This is a new Accupro High Performance Toolholding keyless drill chuck with an integrated Morse Taper #4 (4MT) shank, eliminating the need for a separate arbor and reducing stack-up error. The chuck accepts drill shanks from 1/32 in to 1/2 in capacity and is certified to a T.I.R. (runout) of 0.0016 in or less per the included Accupro Certificate of Inspection. The dual-ring keyless mechanism allows tool changes by hand — the lower knurled ring locks the chuck while the upper ring opens/closes the jaws — and a spanner wrench (included, stamped ANR120000) provides additional torque for secure clamping. Made in Spain, this unit is suited for drill press and milling machine applications where a 4MT spindle taper is present. MSC part number 63673446, Lot 400761.
