Diamond drill bit Cimco 208796

The Cimco 208796 diamond drill bit is a single-piece tool designed for precision drilling with a working diameter of 8.2 cm. Built for professional and skilled users, this diamond-coated drill bit offers consistent performance across a variety of hard and brittle materials. The construction emphasizes durability and accurate hole making while minimizing chipping and uneven edges.

Advantages

The diamond coating provides enhanced cutting performance and extended service life compared with conventional carbide bits. As a single-piece design, the drill bit maintains concentricity and stability during high-speed rotation, resulting in clean, accurate holes. The tool is engineered to reduce heat buildup and wear when used with proper cooling, which helps preserve the cutting edge and maintain consistent drilling quality over time.

Suitable for

• Drilling through ceramics, porcelain and tiles
• Cutting holes in glass and mirrors
• Working with natural and engineered stone
• Precision drilling in construction and renovation tasks

Key specifications

• Tool type: diamond-coated drill bit
• Working diameter: 8.2 cm
• Construction: single-piece design for stability
• Intended use: wet or cooled drilling to maximize tool life
• Typical applications: hard, brittle and abrasive materials

How to use

Secure the workpiece and mark the drilling point. For best results use low to moderate spindle speed and apply steady, even pressure while keeping the drill bit cooled with water or a suitable coolant. Begin drilling at a slight angle to establish a starting groove, then gradually straighten the drill to a vertical position. Periodically withdraw the bit to clear debris and restore coolant flow to the cutting surface. Follow the machine and safety instructions of your drill or core-drilling system.

Usage recommendations

Use continuous cooling during operation, avoid excessive axial force, and allow the bit to run freely without side loading. Replace the bit if signs of significant wear or irregular cutting appear to maintain hole quality and safety.
