Accupro CY01308000MSC Drill Chuck 1/2 Inch JT6 Keyed

Product Description

The ACCUPRO CY01308000MSC is a keyed drill chuck designed for tapered-mount spindles using a JT6 taper. It accepts drill bits and round-shank tooling from 3/64 inch (0.0591 inch) up to 1/2 inch (0.5000 inch) in diameter, covering the range used in most general-purpose drilling applications on drill presses, lathes, and milling machines. The chuck body is constructed of steel and uses a plain bearing design. The 46 mm sleeve diameter and K2 key provide a secure grip on the tool shank. Machinists, tool-room technicians, and maintenance mechanics are the primary installers of this type of chuck.

This chuck is suited for use on drill presses, bench lathes, and similar machine-tool spindles equipped with a JT6 Jacobs taper mount. It handles both light-duty production drilling and general maintenance drilling tasks in residential shop, commercial, and industrial settings. The keyed design ensures reliable clamping force when drilling ferrous and non-ferrous materials. It is a direct replacement or upgrade option for worn or damaged JT6-mount chucks of equivalent capacity.

Key Features

• Capacity range from 3/64 inch to 1/2 inch accommodates a wide variety of drill bit shank sizes
• JT6 tapered mount for positive, repeatable seating on compatible spindles
• Keyed operation with K2 key for maximum clamping force and reduced slippage
• Steel chuck body for durability in production and maintenance environments
• 46 mm sleeve diameter provides a substantial grip surface for tightening
• Plain bearing design suits general-purpose drilling at standard spindle speeds

Installation Notes

Installation and removal of this chuck should be performed by a qualified machinist or maintenance technician familiar with tapered-mount tooling. Power down and lock out the machine at the main disconnect before mounting or removing the chuck. Use a chuck removal wedge or drift and a soft mallet to seat or break the taper - never use excessive force that could damage the spindle bore. Confirm taper fit and runout with a dial indicator after mounting before returning the machine to service.
