Accupro HX01650210MSC Drill Chuck BT50 1/8-5/8 in Keyed

Product Description

The ACCUPRO HX01650210MSC is a keyed drill chuck designed for CNC machining centers and milling applications requiring a BT50 integral shank mount. It accepts drill and tool shank diameters from 0.125 inches to 0.625 inches, making it suitable for a wide range of drilling, reaming, and boring operations. The chuck body is constructed from steel and uses a plain bearing design with a 57 mm sleeve diameter. A hex 1/4 key operates the keyed jaw system. Maximum spindle speed is 8,000 RPM, and total indicator runout (TIR) is rated at 0.0012 inches, supporting precise hole location in production environments.

This drill chuck is used in CNC milling machines and machining centers equipped with BT50 spindle tooling systems. The integral shank mount eliminates the need for a separate arbor, reducing assembly stack-up and potential runout. It is well-suited for production-floor and job-shop environments where operators need a reliable, high-capacity chuck for ferrous and non-ferrous workpiece materials. The coolant style designation B+AD indicates compatibility with through-coolant and air-direct delivery configurations, supporting chip evacuation during deep-hole drilling operations.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the chuck. Clean the spindle taper and chuck shank thoroughly before seating to prevent runout errors caused by contamination. Follow the machine tool manufacturer's draw bar torque and retention stud specifications when securing the toolholder.
