Drill bit for glass KREATOR 12 x 100 mm

Drill bit for glass KREATOR 12 x 100 mm is designed for drilling precise round holes in glass and other brittle materials. The tool features a specialized tip geometry and a rigid straight shank that provide controlled cutting and reduced chipping when used at low rotational speeds. This 12 mm diameter, 100 mm length bit is intended for applications such as glazing, mirror installation and DIY projects where accurate, clean holes are required.

Advantages

The specialized tip reduces the risk of cracking and minimizes surface chipping around the hole. A rigid shank ensures stable centering in the drill chuck and consistent cutting depth. The bit's length offers sufficient reach for thicker panes or when access is limited, while compatibility with standard drills makes it suitable for workshop and on-site use. The design supports slow-speed drilling and steady feed control for improved hole quality.

Suitable for

• Drilling holes in glass panes and mirrors
• Glazing and window frame installations
• Creating pass-through holes for fixtures in brittle ceramic or similar materials
• DIY projects requiring precise round holes in glass

Key specifications

• Diameter: 12 mm
• Overall length: 100 mm
• Tip: specialized for brittle materials (glass-optimized geometry)
• Shank type: straight/rigid for standard drill chucks
• Recommended operating speed: low RPM for glasswork

How to use

Secure the workpiece to prevent movement and mark the drilling position. Use a drill with adjustable speed and fit the bit into the chuck firmly. Begin at low rotational speed with light, steady pressure; allow the bit to cut gradually rather than forcing it through the material. For improved centring, consider using a starter guide or a small amount of removable adhesive to hold the bit at the marked point. Keep the drill perpendicular to the surface throughout the operation. After penetrating the material, reduce pressure and finish the hole carefully to avoid chipping when exiting.

Usage recommendations

Maintain low RPM, use constant light feed pressure, and secure the glass to minimize vibration. Use water or a suitable coolant sparingly if recommended for the specific glass type to reduce heat buildup. Inspect the bit for wear before use and replace if the tip shows rounding or chipping.
