High quality Collet Chuck ER16M 3/4" With Straight Shank 3.42"

C ER/M straight tool holders for mechanical spindle and cutting tool and other accessory tool connection. Is a simple, popular spindle shank connection standard, mainly C8, C10, C12, C16... Etc.. Mold industry, and high-speed engraving machine, used more. ER/M straight shank is longer, suitable for deep hole processing. Comprehensive inspection way of chuck: Surface of the clamping inner hole is grinding by high speed inner-aperture grinder, and inspect by standard pneumatic measurement instrument, the big end area rate is above 90%. TYPE A / TYPE M / TYPE UM ARE DIFFENT, WHICH CAN BE JUDGED BY THEIR APPEARANCE ◎ Shank is longer, suitable for deep hole processing. ◎ Outer diameter and other parts after grinding, eliminate the unbalanced allowance, conducive to the stability of the cutting. ◎ Can reduce to the selection of lengthen cutting tool, reduce cost and improve efficiency. 1.
