DIAMOND GLASS DRILLING BIT ROSSEL 6MM 9617 (10PCS/SET) (40SET/PKT) (400SETS/CTN)

Product Description

The Rossel Diamond Glass Drill Bit 6 mm (9617) is a diamond‑electroplated hole saw‑style bit designed for drilling clean holes in glass, ceramic, tile and similar hard, brittle materials. The bit is built with a diamond‑coated cutting edge that grinds through hard surfaces rather than cutting like a standard twist bit. It’s typically used for installing fixtures, fittings or running cables through tiles and glass, and it can be used in most standard electric drills when used with proper technique and coolant.

Key Benefits and Features

• Diamond‑electroplated cutting edge: Provides abrasive strength to grind through glass, ceramic and tile without excessive chipping or cracking.
• Side clearance holes: Allows cooling water to reach the cutting surface and helps eject debris to keep drilling smoother.
• Wet drilling design: Works best with water cooling — water reduces heat and helps prevent the diamond surface from premature wear or glazing.
• Standard chuck compatibility: Fits in most handheld drills with a standard chuck — no special adapters required.
• Ideal for precision holes: Good choice for delicate materials where control and hole quality matter (e.g., glass tiles, shower screens, ceramic tiles).

Drilling Tips

• Go slow and steady — diamond bits don’t cut like wood/metal bits; they grind the material.
• Always use water to keep the bit cool and avoid cracking the glass or tile.
• Start the drill at a slight angle to “score” the surface before moving to perpendicular drilling for a cleaner hole.
