Build Your Shortlist｜Carbide Tipped Glass Drill Bits｜ Tools & Hardware

Tru-Cut Glass & Tile Bits are precision-engineered drill bits designed for drilling through some of the most challenging materials, including glass, tile, porcelain, and ceramics.
 Proudly manufactured in Cary, Illinois, USA, these bits are built with premium materials and advanced manufacturing techniques to deliver superior performance, durability, and accuracy.
Featuring polished finishes and solid high-grade tungsten carbide construction, Tru-Cut Glass & Tile Bits provide excellent dust ejection, extended service life, and cleaner drilling results. Available in Single Tip, Quad Tip, and Diamond Head configurations, these bits are designed to meet the needs of both professional contractors and DIY users.
The Single Tip and Quad Tip designs feature solid tungsten carbide tips that create smooth, precise holes while allowing multiple regrinds to extend bit life. The Diamond Head configuration uses premium-grade diamond particles similar to those found on continuous rim tile blades, making it ideal for ultra-hard and delicate materials.
Tru-Cut Glass & Tile Bits can be used for both wet and dry drilling and feature an innovative aspic tongue design to help accurately gauge drilling depth. The sharpened ogival point allows for precise starting without wandering, ensuring clean and accurate holes.

Operating Instructions

Select the appropriate Tru-Cut Glass & Tile Bit type and size for your material and application.
Operate at a low drill speed between 400–1000 RPM to reduce overheating and extend bit life.
Mark the drilling location with tape or a marker to help prevent bit wandering.
Secure the workpiece firmly using clamps or a vice to prevent movement.
For dry drilling, use proper dust extraction and apply slow, steady pressure.
For wet drilling, apply water to the drilling area or use a water holder to cool the bit and reduce dust.
Begin drilling at a slight angle to establish a starting point, then move to a perpendicular position once the bit engages.
Apply steady, light pressure and allow the bit to cut naturally.
Periodically clear dust or slurry from the hole to maintain cutting efficiency.
Withdraw the bit slowly after completing the hole and inspect the finished result.

Handling Information

Store bits in a dry location, preferably in original cases or a bit organizer.
Clean bits after each use by removing dust, debris, and moisture.
Dry thoroughly after wet drilling applications.
Regrind Single Tip and Quad Tip carbide tips as needed to extend bit life.
Inspect bits regularly for wear or damage before use.
Keep different bit sizes and styles organized for easy identification.

Safety Information

Always wear safety glasses, gloves, and a dust mask when drilling.
Use hearing protection during extended drilling operations.
Secure materials firmly before drilling to prevent movement.
Use water or a designated water holder for wet drilling applications.
Operate at recommended speeds to prevent overheating and breakage.
Avoid excessive pressure while drilling.
Keep hands, clothing, and loose objects away from rotating drill bits.
Verify drill and bit compatibility before use.
Do not use damaged or excessively worn bits.
