Spiral cutting drill bit Makita D-33906

The Makita D-33906 spiral cutting drill bit is a precision tool designed for accurate drilling tasks. With a diameter of 1.4 cm, this drill bit delivers clean, consistent holes and is engineered for reliable performance across a range of common materials. Its spiral cutting geometry promotes efficient chip removal and stable cutting action, making it suitable for repeated use in workshop and on-site environments.

Advantages

The spiral cutting profile reduces clogging and improves drilling speed while maintaining hole quality. Constructed from wear-resistant material, the bit offers durability and retains cutting performance over extended use. Its consistent diameter and balanced design reduce wobble and contribute to straight, accurate holes.

Suitable for

• Drilling holes in wood and soft plastics
• General-purpose workshop and construction tasks
• Precision DIY projects requiring clean, consistent holes

Key specifications

• Diameter: 1.4 cm
• Cutting geometry: spiral/fluted design for chip evacuation
• Intended use: general-purpose drilling for wood and similar materials
• Compatibility: standard drill chucks that accept the bit shank

How to use

Secure the drill bit in a compatible drill chuck, ensuring it is tightened and centred. Select an appropriate rotational speed for the material being drilled—moderate speeds for wood and lower speeds if drilling plastics to avoid melting. Apply steady, even pressure and allow the spiral flutes to carry chips away from the cutting edge. Withdraw the bit periodically on deeper holes to clear debris and reduce heat build-up.

Usage recommendations

For best results, use the bit with a drill that provides stable rotational speed and minimal runout. When drilling hardwoods or abrasive materials, monitor the bit for wear and replace it if cutting performance degrades. Use personal protective equipment, such as safety glasses and gloves, and clamp workpieces securely before drilling.
