Frequently Asked Questions

Q: What materials can these tungsten carbide eccentric drill bits cut through?

A: These drill bits are designed for glass, ceramic tile, porcelain tile, wall tile, and concrete/masonry surfaces. The tungsten carbide tip and eccentric head make them especially effective on hard, smooth surfaces that standard twist bits struggle with.

Q: What makes the eccentric (oblique) head design better for tile and glass drilling?

A: The off-center eccentric tip creates a self-locating action on slick surfaces, preventing the bit from wandering when you begin drilling. This results in cleaner, more accurate holes in glass and glazed tiles without the need for a pilot punch or tape guide.

Q: Do these bits require a hammer drill or a standard drill?

A: For glass and ceramic tile, use a standard variable-speed drill — avoid hammer mode, as the percussion action can crack delicate surfaces. For concrete and masonry, a hammer drill may be used with appropriate settings.

Q: What is the length and shank size of these drill bits?

A: Each bit measures 90mm in length. They feature a standard round shank compatible with most conventional drill chucks. Always verify your drill's chuck compatibility before use.
