1、The lathe collet come with strong clamping force, high rigidity and low noise, very practical 2、Made after heat treatment and cold drawing hardening, the strength is relatively high, with a certain degree of flexibility and plasticity 3、Quenching processing with fine workmanship, bring sturdiness and durability, adopt inner hole grinding 4、65Mn material have high hardness greater than HRC48‑55°, with 0.005 high accuracy 5、Widely used in milling, drilling, tapping, engraving, CNC, half‑cone angle design of the spindle machine collet, which bring more clamping force <p class="wang-edit-text"><p class="wang-edit-text">Item Type: ColletMaterial: 65 MnAccuracy: 0.005Hardness: &gt; HRC48-55°Carburizing Depth: &gt;0.8mmSurface Roughness: &gt;0.8MMDiameter: Approx.&nbsp;1/4mmUses: Widely used in milling, drilling, tapping, engraving, CNC, half-cone angle design of the spindle machine collet bring more clamping force<style> .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }</style> 1 x Collet
