Drill bit Bosch 2608599051, diamond tip, 10 mm diameter, 66 mm length

Diamond drill bit Bosch 2608599051 with a 10 mm cutting diameter and 66 mm total length is designed for precise drilling in hard materials. The tip is diamond-coated to increase cutting performance and durability when working with brittle surfaces such as ceramic tiles, glass and certain types of natural and engineered stone. The compact 66 mm overall length and straight shank make it compatible with most handheld and bench drills that accept standard-diameter bits.

Advantages

The diamond tip provides a clean entry and reduced chipping on fragile materials, while the 10 mm cutting diameter allows for accurate hole sizes for anchors, fittings and plumbing penetrations. The bit’s construction increases lifespan compared with conventional carbide tips when used on abrasive or glass-like surfaces. Its stable shank and balanced geometry improve control and reduce walking at the start of drilling, supporting precise work in both professional and DIY environments.

Suitable for

• Drilling holes in ceramic and porcelain tiles
• Drilling through glass and glazed surfaces
• Creating precise openings in natural stone and engineered stone countertops
• Installing anchors, fixtures or plumbing through hard wall coverings

Key specifications

• Cutting diameter: 10 mm
• Total length: 66 mm
• Tip type: diamond-coated
• Shank type: straight round shank (standard drill chuck compatible)
• Intended materials: tile, glass, natural and engineered stone

How to use

Secure the drill bit in a compatible drill chuck ensuring the shank is fully inserted and tightened. Mark the drilling point on the workpiece and, if needed, use masking tape to reduce walking. Begin drilling at low speed with gentle pressure to establish the hole, then maintain steady moderate speed without excessive force. For glass, tiles and stone, use consistent cooling or periodic withdrawal to clear debris and reduce heat; for wet-drilling, follow drill manufacturer guidance about water supply. After completing the hole, stop the drill before removing the bit to avoid chipping the edge.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses and gloves. Match drilling speed and cooling method to the workpiece material: lower speeds and water cooling for glass and vitrified tiles; moderate speeds for softer stone. Avoid using the diamond tip on metal or wood. Inspect the bit before use and replace it when cutting performance declines to maintain hole quality.
