Accupro CY01310000MSC Drill Chuck 1/2-20 Threaded Keyed

Product Description

The ACCUPRO CY01310000MSC is a keyed drill chuck designed for threaded-mount installation on drilling equipment used in machining, metalworking, and general fabrication applications. It accepts drill bits and tooling from 3/64 inch (0.0591 inch decimal) up to 1/2 inch (0.500 inch decimal), covering the range most commonly needed in production and maintenance drilling. The chuck body is constructed from steel and uses a plain bearing design. It mounts via a 1/2-20 threaded interface and is tightened and released using a K2 chuck key. Machinists, tool-room technicians, and maintenance mechanics are the primary users of this chuck type.

This chuck is suited for benchtop drill presses, floor-standing drill presses, and compatible portable drilling equipment that accept a 1/2-20 threaded spindle mount. It is appropriate for light to moderate-duty drilling in metal, wood, plastic, and composite materials in both shop and field maintenance environments. The keyed design provides positive clamping force, making it well suited for applications where secure bit retention under load is a priority.

Key Features

• Capacity range of 3/64 inch to 1/2 inch accommodates a wide variety of drill bit shanks

• Plain bearing construction for straightforward service and maintenance

Compatibility

Designed as a replacement or spare keyed drill chuck for drill presses and drilling equipment fitted with a 1/2-20 threaded spindle mount.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with drill press spindle components. Power down and lock out the drill press before removing or installing any chuck. Thread the chuck onto the spindle by hand first to confirm proper thread engagement, then tighten to the spindle manufacturer's specification using appropriate tooling. Inspect the chuck key and key socket for wear before returning the equipment to service.
