Key Features
- Eccentric Design: The unique off-center geometry keeps the bit firmly on target for accurate, slip-free starts — no pilot hole required.
- Four-Flute Cutting Edges: Sharp, multi-flute construction enables fast material removal and smooth hole formation in hard surfaces.
- Triangular Spiral Body: Reduces vibration during operation, resulting in cleaner holes and improved stability throughout the drill stroke.
- Carbide / Steel Alloy Construction: Resists wear, maintains sharpness longer, and delivers consistent performance job after job.
- Wide Compatibility: Works on glass tile, ceramic tile, concrete, granite, hard plastic, cement, and wood. Pairs exceptionally well with a water drill for optimal results.
- Multiple Size Options: Available in 6 mm, 8 mm, 10 mm, and 12 mm to suit a wide range of drilling tasks.

Frequently Asked Questions
Q: What materials can this four-flute eccentric drill bit cut through?
A: This carbide drill bit is designed to handle a wide range of hard materials, including glass tile, ceramic tile, concrete, granite, cement, hard plastic, and wood. For best results on very hard surfaces such as granite or thick ceramic, use it in conjunction with a water drill to keep the bit cool and improve cutting efficiency.
Q: What sizes are available, and how do I choose the right one?
A: The bit is available in four sizes: 6 mm, 8 mm, 10 mm, and 12 mm. Choose the size that matches the diameter of the hole you need — for example, a 6 mm bit is ideal for small anchor points, while a 12 mm bit suits larger fixtures such as towel bars or shelf brackets mounted to tile.
Q: Does the eccentric design prevent the bit from slipping on smooth tile or glass?
A: Yes. The eccentric (off-center) geometry of the bit helps it bite into smooth, hard surfaces right from the start, minimizing skidding without the need to score the surface first. The triangular spiral body further stabilizes the bit during drilling to produce clean, precise holes.
Q: Is this drill bit compatible with standard electric drills?
A: This drill bit features a standard round shank compatible with most electric drills and drill presses. For the cleanest results, use a low-to-medium speed setting and, where possible, apply water cooling when drilling glass or very hard tile.
