Drill bit EINHELL Glasbor 5 mm — glass/ceramic short shank

EINHELL Glasbor 5 mm — glass/ceramic short shank is a purpose-made 5 mm diameter drill bit for clean and controlled drilling in glass and ceramic materials. Its short shank design reduces flex and improves control during delicate drilling tasks, making it suitable for precise holes required when fitting fixtures or carrying out small repairs. The bit is intended for use at low speeds with compatible hand drills or drill presses and should be used with appropriate cooling or protective measures to avoid thermal damage and chipping.

Advantages

The short shank construction provides increased stability and reduced vibration compared with longer bits, helping to produce accurate, neat holes in brittle materials. The 5 mm diameter is convenient for common installation tasks and small repairs. Using the bit at controlled low speeds and with cooling reduces the risk of cracking and extends the effective service life of the cutting edge. The design is compatible with standard drill chucks on hand drills and drill presses intended for glass and ceramic work.

Suitable for

• Drilling holes in glass panes for fittings and hardware
• Creating openings in ceramic tiles for plumbing fixtures
• DIY repairs that require precise small-diameter holes in brittle materials
• Workshop tasks using drill presses at low speed with coolant

Key specifications

• Diameter: 5 mm
• Shank type: short shank for improved stability
• Material suitability: glass and ceramic
• Recommended speed: low RPM for brittle materials
• Intended use: manual drills and drill presses with appropriate cooling

How to use

Secure the workpiece firmly on a stable surface and mark the drilling point. Fit the 5 mm Glasbor into a compatible drill chuck and set the drill to a low speed. Begin drilling with steady, moderate pressure; avoid forcing the bit. For glass and ceramic, use water or other suitable coolant at the drilling point to dissipate heat and reduce chipping. If available, use a drill press or guide to maintain perpendicular alignment and improve precision. After drilling, withdraw the bit slowly and inspect the hole for chips or cracks.

Usage recommendations

Operate at low speeds, apply coolant during drilling, and clamp workpieces securely. Use a drill guide or press for increased accuracy and avoid lateral force to minimize the risk of splitting or cracking brittle materials.
