Carbide Tipped Glass Drill Bits

Bits used for drilling through glass and tile.

Precision, Supreme quality, Tru-Cut Glass & Tile Bits, made in the USA, are expertly designed for drilling into some of the most challenging materials, including glass, tile, porcelain, and ceramics. These glass & tile bits are proudly manufactured in Cary, Illinois, ensuring the highest quality and performance standards. With their polished finish and solid high-grade tungsten carbide construction, these glass & tile bits provide excellent dust ejection and longevity, making them indispensable tools for both professionals and DIY enthusiasts.

Available in Single Tip Quad Tip and Diamond Head configurations, these bits utilize a polished bright finish that maximizes dust ejection for cleaner work environments.

The Single Tip & the quad-tipped design features solid high-grade tungsten carbide, allowing for smooth and precise hole creation. The long carbide tip not only provides durability but also allows for multiple regrinds, extending the life of these glass & tile bits, even when drilling tough materials.

The Diamond Head glass & tile bits have diamond heads with the same premium grade diamond particles that you would find on our Continuous rim tile blades.

Tru-Cut glass & tile bits can be used wet or dry and feature an innovative aspic tongue design that helps gauge the depth of drilling accurately. The sharpened ogival point ensures that you start with a precise hole without any wandering, which is critical for achieving high-quality results.

These glass & tile bits are sold individually by the dozen, allowing for mix-and-match options to meet your specific project needs. Or you can purchase them in sets (3 per order) For larger quantity orders, customers are encouraged to call for customized pricing.

Operating Instructions:

• Select the appropriate Tru-Cut bit type and size for your material and task.
• Use a low drill speed (400–1000 RPM) to prevent overheating and extend bit life when drilling glass, tile, porcelain, or ceramics.
• Mark your drilling location with tape or a marker to help prevent bit wandering.
• Secure the workpiece firmly using clamps or a vice to avoid movement.
• For dry drilling, ensure good dust extraction and drill slowly with light, steady pressure. For wet drilling, apply water to the drilling area or use a water holder to cool the bit and reduce dust.
• Start drilling at a slight angle to establish a starting point, then move to a perpendicular position as the bit bites into the surface.
• Maintain steady, gentle pressure—let the glass & tile bits do the work to prevent damage or breakage.
• Periodically stop to clear away dust or slurry to optimize cutting and cooling.
• Once the hole is finished, carefully withdraw the bit at low speed and inspect your work.

Handling Information:

• Store glass & tile bits in a dry place, ideally in their original cases or a bit organizer to prevent dulling or damage.
• Clean bits after each use by wiping away dust, debris, or moisture; dry thoroughly if bits were used wet.
• Regrind carbide tips on Single and Quad Tip bits as needed to extend usable life, using the proper equipment.
• Regularly inspect bits for wear or damage before each use.
• Keep different bit sizes and types organized and clearly labeled, especially if ordering mix-and-match sets.

Safety Information:

• Always wear safety glasses or goggles, gloves, and a dust mask when drilling; use hearing protection for prolonged work.
• Ensure the material being drilled is firmly clamped or supported to prevent slipping.
• Use water or the designated water holder for wet drilling to minimize heat and dust, especially with delicate materials.
• Operate at recommended speeds—high speeds can lead to bit breakage or overheating.
• Avoid using excessive force or pressure while drilling with these glass & tile bits.
• Keep hands, clothing, and loose items clear of the rotating drill bit, and avoid touching bits immediately after use as they may be hot.
• Ensure drill and bits are compatible and in good condition before beginning work.
• Do not use damaged or excessively worn bits; dispose of them according to local regulations.

Q: Are there discounts for bulk orders?
A: Yes, quantity discounts are available, and customers are encouraged to call for custom pricing on large orders.

Q: What makes the Single Tip bits unique?
A: The Single Tip bits feature a solid high-grade tungsten carbide tip, known for delivering smooth, precise holes and enduring multiple regrinds, making them highly cost-effective for both professionals and DIYers.

Q: Why choose the Quad Tip bits?
A: Quad Tip bits have an advanced four-point carbide design that offers enhanced stability and faster cutting speeds. This reduces tip wandering and creates cleaner holes, particularly useful when working with hard tiles or porcelain.

Q: What are the benefits of the Diamond Head bits?
A: Diamond Head bits use premium-grade diamond particles in their construction, ideal for ultra-hard or delicate materials like glass and high-gloss ceramic. They’re excellent for minimizing chipping and producing ultra-smooth hole edges.

Q: How does the ogival point help in drilling?
A: The sharpened ogival point ensures accurate start points without the drill bit wandering, which is essential for precision work on slick or brittle surfaces.

Q: What is the aspic tongue design, and how does it help?
A: The innovative aspic tongue design helps users visually gauge drilling depth for improved accuracy and control, reducing material waste and over-drilling.

Q: Can I use these bits in both corded and cordless drills?
A: Yes, Tru-Cut Glass & Tile Bits are compatible with most standard corded and cordless drills. Always ensure your drill can operate at the lower speeds recommended for drilling hard materials.

Q: What is the best way to extend the life of my bits?
A: For longest life, operate at appropriate speeds, minimize pressure, use water for cooling on tough jobs, and take advantage of the regrindable tip features where possible (Single & Quad Tip).

Q: Are the bits suitable for both professional and DIY use?
A: Absolutely! Their versatility, durability, and range of tip styles make them excellent for professional tradespeople and home improvement projects alike.
