Diamond-tipped Drill Bit 10 mm, INDIAN PROFESSIONAL KORONA DIAMENTOWA HEX, dry drilling

Diamond-tipped Drill Bit 10 mm from INDIAN PROFESSIONAL (KORONA DIAMENTOWA HEX) is a dry-drilling accessory designed for creating clean, small-diameter holes in hard surfaces. The 10 mm cutting head is coated with diamond grit to increase abrasion resistance and extend tool life when working on tile, ceramics, natural stone and similar materials. A hex shank enables secure seating in impact drivers and drills without slipping, supporting controlled, accurate drilling in renovation and construction tasks.

Advantages

The diamond-coated cutting edge offers improved wear resistance and consistent performance when drilling abrasive or hard materials. The 10 mm size allows precise hole placement for fixtures, anchors and fittings. The hex shank ensures a firm grip in chucks and quick-change holders, reducing cam-out and enabling faster bit changes. The design supports dry drilling to avoid the need for coolant in many on-site situations, improving convenience for repair and installation jobs.

Suitable for

• Drilling holes in ceramic and porcelain tiles
• Creating openings in natural and engineered stone
• Installing anchors, fittings or fixtures in tiled surfaces
• Small-diameter precision work during renovation and repair

Key specifications

• Cutting diameter: 10 mm
• Tip: diamond grit coated for abrasion resistance
• Shank type: hex shank for secure fit in impact drivers and drill chucks
• Drilling method: dry drilling suitable for on-site use
• Intended materials: tile, ceramics, stone and similar hard surfaces

How to use

Mark the drilling position and ensure the workpiece is stable. Fit the hex shank into the driver or drill chuck and tighten securely. Start drilling at low speed to establish the hole, then apply steady, moderate pressure while maintaining alignment. For tiled surfaces, begin at a slight angle if needed to prevent slipping, then straighten the bit once a pilot groove is formed. Avoid excessive force or high speed that could overheat the bit or damage the material.

Usage recommendations

Use personal protective equipment such as safety goggles and gloves. When possible, periodically withdraw the bit to clear dust and reduce heat buildup. For prolonged or repeated use, consider intermittent drilling pauses to keep the diamond tip effective and to extend bit life.
