Drill Bit Verto 60H840

The Verto 60H840 drill bit set contains eight diamond-coated bits with diameters 4, 5, 6, 7, 8, 10 and 12 mm plus a guide with a suction cup, designed for precision wet drilling of hard surfaces. The set weighs approximately 136 g and is intended for clean, accurate holes in ceramic tiles, glass, stoneware, terracotta and natural stone. The guide stabilizes the bit at the start of drilling and the diamond cutting surface provides durability and consistent performance when used with water cooling.

Advantages

This Verto set offers diamond-coated tips for extended life and precise cutting on hard materials. The included guide with suction cup improves drilling accuracy and reduces bit walking at startup. Compact set composition and lightweight construction make it easy to transport and store, while wet drilling capability helps prevent overheating and reduces chipping on brittle surfaces.

Suitable for

• Drilling holes in ceramic tiles and porcelain
• Working with glass and glazed surfaces
• Creating openings in terracotta and stoneware
• Drilling small holes in natural stone for fixtures or anchors
• Precision tasks in renovation, tiling and sanitary installations

Key specifications

• Bit diameters: 4, 5, 6, 7, 8, 10, 12 mm
• Coating: diamond cutting surface for wet drilling
• Set contents: 7 drill bits and 1 guide with suction cup (8 pieces total)
• Typical weight (set): approx. 136 g
• Intended use: wet drilling of hard, brittle materials

How to use

Mount the chosen diamond drill bit in a compatible rotary tool or drill with variable speed and fit the guide onto the work surface using the suction cup to hold it in place. Apply a steady low to medium speed and keep the drill perpendicular to the surface. Use a continuous supply of water to cool the bit and flush away debris; move the bit gently without excessive pressure to avoid cracking fragile materials. Stop periodically to check progress and maintain water flow.

Usage recommendations

Use with a drill that supports low-speed operation and water cooling. Secure the workpiece and wear appropriate eye and hand protection. Start with a small pilot contact angle and let the diamond grit cut the material—do not force the bit. For glazing or tempered glass, verify material suitability before drilling.
