Wood auger bit set Hikoki HK-781995, 6 pieces, sizes 10–20 mm

Hikoki HK-781995 wood auger bit set contains six auger bits sized 10 mm, 12 mm, 14 mm, 16 mm, 18 mm and 20 mm designed for creating clean, deep holes in timber and structural lumber. The bits feature traditional auger geometry with a lead screw point and spiral flute that guide the bit into the wood and evacuate chips efficiently. The set is intended for use with manual braces and power drills that accept compatible shank sizes, providing stable drilling for woodworking, carpentry, joinery and construction site tasks.

Advantages

The auger profile and lead screw deliver accurate centring and steady penetration, reducing the need for pilot holes and improving hole straightness in soft and hardwoods. Deep spiral flutes enable continuous chip removal, minimising clogging and reducing heat build-up during extended drilling. Hardened cutting edges maintain sharpness over repeated use, while the range of diameters from 10 mm to 20 mm covers common hole sizes required for dowels, through-holes and cable or pipe passages in timber work.

Key specifications

How to use

Select the auger bit with the required diameter for the task and secure it in a compatible chuck or brace. Position the lead screw point on the marked drilling location and apply steady axial pressure while maintaining alignment. For power drilling, start at low speed to engage the lead screw and then increase speed as the bit advances; for manual braces maintain a consistent turning motion. Periodically withdraw the bit to clear chips from the flutes when drilling deep holes, and allow the bit to cool during prolonged use.

Recommendations

Use appropriate personal protective equipment (safety glasses and gloves) and clamp workpieces to prevent movement. Match bit diameter to dowel or cable size with a small allowance for fit. Avoid excessive side loading to reduce wear and risk of bit breakage. For prolonged sharpness, finish cuts with light feed and consider occasional sharpening of cutting edges according to wood type.
