Accupro CKS1607020MSC Keyless Drill Chuck JT33 5/8 Inch

Product Description

The ACCUPRO CKS1607020MSC is a keyless drill chuck designed for tapered-mount spindles using a JT33 arbor interface. It accepts drill bits and tooling from 1/8 inch up to 5/8 inch in diameter, covering a broad range of hole-making and boring applications. The chuck body is constructed from steel and runs on a ball bearing mechanism that supports smooth, repeatable tool changes without a key. With a sleeve diameter of approximately 2.05 inches (52 mm) and a closed length of approximately 4.13 inches (105 mm), it is sized for benchtop drill presses, light machine tools, and portable power equipment. Machinists, toolroom technicians, and maintenance trades install this chuck as a direct replacement or upgrade on compatible JT33 spindles.

This chuck suits residential shop equipment and light industrial machine tools where a JT33 tapered mount is standard. Typical installations include benchtop and floor-model drill presses, milling machine quill attachments, and similar rotating-spindle equipment. The keyless design allows rapid bit changes in production or service environments where downtime must be kept short. Its steel construction handles the repetitive clamping forces common in drilling steel, aluminum, wood, and plastics.

• Steel chuck body provides durability under repeated use
• Sleeve diameter of approximately 2.05 inches (52 mm) fits standard chuck guard clearances

Compatibility

Designed for use with machine tool spindles fitted with a JT33 Jacobs taper mount. Verify spindle taper type before installation.

Installation Notes

Installation should be performed by a qualified machinist or tool technician familiar with tapered-mount chuck fitting procedures. Power off and lock out the machine at the disconnect before removing or seating the chuck. Seat the JT33 taper by driving the chuck onto the spindle with a sharp mallet strike through a wood block to protect the sleeve — never strike the sleeve directly. Inspect the taper surfaces for burrs or contamination before assembly, as debris on the mating taper will cause runout.
