Spiral cutting drill bit Makita Nemesis B-19906

The Makita Nemesis Spiral Cutting Drill Bit B-19906 is a precision spiral drill designed for accurate, clean drilling with a diameter of 1.2 cm. Built for professional and DIY use, the bit combines a spiral cutting geometry with robust material construction to deliver steady cutting performance across a range of common materials. The compact diameter and spiral flute design promote efficient chip evacuation and reduced clogging during operation.

Advantages

This spiral cutting drill bit provides consistent hole quality with minimal burring and reduced need for secondary finishing. Its spiral geometry improves chip removal and reduces heat buildup, which contributes to longer tool life and stable performance during prolonged use. The bit's solid construction resists wear and maintains cutting accuracy over multiple uses.

Suitable for

• Drilling precise holes in wood
• Working with soft metals such as aluminum
• Plastic and composite material drilling
• General-purpose workshop and on-site drilling tasks

Key specifications

• Diameter: 1.2 cm
• Type: Spiral cutting drill bit
• Design: Spiral flute for efficient chip evacuation
• Intended use: Precision drilling in a variety of materials
• Compatibility: Standard handheld and drill-press tools compatible with straight-shank drill bits

How to use

Secure the workpiece and select an appropriate drill speed for the material being drilled. Install the spiral cutting drill bit in the drill chuck and tighten securely. Begin drilling with steady pressure, allowing the spiral flutes to evacuate chips; avoid excessive force to prevent bit deflection. Withdraw the bit occasionally for deep holes to clear chips and reduce heat buildup. After use, clean chips from the flutes and store the bit in a dry place to prevent corrosion.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses and gloves. Match drill speed and feed to the material: lower speeds for metals, higher speeds for wood and plastics. For repeated precision work, inspect the cutting edges regularly and replace the bit when signs of wear affect hole quality.
