Drill bit Bosch 4 mm diameter 2608522517 for metal and wood

Bosch drill bit 4 mm diameter 2608522517 is a replacement accessory designed for accurate drilling in metal and wood. The bit is intended for use with standard chucks on handheld drills and drill drivers, providing a compact 4 mm cutting diameter for tasks that require precise hole sizes. Its design prioritizes straightforward installation and reliable performance for workshop, DIY and repair applications.

Advantages

The drill bit delivers consistent 4 mm hole diameter and stable centering for repeatable drilling results. Manufactured to Bosch quality standards, it offers durability under normal workshop and household use. Compatibility with standard chucks enables quick changeovers between bits, while its geometry supports efficient chip removal when cutting into wood and many types of metal.

Suitable for

• Shank type: cylindrical shank suitable for standard chucks
• Typical applications: drilling, pilot hole creation, through-holes
• Manufacturing quality: Bosch production standards for workshop accessories

How to use

Secure the drill bit in the drill chuck and tighten the chuck firmly to prevent slippage. Select an appropriate rotational speed: lower speeds for metal and higher speeds for wood, adjusting feed pressure to maintain stable cutting without forcing the bit. For metal work, use cutting lubricant or coolant when drilling thicker or harder metals to reduce heat and wear. Retract the bit periodically to clear chips and prevent clogging when drilling deeper holes.

Recommendations

Wear appropriate eye protection and gloves when drilling. Match drill speed and feed rate to the material and thickness being drilled, and inspect the bit for wear before use. Replace the bit if it becomes dull, bent, or chipped to maintain hole accuracy and safe operation.
