Diamond drill bit Yato YT-60423 8 mm 1 pc

The Yato YT-60423 8 mm diamond drill bit is designed for precise drilling in hard materials such as ceramic, porcelain, glass and stone. Supplied as a single piece, this 8 mm drill bit offers a compact, rigid cutting tip that enables controlled material removal and helps produce clean, accurate holes with minimal chipping when used with appropriate technique and equipment.

Advantages

This diamond drill bit provides consistent cutting performance and extended wear life when used on abrasive and brittle materials. Its diamond-embedded working tip maintains sharpness longer than conventional carbide bits on hard surfaces, while the single-piece supply makes replacement simple and predictable for one-off tasks or targeted repairs. The 8 mm diameter offers a balance between hole size and structural strength, suitable for medium-diameter drilling where precision is required.

Suitable for

• Drilling holes in ceramic and porcelain tiles for plumbing fixtures and fittings
• Creating openings in glass panels and mirrors for mounting hardware
• Working on natural and engineered stone for countertops, backsplashes and decorative elements
• Small repair and installation tasks that require a single, durable drill bit

Key specifications

• Cutting diameter: 8 mm
• Tip type: diamond-impregnated
• Quantity: 1 piece
• Intended materials: ceramic, porcelain, glass, natural stone, engineered stone
• Recommended use: wet drilling to reduce heat and prolong tool life

How to use

Mark the drilling location and secure the workpiece to prevent movement. Use a drill press or a hand drill with a suitable chuck, keeping the drill at a low to moderate speed. Start drilling at a shallow angle or use a guide to establish the initial contact point, then bring the drill to a perpendicular position and apply light, steady pressure. For most hard and brittle materials, supply a steady stream of water to the cutting area to cool the bit, reduce dust, and extend the bit's life. Withdraw the bit occasionally to clear debris and maintain cooling.

Usage recommendations

Use personal protective equipment such as safety glasses and gloves. Avoid excessive force or high speed; allow the diamond tip to cut gradually. When drilling glass or tiles, support the back side of the material and use continuous water flow to prevent cracking and overheating.
