Buying Guide

Match shaft and chuck size

Confirm your drill accepts the bit's shaft (hex, solid round, or 3/4") to avoid adapters and ensure secure fit

Choose length for the job

Select shorter 17–18" bits for standard woodworking and longer 32–36" or extension-compatible bits for planting or deep holes

Material and tip design matter

Look for carbide or heat-treated steel and cutting-tip designs for clean boring in wood, nail-embedded boards, or compacted soil

Consider included extensions or sets

Sets and extension-ready bits add versatility for bulb planting or varied hole diameters without buying extra tools

Intended use: wood vs. earth vs. planting

Wood augers and ship augers suit timber; earth and garden augers have wider diameters and reinforced shafts for soil and post work
