Diamond drill bit Makita P-42014 6.8 cm 1 pc(s)

The Makita P-42014 diamond drill bit with a 6.8 cm cutting diameter is designed for controlled drilling in very hard materials such as ceramic, porcelain, glazed tiles and natural stone. Supplied as a single piece, this diamond-core bit offers a stable cutting edge and consistent hole quality for tasks requiring accurate round openings. The construction balances cutting efficiency and wear resistance to deliver predictable performance on masonry surfaces commonly encountered in home improvement and professional installation work.

Advantages

This diamond drill bit provides precise, clean-hole cutting in hard surfaces while maintaining dimensional stability and long service life. Its diamond-embedded cutting edge reduces chipping and minimizes the need for finishing after drilling. The single-piece supply ensures you receive a ready-to-use tool without additional assembly. The bit is compatible with standard core drilling procedures and is suitable for use with water-cooling to extend tool life and reduce dust.

Suitable for

• Drilling round openings in ceramic and porcelain tiles
• Creating holes in natural stone and granite tiles
• Masonry and tile installations where clean edges are required
• Plumbing and electrical installations that require precise circular apertures

Key specifications

• Cutting diameter: 6.8 cm
• Tool type: diamond core / diamond drill bit
• Quantity: 1 piece
• Intended materials: ceramic, porcelain, glazed tile, natural stone, masonry

How to use

Attach the diamond drill bit to a compatible drill or core-drilling adapter according to the drill manufacturer’s instructions. For best results, secure the workpiece and mark the drilling position. Begin at low speed to establish the cutting path, then maintain moderate speed while applying gentle, steady pressure. Use a continuous water feed or intermittent wetting to cool the bit and remove debris; this reduces heat buildup and extends the life of the diamond segments. After completing the hole, allow the bit to cool before storing.

Usage recommendations

Operate the bit with appropriate personal protective equipment including eye protection and gloves. For brittle tiles, consider starting with a small pilot guide or a backing support to reduce cracking. Do not apply excessive axial force; let the diamond segments perform the cutting. Regularly flush the drilling area with water to optimize cutting performance and prolong tool life.
