Frequently Asked Questions
Q: What materials can the eccentric triangle drill bits cut through?
A: These high-hardness eccentric triangle drill bits are designed to cut cleanly through glass, ceramic tile, porcelain, rock slab, granite, and other hard stone surfaces. The precision tip geometry helps minimize chipping and cracking during drilling.
Q: How many pieces are included in the A02F drill bit set?
A: The A02F set includes 30 pieces, offering a range of sizes — including 6mm — so you have the right bit on hand for a variety of glass, tile, and stone drilling applications.
Q: Do I need a special drill to use these bits?
A: No special drill is required. These bits are compatible with standard power drills and drill presses that accept a round shank bit. For best results when drilling glass or tile, use a low to moderate speed setting and apply light, consistent pressure. Using water as a coolant is also recommended to extend bit life.
Q: What makes the eccentric triangle tip design different from standard drill bits?
A: The eccentric triangle tip creates multiple cutting edges that reduce friction and help the bit self-center on hard, smooth surfaces like glass and tile. This results in cleaner, more accurate holes compared to conventional round or flat drill bits on these tough materials.
