Spiral cutting drill bit Makita D-33962

The Makita D-33962 spiral cutting drill bit is a precision tool designed for controlled drilling with a diameter of 1.8 cm. Constructed from durable materials and finished to provide clean chip evacuation, this spiral cutting bit is intended for general-purpose use across a range of common workshop and construction materials. It fits standard chucks and can be used with corded and cordless drills where a larger-diameter spiral bit is required.

Advantages

This spiral cutting drill bit delivers consistent hole quality and efficient cutting thanks to its helical flute design that aids chip removal and reduces clogging. The robust construction improves wear resistance and extends service life under normal working conditions. The bit’s geometry supports stable drilling and reduces wandering at the start of the cut, enabling more accurate positioning and cleaner edges around the drilled hole.

Suitable for (tasks / use cases)

• Drilling larger-diameter holes in wood, composite panels, and similar soft-to-medium density materials
• Create entry and clearance holes for fasteners and dowels
• Workshop tasks requiring repeatable clean cuts and reliable chip evacuation
• General repair, renovation, and DIY applications where a 1.8 cm spiral bit is needed

Key specifications

• Diameter: 1.8 cm
• Type: spiral cutting drill bit (helical flute)
• Material compatibility: wood and composite materials; suitable for soft-to-medium density substrates
• Shank: round shank compatible with standard drill chucks
• Design features: helical flute for chip removal and stable drilling

How to use

Secure the bit in the drill chuck and tighten firmly. Mark the drilling point and, if necessary, use a pilot mark or center punch to reduce walking. Start drilling at low speed to establish the hole, then increase speed as the bit engages the material. Apply steady, moderate pressure—avoid forcing the bit—to allow proper chip evacuation through the flutes. Withdraw periodically on deeper holes to clear chips and cool the cutting edge. After use, remove debris from the flutes and store the bit in a dry place.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. Match drill speed and feed pressure to the material being cut; lower speeds are recommended for harder or denser materials. Avoid excessive side loads and overheating to preserve cutting performance and extend tool life.
