    The most widely used type of collet, these collets hold cutting tools in ER collet chucks for milling, drilling, and routing. Spring slots clamp evenly around the shank to minimize runout for clean, accurate cuts and long tool life. The slots flex to grip slightly undersized shanks too, so you don't need an exact match for each cutting tool in your lineup. You can also use these collets in ER collet fixtures and custom setups to keep small round parts centered.
    52100 Alloy Steel—Hardened 52100 alloy steel collets are made from the same tough material used to make bearings. They’re more wear-resistant than basic spring steel collets but will wear faster than hardened chrome-moly steel collets if you change bits frequently.
