Triangle Glass & Tile Drill Bit Set 6-12mm

Precision drilling for glass, tile and stone without cracks or chips

This triangle drill bit set is engineered for accurate, controlled drilling in brittle and dense materials such as glass, ceramic tile, porcelain, rock slab and similar surfaces. The special eccentric cutting geometry and triangular tip help the bit start exactly where you place it, reducing wandering and minimizing surface damage, even on smooth or glazed finishes.

Each bit is manufactured from high-hardness material to withstand friction and heat during continuous drilling. The set includes four commonly used diameters - 6 mm, 8 mm, 10 mm and 12 mm - giving you flexibility for small mounting holes through to larger openings for anchors, pipes or fixtures. The eccentric design supports angled drilling where standard bits struggle, helping you work around edges, corners and tight spaces with greater control.

The triangular cutting head improves chip removal and reduces the risk of cracking by distributing pressure more evenly across the drilling surface. When used with appropriate cooling (such as water) and moderate speed, these bits deliver clean, round holes with reduced chipping on the entry and exit points. Suitable for professional trades and workshop use, they integrate easily with most standard drill chucks.

Why It's a Smart Choice

• Designed for glass, tile, ceramic and rock slab to reduce cracking and chipping
• Four sizes (6/8/10/12 mm) cover common mounting and installation needs
• Eccentric, triangular tip improves positioning accuracy and hole quality

FAQ

Q: Which materials are these drill bits suitable for?
A: They are intended for glass, ceramic tile, porcelain, rock slab and similar brittle or dense surfaces. Always test on an offcut if you are unsure about the material.

Q: Can I use them with a regular electric drill?
A: Yes, the bits are compatible with most standard electric drills. Use low to medium speed and avoid hammer mode when working on brittle materials.

Q: Do I need to use water or coolant?
A: Using water as a coolant is recommended for glass, tile and stone to control heat, extend bit life and improve hole quality.

Q: Are these suitable for deep holes?
A: They are best for shallow to moderate-depth holes typically required for mounting hardware, fittings and fixtures. For very deep holes, drill gradually and cool the bit regularly.
