Spiral cutting drill bit KWB 511475 1.5 cm diameter

Spiral cutting drill bit KWB 511475 with a 1.5 cm diameter is an industrial-quality wood bit designed for accurate, break-out free holes in soft and hardwoods. The bit features a centre point and shoulder cutter and a round shank for secure mounting. Its chemical black finish and ground, two-phase spiral geometry promote concentric running and long-lasting performance.

Advantages

The two-phase spirals provide concentric running and improved chip evacuation, while the centre point and shoulder cutter produce precise hole positioning and clean break-out free exits. The ground spirals and chemical black surface treatment increase wear resistance and maintain cutting accuracy during repetitive use. The round shank ensures compatibility with standard chucks and holders.

Suitable for

• Drilling precise holes in softwoods
• Drilling precise holes in hardwoods
• Carpentry and joinery tasks requiring clean hole exits
• Professional and DIY woodworking projects

Key specifications

• Manufacturer number (MPN): 511475
• EAN: 4009315114750
• Diameter: 1.5 cm

How to use

Secure the round shank in a compatible drill chuck. Mark the drilling position and, if required, clamp the workpiece to prevent movement. Start drilling at low speed to engage the centre point, then increase speed as appropriate for the wood type. Apply steady, even pressure and allow the spirals to evacuate chips; withdraw occasionally for deep holes to clear debris and avoid overheating.

Usage recommendations

For best results, use appropriate drill speeds for the wood species (lower speeds for hardwoods), keep the bit sharp and clean, and store in a dry place to protect the chemical black finish. Replace the bit when wear affects hole quality.
