It accepts bit shanks from 1\/32 inch (0.0394 inches decimal) up to 3\/8 inch (0.375 inches decimal), covering the most common twist drill and accessory sizes used in metalworking, woodworking, and general fabrication. The chuck mounts via a 3\/8-24 threaded arbor interface, uses a K34 key for tightening and releasing, and features a plain bearing design with a steel chuck body. The sleeve diameter measures 37 millimeters (1.457 inches) and closed length is approximately 60 millimeters (2.36 inches). It is typically installed by machinists, maintenance technicians, and tradespeople working with drill presses, lathes, or portable drilling equipment.\u003c\/p\u003e\u003cp\u003eThis chuck is suited for light-duty to medium-duty drilling on drill press spindles, lathe tailstocks, and similar threaded-arbor toolholding setups. The 3\/8-24 threaded mount is a common standard found on benchtop drill presses and portable drilling attachments used in HVAC, electrical, plumbing, and general maintenance trades. Its compact sleeve profile and keyed design provide reliable gripping force and repeatable bit seating across a range of drill diameters within its capacity range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCapacity range: 1\/32 inch to 3\/8 inch (0.0394 to 0.375 inches decimal)\u003c\/li\u003e\n\u003cli\u003eThreaded mount with 3\/8-24 inch thread size for direct spindle attachment\u003c\/li\u003e\n\u003cli\u003eKeyed operation using K34 key for positive bit clamping and release\u003c\/li\u003e\n\u003cli\u003eSteel chuck body for durability in production and maintenance drilling\u003c\/li\u003e\n\u003cli\u003ePlain bearing design — straightforward construction, easy to service\u003c\/li\u003e\n\u003cli\u003e37 mm (1.457 inch) sleeve diameter fits standard chuck guard clearances on common drill press models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or spare keyed drill chuck for drill presses, lathe tailstocks, and other toolholding equipment with a standard 3\/8-24 threaded spindle mount.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or qualified maintenance technician.
