## Summary description

Irwin 7 mm glass drill bit designed for drilling clean holes in glass and similar brittle materials. Suitable for use with handheld drills at low speed and light pressure; recommended with cooling or lubrication to prevent overheating and chipping. Ideal for DIY glass projects, installing fixtures in glass panels, and craft work requiring precise 7 mm holes.

## Long description

The Irwin 7 mm glass drill bit is designed for creating precise 7 mm holes in glass and other brittle materials. It features a tip geometry suitable for controlled cutting on smooth, non-porous surfaces when used with a handheld drill at low speeds and light pressure. The bit is intended for applications where clean, accurate holes are required without excessive cracking or chipping when proper drilling technique and cooling are applied.
Advantages
This 7 mm glass drill bit provides consistent hole size and improved stability compared with improvised or general-purpose bits. Its tip profile reduces walking on the surface of glass and helps initiate the cut cleanly. When used with cooling or lubrication and slow drill speed, it minimizes thermal stress and chipping at the hole edge. The bit is compact and easy to handle for small-scale or detailed work.
Suitable for
Drilling 7 mm holes in tempered or annealed glass (with appropriate precautions)
DIY glass projects and craft work requiring precise round holes
Installing fixtures, mounts, or fasteners in glass panels and mirrors
Thin ceramic tiles and other brittle sheet materials where controlled cutting is needed
When it may not be suitable
This glass drill bit is not intended for high-speed drilling or heavy feed pressure; using it under such conditions increases the risk of cracking, chipping, and rapid wear. It is also not suitable for drilling thick, reinforced, or heavily tempered safety glass without specialized equipment and expert technique. For masonry, metal, or wood applications, a purpose-designed masonry or metal drill bit should be used instead.
Key specifications
Nominal drill diameter: 7 mm
Intended materials: glass and other brittle sheet materials
Recommended operation: low drill speed with light pressure
Cooling: recommended use of water or lubricant to reduce heat and chipping
Typical use case: handheld drills for small to medium DIY and craft tasks
How to use
Secure the glass workpiece on a flat, stable surface with protective backing to support the area around the hole. Mark the drilling point and, if possible, use a guide or template to keep the bit aligned. Start drilling at very low speed and apply only light, steady pressure; allow the bit to cut gradually rather than forcing it. Continuously apply cooling fluid or water to the tip to dissipate heat and clear debris. After penetrating the glass, reduce pressure and finish the hole slowly to avoid chipping the exit side. Clean the bit and work area after use.
What to consider before purchase
Verify that a 7 mm hole is the correct size for the intended fasteners or fixtures
Ensure compatibility with the drill you will use (speed control and chuck size)
Plan for cooling/lubrication and proper clamping to reduce breakage risk
Assess the type and thickness of glass to determine if specialized methods or equipment are required
Usage recommendations
For best results, use the Irwin 7 mm glass drill bit at low RPM in a drill with good speed control, keep the cutting area wet, and support the glass close to the drilling point. Wear safety glasses and gloves, and proceed with slow, steady pressure to minimize cracking and ensure a clean 7 mm hole.
