Τρυπάνι KWB 051380 για γυαλί και πλακίδια, διάμετρος 8 mm, μήκος 120 mm

Drill bit KWB 051380 for glass and tile, 8 mm diameter, 120 mm length is a straight, purpose-made bit for making precise holes in brittle materials such as glass and ceramic tile. With an overall length of 120 mm and an 8 mm cutting diameter, the bit is designed to be used with manual or low-speed drills and, when used with proper technique and coolant, helps reduce cracking and chipping around the drilled hole.

Advantages

The bit’s straight shank and dedicated cutting geometry provide controlled penetration and stable guidance when working on brittle surfaces. Its 8 mm diameter gives an accurate hole size for fixtures and fittings, while the 120 mm length allows for drilling through thicker tiles or for reaching recessed areas. The design reduces the need for repeated passes, and when combined with low drill speed and cooling, it helps minimise surface damage.

Key specifications

How to use

Mark the drilling position and secure the workpiece to prevent movement. Use a manual or low-speed electric drill fitted with the straight shank of this bit and start at low speed to avoid sudden catches. Apply light, steady pressure and keep the bit cool by using water or a suitable coolant to reduce heat and minimise chipping. If drilling through tile, begin at the glazed surface and maintain perpendicular alignment to the workpiece. Withdraw the bit periodically to remove debris and allow cooling.

Recommendations

Wear eye protection and gloves. Avoid high-speed drilling and excessive pressure; use continuous cooling when possible. For laminated or tempered glass, confirm suitability before drilling, as some glass types may require specialist tools or techniques.
