Buying Guide

Match bit diameter to your task

Choose larger diameters (1-1/2 in and up) for big holes or posts and smaller diameters (3/4 in to 1-1/4 in) for pilot holes and planting bulbs

Check shaft type and compatibility

Confirm hex or solid shaft compatibility with your drill or driver to avoid slipping and to use available extensions

Prioritize length for reach

Longer bits (17 in to 36 in) provide deeper reach for ship, post, or bulb planting while shorter ones are easier to control in handheld drills

Look for construction and coating

Carbide or carbon steel and welded or tempered flighting resist wear and cut through wood or nail-embedded material more reliably

Consider included accessories

Sets with extensions or multiple diameters increase versatility for planting and ground work without buying extra bits
