ER Collets
Available969 products
ER collets are specialized sleeve bushings that hold round-shank cutting tools (such as endmills, taps, drill bits) in a milling machine or CNC spindle. Collets install in a compatible collet chuck and center the cutting tool in the spindle to enhance cutting accuracy and concentricity.
Standard ER Collets
Standard ER collets compress to clamp cutting tools over a set size range to allow the bit to be changed without changing out the collet.
