Spiral cutting drill bit Makita Nemesis 25 mm, 1 pc

Spiral cutting drill bit Makita Nemesis 25 mm is a single-piece bit designed for making clean 25 mm holes in wood and similar materials. The bit features a spiral cutting geometry that evacuates chips efficiently and reduces binding during drilling. It is intended as a replacement or spare for compatible drill models and for use in workshop and construction environments where a consistent 25 mm bore is required.

Advantages

The spiral cutting geometry provides continuous chip removal and stable cutting action, resulting in smoother holes and reduced effort for the operator. The 25 mm diameter offers a standard bore size for many joinery and installation tasks. The single-piece construction improves rigidity and helps maintain concentricity during use, while the design is suitable for repeated insertion and withdrawal without rapid wear.

Suitable for

• Drilling 25 mm holes in soft and hardwoods
• Door hardware and lock installation
• General carpentry and joinery tasks
• Workshop repair and assembly operations

Key specifications

• Diameter: 25 mm
• Geometry: spiral cutting flutes for chip evacuation
• Quantity: 1 piece
• Intended materials: wood and wood-based panels
• Shank type: compatible with standard drill chucks

How to use

Secure the drill bit in a compatible drill chuck and tighten firmly. Mark the drilling position and, where possible, use a guide or clamp the workpiece to prevent movement. Start drilling at low speed to establish the cut, then increase speed as the bit engages. Use steady pressure without forcing the bit; allow the spiral flutes to carry chips away. Withdraw the bit occasionally on deep holes to clear chips and prevent overheating. After use, clean debris from the flutes to maintain performance.

Usage recommendations

For best results, use the bit with drills that provide stable rotational speed and adequate torque. Match drilling speed to the type of wood—slower speeds for hardwoods, moderate speeds for softwoods—and avoid excessive side loads. Store the bit in a protective case or holder to prevent damage to the cutting edges.
