High Precision
Internal Cooling ER Collet
ER32 Internal Cooling Collet (3-20mm), 18PCS/SET
ER40 Internal Cooling Collet (3-26mm), 24PCS/SET
Professional Terminology Explanation
- High Precision: High concentricity and ultra-low
runout, suitable for high-precision CNC machining.
- Internal cooling ER collet: Through-coolant ER
collet with central water outlet design, delivering coolant directly to the
cutting area for effective cooling and lubrication.
- ER32 3-20mm 18PCS / ER40 3-26mm 24PCS: Standard
ER series collet models, fully compatible with matching CNC tool holders with
wide versatility. Clamping diameter range, covering common tool sizes for
finishing and roughing processing. Complete set with full size coverage to meet
diverse machining requirements.
Specification
High-precision internal cooling ER collets feature
central through-coolant structure for direct tool cooling, reducing cutting
heat and improving machining efficiency and surface finish. Available in two
sets: ER32 (3-20mm, 18PCS) and ER40 (3-26mm, 24PCS). Low runout, firm clamping,
ideal for high-precision CNC cutting, drilling and milling processing.
