Accupro NP01350400MSC Drill Chuck CAT50 Keyless 1/2 Inch

Product Description

The ACCUPRO NP01350400MSC is a keyless drill chuck designed for CAT50 tooling systems used in CNC machining centers and heavy-duty drilling applications. It accepts drill shanks from 1/32 inch (0.0393 inch) up to 1/2 inch (0.5000 inch), making it suitable for a wide range of cutting tool diameters. The chuck uses an integral shank mount with a taper shank configuration and features a ball bearing design for smooth, consistent operation. Total indicator runout (TIR) is rated at 0.0016 inch, supporting accurate hole placement and extended tool life. The 48 mm sleeve diameter and steel construction are built to handle the torque demands of production machining environments. A spanner wrench is included.

This chuck is intended for use in vertical and horizontal machining centers equipped with CAT50 spindle interfaces. It fits production and job-shop settings where quick tool changes and repeatable clamping are required. The keyless design eliminates the need for a separate chuck key during tool changes, reducing changeover time on the floor. Closed length is 107 mm and open length is 96 mm, which should be accounted for when calculating tool clearance and Z-axis offsets during setup.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before mounting or removing the chuck. Ensure the CAT50 taper and spindle bore are clean and free of chips or burrs before seating the chuck. Verify tool runout with a dial indicator after installation and before initiating any cutting cycle.
