Buying Guide

Cutting edge and rim style

Serrated or carbide cutting edges (noted in some sets) slice cleaner and reduce tear-out on hardwoods compared with plain carbon rims

Shank type and fit

Choose straight or hex shanks based on your drill chuck: hex shanks like INTOO’s sets improve grip for cordless drills, while 3/8 in straight shanks suit standard chucks and drill presses

Individual bits vs. sets

Single larger diameter bits (for example 7/8 in sizes) are useful when you only need occasional large holes, whereas 8–16 piece sets cover a wider range of hole sizes for general woodworking

Material and build

Carbon steel sets are economical for softwoods and general use; carbide or hardened designs hold an edge longer for repeated cuts in hardwood and plywood

Compatibility with your tool and project

Match bit diameters and shank sizes to your drill or drill press capacity and pick a set that includes the most frequently used sizes for cabinetmaking, hinge boring, or hardware installation
