Drill bit Bosch 8 mm × 100 mm, model 2608833780, straight shank, metal drilling

Bosch 8 mm × 100 mm drill bit (straight shank) is designed for precise metal drilling where a consistent 8 mm hole is required. The tool has a 100 mm overall length to reach deeper workpieces while maintaining stability in the chuck. Its straight shank fits standard three-jaw chucks and compatible hand drills or drill presses used in general metalworking tasks.

Advantages

The drill bit provides consistent hole diameter and reliable concentricity for repetitive metal drilling tasks. A straight shank ensures easy installation and firm grip in most drill chucks. Its length enables access to deeper sections without compromising rigidity, and the geometry of the cutting tip supports controlled penetration and chip evacuation when used at appropriate speeds and with correct lubrication.

Suitable for

• Drilling through thin and medium-thickness metal sheets
• Creating 8 mm clearance or pilot holes for fasteners and bolts
• Use in hand drills and drill presses for workshop or maintenance tasks
• Metal fabrication, repair and assembly operations requiring precise 8 mm holes

Key specifications

• Diameter: 8 mm
• Overall length: 100 mm
• Shank type: straight shank
• Material application: metal drilling
• Compatibility: standard three-jaw chucks, compatible hand drills and drill presses

How to use

Secure the workpiece and mark the drilling point. Install the straight shank of the 8 mm drill bit firmly in the chuck and tighten according to the drill manufacturer's recommendations. Select an appropriate rotational speed for the metal being drilled, apply cutting fluid if needed, and start drilling with steady pressure. Retract periodically to clear chips and prevent overheating, and complete the hole with a consistent feed to maintain the 8 mm diameter and clean edge.

Recommendations

The drill bit performs best when used with proper cutting speed, adequate clamping of the workpiece, and suitable lubrication or coolant for metal cutting. Replace the bit if wear or chipping affects hole quality, and inspect the shank and cutting edges before each use to ensure safe and accurate operation.
