Buying Guide

Choose the right substrate

Carbide and M42 cobalt each suit different jobs: carbide for high-speed, hard materials and cobalt for tougher roughing and heat resistance

Match flute count to material

Two flutes clear chips better in soft alloys and steels while 3–4 flutes give better surface finish and rigidity for harder materials

Pick diameter and length for the job

Select a diameter that fits toolpaths and a fluted length short enough to minimize deflection but long enough for required depth

Consider coatings and edge treatment

TiAlN or similar coatings extend life in high-temperature cutting and roughing, while micrograin carbide offers toughness for precise finishing

Look for application-specific geometry

U-type or roughing geometries are better for aluminum or heavy stock removal, whereas square-nose profiles are ideal for flat-bottom pockets

Assess value vs. quantity

Multi-packs can lower cost per cutter for repeat jobs, while single precision cutters may be better for finish work
