Spiral cutting drill bit Makita D-33934

The Makita D-33934 spiral cutting drill bit with a 1.6 cm diameter is engineered for precision hole-making in a variety of materials. Its spiral cutting geometry promotes efficient chip evacuation and consistent cutting action, resulting in clean-edged holes and reduced risk of material damage. Supplied as a single piece, the bit fits standard drill chucks and is suitable for repeated use in both workshop and field environments.

Advantages

The spiral flute design ensures faster chip removal and stable drilling, while the hardened cutting edge maintains sharpness for repeated use. Its 1.6 cm diameter provides a balance between control and material removal rate, making it practical for both delicate and heavier tasks. The bit’s construction offers improved durability and reduces vibration during operation, contributing to more accurate hole placement.

Suitable for

• Drilling precise holes in wood
• Working with composite materials and plastics
• General-purpose drilling in light metals
• DIY projects and professional repair tasks

Key specifications

• Diameter: 1.6 cm
• Type: spiral cutting drill bit
• Quantity: single piece
• Compatibility: standard drill chucks (handheld and stationary drills)
• Design features: spiral flute for chip evacuation, hardened cutting edge

How to use

Secure the Makita spiral cutting drill bit firmly in the drill chuck and tighten according to the drill manufacturer’s instructions. Select an appropriate drilling speed based on the material: lower speeds for metals and harder composites, medium to higher speeds for wood and plastics. Apply steady pressure and allow the bit to cut without forcing; withdraw periodically when drilling deeper holes to clear chips and reduce heat buildup. After use, clean chips from the flutes and store the bit in a protective case to preserve the cutting edge.

Usage recommendations

Use appropriate personal protective equipment (safety glasses and gloves) and clamp workpieces securely. Match drilling speed to material hardness and avoid excessive side load to prolong the bit’s life. For prolonged accuracy, sharpen or replace the bit when signs of dulling or chipping appear.
