Pro Tips for Best Results
- When drilling through hard materials such as glass, marble, granite, or tile, use water to cool the bit during use.
- Apply gradual, even pressure — never force the bit.
- Start drilling at a slight angle, then gradually transition to a vertical position for precise, clean entry.
- Always wear appropriate eye protection when drilling.

Frequently Asked Questions
Q: What materials can these eccentric drill bits cut through?
A: These four-edged eccentric drill bits are designed for a wide variety of hard materials, including glass, ceramic tile, porcelain, mirrors, brick walls, concrete, marble, granite, flower pots, wood, and thin metal sheets. Their carbide-tipped cross-head design makes them effective across all these surfaces.
Q: Are these hex shank drill bits compatible with standard handheld drills?
A: Yes. The hex shank design is compatible with the vast majority of handheld drills and drill drivers. The hex shank provides a secure, non-slip grip that keeps the bit firmly in place during use, reducing wobble and improving accuracy.
Q: Do I need to use water when drilling glass or tile?
A: It is strongly recommended to use water as a coolant when drilling through hard, heat-sensitive materials such as glass, tile, marble, and granite. Keeping the bit cool extends its lifespan and helps prevent cracking or chipping of the material being drilled. Start at a slight angle and slowly transition to vertical drilling for the cleanest result.
Q: What sizes are included in the 7-piece set?
A: The set includes seven bits in the following sizes: 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, and 12mm — giving you a comprehensive range for most common drilling tasks around the home or on the job site.
