Accupro CY01005000MSC Drill Chuck 3/8 Inch JT2 Tapered Mount

Product Description

The ACCUPRO CY01005000MSC is a keyed drill chuck designed for use with tapered-mount drill press and machine tool spindles. It accepts bit shanks from 1/32 inch up to 3/8 inch (0.0394 to 0.3750 inches in decimal), making it suited for a wide range of light to medium drilling applications. The chuck body is constructed from steel for durability under repeated clamping cycles. Clamping is achieved with the included K34 key, which engages the sleeve to secure the bit firmly before operation. The sleeve diameter measures 37 millimeters (approximately 1.46 inches), and the chuck has a closed length of approximately 2.36 inches and an open length of approximately 2.01 inches.

This chuck is intended for use on drill presses, milling machines, lathes, and similar machine tools that accept a JT2 (Jacobs Taper No. 2) spindle mount. It is appropriate for shop environments where a secure, positive bit grip is required for metal, wood, or plastic drilling operations. The keyed design provides more clamping force and retention than keyless chucks, making it a common choice for stationary machine tool applications in production and maintenance shops.

Key Features

• Capacity range of 1/32 to 3/8 inches accommodates a broad selection of twist drill bit shanks
• JT2 tapered mount for positive, self-seating fit on compatible machine tool spindles
• Keyed design with K34 key delivers firm, slip-resistant bit retention
• Steel chuck body construction for long service life under repeated use
• Plain bearing type suitable for standard-speed drill press and machine tool applications
• 37 mm sleeve diameter provides a stable gripping surface for key engagement

Compatibility

Designed for machine tool spindles with a JT2 (Jacobs Taper No. 2) tapered mount. Confirm spindle taper designation before installation, as JT2 is not interchangeable with JT1, JT3, or other Jacobs taper sizes.

Installation Notes

Installation should be performed by a qualified machinist or tool-room technician familiar with tapered chuck mounting procedures. Power down and lock out the machine before seating or removing the chuck. The taper should be clean and free of oil, burrs, or debris before pressing the chuck onto the spindle to ensure proper seating and concentricity. Use an appropriate chuck removal tool or drift to unseat the chuck without damaging the spindle bore.
