ER-16 Collets

Accu-Collets ER COLLETS
AccuCollets™ Precision and UltraPrecision Collets DIN 6499-form B (ER) set new standards of accuracy.
Precision Collets concentricity is 15 microns or 0.0005" TIR or better
Ultra Precision Collets is 6 microns or 0.0002" TIR or better

• Concentricity is 13 microns or 0.0005" TIR or better
• Manufactured with Swiss technology
• Crafted from high quality European alloy spring steel
• TRUE INCH and metric sizes
• Fractional Collets manufactured specifically for US market requirements. Use "on size" collets for best results
• 16 slot construction for rigid clamping and extra concentricity
• Accu-Collets improve tool life, part finish and reduces spindle wear
• Can be used for drilling, milling, tapping and reaming

Precision ER Collets 0.0005" TIR or better as measured over the entire clamping range per DIN 6499 Standards
