Drill bit Bosch 7 mm x 100 mm, model 2 609 255 204, single piece

Bosch 7 mm x 100 mm drill bit (single piece) is a brad point wood drill designed for clean, tear-free drilling and precise hole placement. The centring tip and shoulder cutter ensure accurate starts and reduced splintering when working with soft and hard wood. The 100 mm overall length provides sufficient reach for through-holes and recessed drilling tasks in furniture making, carpentry and general woodworking.

Advantages

The brad point geometry with a centring tip provides accurate positioning and reduces walking on the workpiece surface. The shoulder cutter trims the wood fibers at the hole edge to deliver clean, square hole rims without tearing. Manufactured to Bosch factory standards, the bit offers consistent dimensions and reliable cutting performance in wood applications. Supplied as a single piece, it is ready for immediate use in hand-held and bench drills.

Suitable for

• Precise drilling of softwood and hardwood
• Furniture assembly and joinery
• Installing dowels, plugs or screws where accurate hole diameter is required
• Through-holes and recessed holes in carpentry projects

Key specifications

• Diameter: 7 mm
• Overall length: 100 mm
• Tip type: Brad point with centring tip
• Cutter: Shoulder cutter for clean hole edges
• Material compatibility: Softwood and hardwood
• Quantity: 1 piece

How to use

Select a drill or drill press with a compatible 7 mm chuck and secure the bit firmly in the chuck. Mark the drilling position and, if necessary, clamp the workpiece to prevent movement. Start drilling at low speed to engage the centring tip, then increase speed as the bit cuts. Apply steady, moderate pressure and clear chips periodically to avoid clogging. For through-holes, support the workpiece underside or finish the exit side to reduce tear-out.

Usage recommendations

Use the bit primarily for woodworking; avoid using the brad point bit in masonry, metal, or other non-wood materials. Keep the cutting edges sharp and store the bit dry to maintain performance. For best results in hardwood, use controlled feed and appropriate drill speed to prevent overheating and burning of the wood.
