Brad point drill bit KWB 511810 1 cm diameter 1 pc

The KWB 511810 brad point drill bit is an extra-long wood drilling tool with a 10 mm (1 cm) diameter and 250 mm overall length, designed for precise, break-out-free holes in beams and other wooden components. Made from CrV steel with a single spiral and chemical black finish, it features a centre point and two cutting wings for accurate guidance and clean chip removal. The bit is suitable for both softwoods and hardwoods and is supplied as a single piece for industrial-quality woodworking tasks.

Advantages

This extra-long wood drill offers accurate centring thanks to the brad point and centre tip, reduced breakout at the exit side because of the cutting wings, and reliable strength from chromium-vanadium (CrV) steel. The single-spiral design supports consistent chip evacuation along the 250 mm length, while the chamfer-ground edges improve cutting performance and hole quality. The chemical black finish increases corrosion resistance and reduces glare during use.

Suitable for

• Drilling deep, clean holes in beams and thick timber
• Joinery and structural woodworking where breakout-free exits are required
• Softwood and hardwood drilling tasks
• Use with handheld drills and drill presses for long-reach holes

How to use

Mark the drilling point on the workpiece and secure the beam or timber to prevent movement. Fit the KWB 511810 10 mm brad point drill into a suitable chuck and tighten firmly. Start drilling at low speed to let the centre point engage, then increase speed steadily while applying moderate, even pressure. Withdraw the bit occasionally on deep holes to clear chips and avoid overheating. For best results use appropriate feed rate and coolant/lubrication if recommended for the timber type or machine.

Usage recommendations

Use proper personal protective equipment, clamp workpieces securely, and avoid excessive side load on the bit. Inspect the drill bit before use and replace when cutting edges become dull to maintain hole quality and safety.
