It accepts number 7 and number 17 center drills and features a 5\/8 inch center drill body diameter with a 1\/4 inch projection. The MT3 taper provides a secure, self-holding connection to the machine spindle or tailstock, reducing runout and maintaining concentricity during spotting and center drilling operations. This driver is a standard tooling component used by machinists and tool-and-die trades on manual and CNC lathes.\u003c\/p\u003e\n\u003cp\u003eThis center drill driver is suited for metalworking environments where precise center drilling is required prior to turning between centers or drilling operations. It is commonly installed in lathe tailstocks or milling machine spindles equipped with an MT3 taper socket. The 5\/8 inch body diameter and 1\/4 inch projection make it compatible with standard number 7 and number 17 combined drill and countersink tooling used in production and job-shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT3 outside Morse taper shank for secure self-holding fit in standard MT3 sockets\u003c\/li\u003e\n  \u003cli\u003eAccepts number 7 and number 17 center drills\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch center drill body diameter for positive drill retention\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch projection keeps the center drill close to the holder for rigidity\u003c\/li\u003e\n  \u003cli\u003eDrill tang not compatible  -  designed for straight-shank center drill retention\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.44 pounds for easy handling and quick tooling changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style tooling driver for lathes and machining centers equipped with an MT3 Morse taper spindle or tailstock socket, compatible with number 7 and number 17 center drills with a 5\/8 inch body diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tool-and-die technicians. Power down and de-energize the machine spindle before seating or removing the driver from the taper socket. Clean the MT3 taper bore and driver shank thoroughly before insertion to ensure full taper contact and prevent fretting. Never use the driver if the taper surfaces show damage, as improper seating can cause runout or unexpected ejection during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Type\u003c\/strong\u003e: MT3 Outside Morse Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Center Drill Sizes\u003c\/strong\u003e: Number 7 and Number 17\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Drill Body Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Tang Compatible\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: COLLIS TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73501\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COLLIS TOOL","offers":[{"title":"Default Title","offer_id":67906086502706,"sku":"73501","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6710c92e5a04dfb1287658dba302adf.jpg?v=1791164761","url":"https:\/\/voomisupply.com\/products\/collis-tool-73501-center-drill-driver-mt3-morse-taper","provider":"Voomi Supply","version":"1.0","type":"link"}
