Buying Guide

Match bit type to material

Use carbide-tipped, cross-type bits for concrete and masonry and choose standard bits for softer materials to prevent chipping

Choose correct length and shank

Select a length that reaches your work without overstressing the drill and confirm the shank fits your chuck or mandrel

Check compatibility with hammer drills

For masonry or concrete, pick bits labeled for hammer or SDS-style impact use to ensure effective drilling and longer life

Assess carbide head quality

Look for cross-type or forged carbide heads for cleaner entry and better heat resistance during long holes

Consider value over flashy features

Prioritize durable cutting geometry and appropriate length rather than added coatings or packaging when staying under $50
