Bosch 2 608 833 812 broca martelo 1 unid.

Bosch 8 mm drill bit model 2608833812 is a single straight shank bit designed for general-purpose drilling where an 8 mm hole is required. The bit is compatible with standard chucks that accept cylindrical shank bits of this diameter and is intended for workshop and home use. Its geometry is engineered to provide accurate hole diameter and stable drilling performance in common materials.

Advantages

The drill bit offers precise diameter control and consistent concentricity, which helps produce clean, accurate holes. Manufactured with attention to material hardness and edge geometry, it provides reliable cutting performance and reasonable wear resistance for general drilling tasks. Its standard 8 mm cylindrical shank allows quick fitting in most drill chucks and ensures straightforward use across a variety of handheld and bench drills.

Suitable for

• Drilling 8 mm holes in wood and soft plastics
• General metalworking tasks on thin sheets and non-hardened metals
• Workshop and home repair projects requiring precise hole sizes
• Use with handheld drills and drill presses accepting cylindrical shanks

Key specifications

• Nominal diameter: 8 mm
• Shank type: cylindrical straight shank suitable for standard chucks
• Intended use: general-purpose drilling
• Typical compatible tool types: handheld electric drills, cordless drills, drill presses
• Material suitability: wood, plastics, and common non-hardened metals (subject to bit material and finish)

How to use

Secure the drill bit in the chuck of a compatible drill and tighten the chuck according to the drill manufacturer's instructions. Select a drilling speed appropriate for the material: lower speeds for metals, higher speeds for wood and plastics. Use steady, moderate feed pressure and allow the bit to cut without excessive force. For metalwork, use cutting fluid or lubricant where applicable to reduce heat and prolong bit life. Periodically withdraw the bit to clear chips and maintain efficient cutting.

Recommendations

Inspect the bit for wear or damage before use. Match drilling speed and feed to the material being worked to optimize hole quality and extend service life. Store the bit in a dry place and avoid overheating during use to preserve hardness and cutting edge integrity.
