Accupro CBS2517000MSC Drill Chuck 1 Inch JT5 Tapered Mount

Product Description

The ACCUPRO CBS2517000MSC is a keyed drill chuck designed for heavy-duty drilling applications on drill presses, lathes, and similar machine tools. It accepts bit shanks from 13/64 inch (0.1968 inch) up to 1 inch (1.0000 inch), covering a wide range of drill bit sizes used in production and maintenance environments. The chuck mounts via a JT5 Jacobs taper and uses a K5 key for tightening and releasing. Internal ball bearing construction supports smooth rotation and consistent grip under load. The steel body is built to withstand repeated use in demanding shop conditions. Licensed HVAC techs, machinists, and tool-and-die tradespeople will recognize this as a standard industrial-grade chuck configuration.

This chuck suits drill press setups and other rotating machine tool spindles that accept a JT5 tapered arbor. It is appropriate for both production shop environments and maintenance/repair operations where a reliable, full-range keyed chuck is needed. The 93 mm sleeve diameter and ball bearing internals make it a practical choice for medium-to-large capacity drilling tasks in metal, wood, or composite materials. A closed length of approximately 5.79 inches and an open length of approximately 4.41 inches should be confirmed against machine clearances before installation.

Compatibility

Designed to fit machine tool spindles with a JT5 Jacobs taper mount. Verify spindle taper size and machine clearances against the closed length of 5.79 inches and open length of 4.41 inches before installation.

Installation Notes

Installation is typically performed by a machinist or qualified tool technician. Power down and lock out the machine before mounting or removing the chuck. The JT5 taper should be cleaned and inspected for damage or debris before seating to ensure proper alignment and secure fit. Do not use a hammer directly on the chuck body; use an appropriate arbor press or draw bar method as required by the machine manufacturer.
