Drill bit Makita B-29094 10 mm diameter, 2 cutting edges

Straight drill bit Makita B-29094 with a 10 mm diameter and two cutting edges is a general-purpose twist bit designed for standard drilling tasks. It fits drills and drivers that accept 10 mm shanks and is intended to deliver stable, controlled drilling performance in common workshop and on-site applications. The geometry with two cutting edges promotes efficient chip removal and reduces wobble during entry and through-holes in compatible materials.

Advantages

This 10 mm drill bit features a balanced two-flute design that provides steady drilling with reduced walking and reliable centring. The straight shank and standard diameter make it easy to secure in chucks and quick-change adaptors. The bit’s cutting geometry supports effective material removal and consistent hole quality across a range of materials such as wood, soft metals and plastics when used with appropriate speed and feed.

Suitable for

• Drilling holes in soft and medium-density wood
• Drilling through plastics and composite panels
• Light drilling in soft metals such as aluminium and thin sheet metal
• Workshop tasks and on-site installations requiring a standard 10 mm hole

Key specifications

• Diameter: 10 mm
• Cutting edges: 2 (two-flute twist geometry)
• Shank type: straight, compatible with standard 10 mm chucks
• Typical applications: wood, soft metals, plastics
• Design: general-purpose twist drill for stable drilling and chip evacuation

How to use

Place the drill bit securely in the drill chuck and tighten according to the drill manufacturer’s instructions. Select an appropriate rotational speed and apply steady, even pressure; lower speeds are recommended for metals and higher speeds for wood and plastics, while avoiding excessive feed that can cause bit breakage or poor hole quality. Use cutting fluid or lubricant when drilling metals to extend bit life and clear chips frequently when drilling deeper holes. Keep the drill perpendicular to the work surface for accurate, round holes.

Usage recommendations

For best results, match drill speed and feed to the material being drilled: lower RPM with light cutting fluid for metals, moderate RPM for plastics, and higher RPM with firm support for wood. Inspect the bit for wear or bluntness before use and replace if cutting performance declines. Use appropriate personal protective equipment such as safety glasses and hearing protection during drilling operations.
