Drill Bit Festool D 4-NL 11 HW-DF 500 Diameter 4mm Length 1.1cm

The Festool D 4-NL 11 HW-DF 500 drill bit is a 4 mm diameter, 11 mm working-length carbide-tipped bit designed for precise drilling in woodworking and related joinery tasks. Developed to deliver consistent hole quality and long service life, this bit complements Festool DOMINO joining systems and other precision tools used in furniture making and carpentry.

Advantages

This 4 mm Festool drill bit offers accurate centring and clean chip removal thanks to its carbide tip geometry and optimised flute design. The short 11 mm working length reduces vibration for improved hole precision and repeatability. Manufactured to Festool quality standards, the bit provides reliable performance and extended durability under normal woodworking conditions.

Suitable for

• Precision drilling for DOMINO joinery and mortise preparation
• Furniture making and cabinet assembly
• Carpentry tasks requiring small-diameter, accurate holes
• Use with compatible drill and routing systems that accept 4 mm bits

How to use

Mount the D 4-NL 11 HW-DF 500 securely in a compatible chuck or collet, ensuring the flutes are oriented for correct chip evacuation.

Retract the bit periodically on deep operations to clear chips and avoid heat build-up.

Usage recommendations

Use appropriate personal protective equipment and select drilling speeds compatible with the material. Clean and inspect the bit after use; replace if the carbide tip shows wear or chipping to maintain hole quality and prevent damage to the workpiece.
