Twist drill bit Makita D-29670 5 mm 1 pc

The Makita D-29670 5 mm twist drill bit is a single-piece tool designed for precision drilling in a range of common materials. Manufactured to industry standards, this 5 mm bit fits standard drill chucks and is intended to deliver steady performance for both occasional DIY tasks and routine professional use. The compact size and single-piece construction aim to provide consistent hole quality and straightforward handling during drilling operations.

Advantages

This 5 mm twist drill bit offers accurate centring and a uniform flute design to remove chips efficiently while maintaining drill stability. The single-piece construction reduces the risk of separation and improves torsional strength under normal working loads. Compatible with standard electric and cordless drills, the bit is engineered to balance durability and cutting efficiency for general-purpose drilling.

Suitable for

• Drilling pilot holes for screws in wood and soft composites
• Creating small holes in metal sheets and non-hardened metals
• General-purpose holes in plastics and laminates
• Workshop and on-site maintenance tasks requiring a 5 mm aperture

Key specifications

• Typical materials: wood, plastics, non-hardened metals, composites

How to use

Secure the twist drill bit in a drill chuck, ensuring it is properly centered and tightened. Select a drilling speed appropriate to the material being worked—lower speeds for metals and higher speeds for wood and plastics—and apply steady, even pressure without forcing the bit. Periodically withdraw the bit to clear chips and reduce heat buildup. For harder materials or prolonged use, use cooling or lubrication as appropriate and check the bit for wear before continued operation.

Usage recommendations

Wear appropriate eye and hand protection during drilling. Match drill speed and feed pressure to the material to extend tool life. Replace the bit when signs of dulling or chipping appear to maintain hole quality and reduce risk of breakage.
