Diamond drill bit for tiles 12 mm Diam SX — Diam DISX012N, professional

Diamond drill bit for tiles 12 mm Diam SX — Diam DISX012N is a professional diamond-tipped drill bit designed to create precise 12 mm holes in ceramic, porcelain and similar tile materials. Intended for use with handheld drills and drill presses, this bit provides clean round holes required for plumbing fixtures, electrical passthroughs and tile finishing. The diamond cutting edge maintains shape and cutting performance when used with correct speed and cooling, making it suitable for installation and repair tasks involving wall and floor tiles.

Advantages

The diamond cutting rim ensures accurate, low-chipping drilling on glazed surfaces and dense porcelain tiles. Its 12 mm cutting diameter delivers consistent hole size for fittings and anchors. Compatibility with both handheld drills and drill presses allows use in varied working conditions. When used with water or light cooling, the bit resists overheating and preserves the diamond matrix for extended service life.

Suitable for

• Drilling holes for plumbing fixtures through ceramic and porcelain tiles
• Creating passthroughs for electrical conduits and cables in tiled walls
• Tile installation and repair tasks requiring precise 12 mm holes
• Work with handheld drills or drill presses with appropriate speed and cooling

Key specifications

• Cutting diameter: 12 mm
• Tip type: diamond-tipped cutting rim
• Recommended materials: ceramic tiles, porcelain tiles and similar glazed surfaces
• Suitable tools: handheld drills and drill presses
• Cooling: water or light continuous cooling recommended

How to use

Secure the tile or workpiece to prevent movement and mark the drill position. Use a moderate drill speed and apply light, steady pressure; avoid excessive force that can cause cracking. Start drilling at a low speed to establish the hole, then maintain consistent speed. Apply a continuous water stream or periodic wetting to cool the bit and remove debris. For thicker or very hard porcelain, proceed gradually and allow the bit to cool between passes.

Usage recommendations

Wear appropriate personal protective equipment such as safety glasses and gloves. Use a drill guide or template for perpendicular holes and ensure stable clamping of tiles to reduce chipping. Do not use impact/drilling hammer mode. For best lifetime and performance, keep the cutting edge cooled with water during operation and avoid prolonged dry runs.
