Buying Guide

Choose the right shank size

1/4" and 1/2" shanks offer different rigidity—1/2" reduces vibration for larger cutters, while 1/4" fits compact routers and many CNC collets

Prefer carbide or tungsten tips for longevity

Carbide inserts and tungsten-carbide constructions maintain sharpness longer than high-speed steel, improving edge quality on hardwoods and laminates

Match cutter geometry to the operation

Use dedicated grooving bits for slotting, corner-round bits for rounded profiles, and spoilboard surfacing cutters for flattening CNC spoilboards

Consider sets vs single bits

25-piece sets give broader versatility for edge treatment and grooving, while single specialty cutters (e.g., spoilboard or corner-round) can offer better value for a specific task

Check user ratings and build details

Prioritize bits with consistent user scores and clear material specs (carbide-tipped, carbide inserts, tungsten-carbide) to gauge real-world durability and finish
