Starting Clean: Precision Drilling for Fragile Surfaces

The Rockhard Precision Glass and Tile Drill Bit is the ideal solution for clean, chip-free hole starting in brittle materials. Engineered for smooth operation, this bit is perfect for all grades of ceramic tile, porcelain, and glass, where precision is paramount.

Designed exclusively for controlled, clean hole drilling, this bit must be used in Rotation Mode ONLY to prevent material breakage.

Key Features for Flawless Results:

"No-Walk" Start: Features a meticulously sharpened ogival point that allows for a precise hole to be started immediately upon contact, eliminating the frustrating "walking" and wandering often associated with standard bits.
Progressive Diameter Control: The unique "Aspic Tongue" shape allows the operator to progressively determine the desired hole diameter, ensuring full control and preventing shattering on the final cut.
Flexible Use: Can be used under Rotation Mode ONLY either with or without water. Note: Using water can prolong bit life and provide a cleaner cut on hard ceramics.
Clean & Accurate: Provides smooth, reliable results in the most challenging and visually exposed materials.
