Drill bit Bosch 4 mm Ø, 50 mm length, model 2608000695

Straight shank Bosch drill bit with a 4 mm cutting diameter and 50 mm overall length, designed for precise hole making in metal, wood and plastics when used with compatible drills. The tool is intended for routine workshop and DIY tasks where accurate, repeatable holes are required for assembly, repair and fabrication work. The solid construction and standard shank allow use in hand drills, drill presses and cordless drivers that accept straight shanks of this size.

Advantages

The Bosch 4 mm, 50 mm drill bit provides consistent hole diameter and reliable penetration across common materials. Its straight shank fits standard chucks for secure mounting and stable rotation. The specified length balances reach and rigidity to reduce wobble while enabling through-holes or partial-depth holes in panels and components. Manufactured to Bosch quality standards, the bit offers even cutting performance and predictable chip removal when used at recommended speeds and with appropriate lubrication on metals.

Suitable for

• Drilling small-diameter holes in sheet metal and light structural steel
• Creating pilot or clearance holes in wood for screws and dowels
• Making holes in plastic components for fasteners or cable passage
• General workshop tasks, repairs and light fabrication

Key specifications

• Cutting diameter: 4 mm
• Overall length: 50 mm
• Shank type: straight shank for standard chucks
• Suitable materials: metal, wood, plastics
• Typical applications: through-holes and partial-depth holes

How to use

Select a compatible drill or driver with a chuck that securely grips a straight shank. Mark the drilling point and, if needed, use a center punch on metal to prevent walking. Start at a low to medium speed appropriate for the material, apply steady axial pressure and allow the bit to cut without excessive force. For metal drilling, use cutting fluid or lubricant to extend bit life and improve chip evacuation. Withdraw the bit periodically to clear chips when drilling deeper holes.

Usage recommendations

Use recommended drill speeds and appropriate lubrication for metal work. Clamp workpieces securely and wear eye protection. Replace the bit when wear reduces cutting performance or when the diameter tolerance is critical for the final assembly.
