Spiral cutting drill bit Makita D-33875

The Makita D-33875 spiral cutting drill bit is a 12 mm diameter tool designed for precision drilling and clean spiral cutting action. Engineered for accurate hole creation, the bit provides consistent performance across a range of materials and is supplied as a single piece for straightforward replacement and storage. Its spiral flute design helps evacuate chips efficiently while maintaining stable drilling progress.

Advantages

The spiral geometry promotes fast chip removal and reduces clogging, which helps maintain cutting efficiency and prolongs tool life. A precisely ground cutting edge delivers clean entry and exit holes with minimal tear-out. The 12 mm diameter offers a balance between rigidity and versatility, suitable for many general-purpose drilling tasks. Sold individually, the bit is convenient to carry and replace in a professional or home toolkit.

Suitable for

• Drilling holes in wood and engineered wood products
• Drilling in plastics and non-ferrous materials
• Light to medium-duty construction and repair tasks
• DIY projects and workshop tasks requiring clean, precise holes

Key specifications

• Diameter: 12 mm
• Cut type: spiral cutting geometry
• Package quantity: 1 piece
• Intended use: precision drilling and clean cuts

How to use

Clamp the workpiece securely and select an appropriate drill speed for the material being drilled. Fit the spiral cutting drill bit in the drill chuck and ensure it is tightened. Start drilling at moderate speed and apply steady, even pressure; allow the spiral flutes to evacuate chips and avoid forcing the bit. Retract occasionally on deeper holes to clear chips and reduce heat build-up. After use, clean chips 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 drilling speed and feed to the material; lower speeds for dense materials and higher speeds for softer materials. For maximum accuracy, pilot or center the hole before using the 12 mm bit on thin or brittle materials.
