Suitable for
 Drilling 25 mm diameter holes in ceramic and porcelain tiles
 Creating holes in glass for fixtures or pass-throughs
 Installing sanitary fittings such as faucets and shower heads
 Precision holemaking in stone and masonry for anchors or pipes
Key specifications
 Tip material: industrial diamond grit for cutting and abrasion resistance
 Diameter: 25 mm cutting crown
 Shank type: 1/4" hex shank for secure quick-change and chuck use
 Intended materials: ceramic, porcelain, glass, natural stone and similar hard substrates
 Recommended use: wet or dry drilling depending on material and manufacturer guidance
How to use
Mount the diamond crown drill bit into a drill with a compatible 1/4" hex chuck or quick-change holder and secure it firmly. For best results, mark the drilling point and start at low speed to establish the cut, then apply steady, moderate pressure while maintaining drill speed appropriate for the material. For ceramic, porcelain and glass, consider using a backing support under the workpiece to reduce breakout. Use water cooling or intermittent drilling to reduce heat and extend tool life when working on dense stone or prolonged drilling tasks. Follow the drill and bit manufacturer's safety guidance and wear appropriate eye and hand protection.
Usage recommendations
Use slow to medium drilling speed and light, consistent pressure for brittle materials; incorporate water or cooling where possible to prolong bit life and improve hole quality. Avoid excessive force or high speed which can cause glazing of the diamond segments or cracking of the workpiece.
