Buying Guide

Match bit diameter to the task

Choose smaller diameters for pilot holes and planting bulbs and larger diameters for timber work; available sizes here range from 3/4" to 1-1/2" and longer shafts for deeper holes

Pick the right length

Longer 17–32 inch options are useful for deep holes and reaching through thick materials, while shorter bits are better for surface work and control

Look for robust tip and screw point

A good auger has a sharp screw point or threaded tip to pull the bit into wood and maintain steady drilling with less effort

Consider shaft compatibility

Check shank type—hex or round—to ensure compatibility with your driver or drill chuck and to reduce slippage under high torque

Assess build and coating

Heat-treated steel and wear-resistant coatings improve longevity when drilling hardwood or nail-embedded lumber, common in woodworking bits from established brands
