Spiral cutting drill bit Makita D-34160

The Makita D-34160 spiral cutting drill bit is a 4 cm diameter tool designed for precision drilling tasks. Engineered to deliver clean, consistent holes, this drill bit is suitable for a range of materials where a spiral cutting geometry improves chip evacuation and surface finish. Its construction prioritizes durability and consistent performance for repeated use in workshop and on-site applications.

Advantages

The spiral cutting profile helps remove material efficiently, reducing clogging and heat buildup during drilling. A 4 cm diameter provides a larger bore for tasks that require wider holes while maintaining dimensional stability. The bit is built with materials and finishing that resist wear and preserve cutting edges under regular use, supporting longer service life and reduced need for frequent replacement.

Suitable for

• Drilling larger-diameter holes in wood and composite materials
• Creating openings for fittings, pipes or cable pass-throughs
• Workshop and construction tasks requiring controlled chip removal

Key specifications

• Diameter: 4 cm
• Cutting geometry: spiral/helix for chip evacuation
• Intended use: general purpose drilling in wood and composites
• Design focus: durable construction for repeated use

How to use

Select a drill or driver compatible with the drill bit diameter and secure the bit in the chuck according to the tool manufacturer's instructions. Mark the drilling position and, if needed, use a pilot hole or center punch for accurate placement. Start drilling at low speed to establish the hole, then increase speed while maintaining steady axial pressure. Withdraw the bit periodically in deep holes to clear chips, and allow the bit to cool if drilling continuously to prevent overheating.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and hearing protection. Match drill speed and feed rate to the material being drilled; lower speeds and steady pressure are generally preferable for larger-diameter bits. Store the bit in a dry place and inspect cutting edges before use to ensure safe and effective performance.
