Spiral cutting drill bit Makita D-34067

The Makita D-34067 spiral cutting drill bit is a single-piece metalworking tool with a 2.8 cm diameter designed for precise, clean drilling. Built for straight, efficient chip evacuation during cutting, this drill bit is suitable for a range of drilling tasks where a smooth hole finish and dimensional accuracy are required. Its construction supports repeated use in workshop and on-site conditions while maintaining stable performance when matched with compatible drill chucks and appropriate speeds.

Advantages

The spiral cutting geometry promotes efficient chip removal and reduces clogging, which helps maintain cutting speed and hole quality. The single-piece design improves rigidity and reduces the risk of breakage under normal operating conditions. Precision ground cutting edges provide stable centring and consistent hole diameters. The tool is compatible with standard drill holders and can be used with a variety of rotary power tools when correct mounting and speed settings are observed.

Suitable for

• Drilling clean holes in metal and other rigid materials
• Workshop production tasks requiring repeatable hole quality
• Professional repair and maintenance jobs
• DIY projects where a durable, easy-to-use drill bit is needed

Key specifications

• Type: spiral cutting drill bit, single-piece construction
• Diameter: 2.8 cm
• Material compatibility: suitable for metal and other rigid materials (see tool and material guidelines)
• Geometry: spiral/fluted design for chip evacuation
• Mounting: designed for standard drill chucks

How to use

Select a drill or drill press with a compatible chuck and secure the bit firmly. Choose a rotational speed appropriate to the material being drilled — lower speeds for harder metals and higher speeds for softer materials — and apply steady, moderate feed pressure. Use cutting fluid for metal drilling to reduce heat and improve tool life. Retract the bit periodically when drilling deep holes to clear chips and avoid clogging. After use, clean chips from the flutes and store the bit in a suitable holder to protect the cutting edges.

Usage recommendations

For best results, match drill speed and feed to the material, use cutting fluid on metal, and avoid excessive side loads. Inspect the cutting edges before use and replace the bit if the edges are chipped or excessively worn to maintain hole quality and reduce the risk of breakage.
