Diamond drill bit Distar 17982445080 — 8 mm diameter, for hard materials

Diamond drill bit Distar 17982445080 — 8 mm diameter, for hard materials is a precision cutting tool designed for drilling holes in hard, dense substrates. The 8 mm diameter bit features a diamond-impregnated cutting tip that provides increased wear resistance and effective cutting on ceramics, natural and engineered stone, porcelain, glazed tile and similar construction materials. It is intended for through-holes and spot drilling during construction, renovation and installation work using compatible rotary or drill equipment.

Advantages

The diamond cutting edge ensures longer service life and more consistent hole quality compared with conventional HSS or carbide bits when used on hard and abrasive surfaces. Its compact 8 mm size allows precise, controlled drilling for fixtures, anchors and fittings. The bit is compatible with standard drill chucks and works efficiently with moderate feed rates and appropriate cooling, reducing chipping and thermal damage to the workpiece.

Suitable for

• Drilling holes in ceramic tiles and porcelain
• Installing anchors and fixtures in natural stone and engineered stone
• Creating through-holes in glazed and dense tiles
• Spot drilling for plumbing, electrical and finishing installations

Key specifications

• Tip material: diamond-impregnated cutting segment
• Shank type: round shank suitable for standard drill chucks
• Diameter: 8 mm
• Intended materials: ceramics, porcelain, natural stone, engineered stone, glazed tiles
• Typical use: through-holes and spot drilling

How to use

Mark the drilling point and secure the workpiece to prevent movement. Start drilling at low speed to establish a stable center and then apply steady, moderate pressure. Use intermittent operation or a light flow of water as cooling/lubrication when drilling dense or glazed materials to reduce heat and dust. Avoid excessive force or high speed to prevent bit wear, chipping of the material or cracking. After drilling, withdraw the bit carefully and clean the hole of debris.

Usage recommendations

Use a compatible drill with a reliable chuck and, when possible, a depth stop to control hole depth. Employ continuous or periodic water cooling for extended bit life when working on very hard or thick tiles. Replace the bit if cutting performance declines significantly to maintain hole quality and safety.
