Hardened and ground Drill Chuck Arbors, used to mount a drill chuck or any other tool which has a female taper onto a machine such as a drilling machine which has a female taper socket in its workhead.
Manufactured from case hardened Hi-Tensile Steel (20 MnCr5/SAE 8620), all arbors are case hardened 54 - 58 HRC for increased resistance to wear.
Precision grinding to very close tolerance with concentricity controlled to within 0.0004" (10 microns) and accurately gauged self locking tapers ensure close tolerance fit.
