Bosch 2 609 255 214 drill bit Diamond drill bit 5 pc(s)

The Bosch 2 609 255 214 drill bit set contains five diamond drill bits designed for drilling tasks in wood. Supplied in a hanging box for convenient storage and transport, the set includes five sizes to cover a range of hole diameters. Each bit features a cylindrical shank and a black finish, allowing compatibility with standard chucks and providing a uniform appearance across sizes.

Advantages

Diamond-tipped cutting edges provide enhanced wear resistance compared with conventional high-speed steel bits when working on abrasive or composite wood materials. The cylindrical shank ensures secure gripping in most drills and drill presses. The set of five sizes gives straightforward selection for different hole diameters without the need to change tool types. The hanging box keeps the bits organized and protected when not in use.

Suitable for

• Drilling clean holes in wood and wood-based materials
• General woodworking and carpentry tasks
• Preparing holes for dowels, fittings or cable passages
• Workshop and on-site repair jobs requiring multiple hole sizes

How to use

Select the drill bit size appropriate for the required hole diameter, insert the cylindrical shank into the drill chuck and tighten securely. Use a steady feed rate and consistent pressure appropriate for the wood species you are working with. For through-holes, drill straight and maintain alignment; for clean edge holes, consider backing the workpiece on scrap material to reduce splintering. Withdraw the bit periodically to clear chips and prevent overheating when drilling thicker sections.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. Match drill speed to bit size and material hardness — lower speeds for larger diameters or dense hardwoods. Avoid excessive lateral force to preserve the diamond cutting surface and extend bit life. Store the set in its hanging box to protect cutting edges and prevent corrosion.
