GLASS DRILL BIT SET ROSSEL 9715 (5PCS/SET) (25 SETS/PKT) (100SETS/CTN)

Product Description

The Rossel Glass Drill Bit Set 9715 is a diamond‑coated drill bit set designed for drilling holes in glass, ceramic tiles, porcelain and similar brittle materials using a standard electric drill. These bits use a diamond grit cutting edge that grinds rather than cuts, allowing you to create neat, precise holes in hard surfaces that would crack with regular twist bits. This set is ideal for installations such as taps, fixtures, shelving, mirrors and tile‑mounted accessories in bathrooms and kitchens.

Key Benefits and Features

• Diamond‑coated cutting surfaces — Abrasive diamond grit is electroplated onto the bit edges to grind through hard, brittle materials with reduced chipping.
• Wet drilling recommended — Use with water as a coolant to extend bit life and reduce heat buildup while drilling glass or tile.
• Works with standard drills — Fits most keyed or keyless drill chucks; no special adapter needed.
• Efficient chip and water flow — Sets typically include side holes or slots around each bit to help water reach the cutting surface and allow debris to escape.
• Clean, precise holes — Designed to produce smooth hole edges in brittle surfaces like glass and ceramic with minimal breakage when used correctly.

Usage Tips for Best Results

• Keep water on the bit and material throughout drilling to cool the diamond surface and reduce risk of cracking the glass or tile.
• Start drilling at a slow speed and hold the drill steady to avoid slips on slick surfaces.
• For tiles with glaze, begin at a slight angle until a small groove forms, then straighten the drill for a cleaner hole.
