Built from hardened tool steel, this bull nose point dead center features a 3MT Morse taper shank for secure, repeatable seating in compatible spindles. The bull nose point style provides a broad contact surface suited for supporting hollow workpieces or tubing ends. With a head diameter of 2.75 inches, a point length of 1.939 inches, and a rated accuracy of 0.0001 inches, this center is well-suited for precision turning operations where runout control is critical. Machinists and toolroom technicians working on lathes and cylindrical grinders are the primary installers.\u003c\/p\u003e\u003cp\u003eThis dead center is appropriate for use in metalworking environments including job shops, production machining, and tool rooms. The 3MT Morse taper shank seats directly into a matching 3MT tailstock quill or headstock spindle without additional adapters. The bull nose configuration makes it particularly useful when the workpiece has a center bore or hollow end that a standard 60-degree point cannot properly engage. The solid (non-rotating) design means the center does not spin with the workpiece, so it is typically used in lower-speed applications or where the workpiece itself provides adequate lubrication at the contact point.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBull nose point style for supporting hollow or bored workpieces\u003c\/li\u003e\n\u003cli\u003eHardened tool steel construction for wear resistance and long service life\u003c\/li\u003e\n\u003cli\u003e3MT Morse taper shank for direct mounting in compatible tailstock quills\u003c\/li\u003e\n\u003cli\u003eAccuracy rated to 0.0001 inches for precision turning applications\u003c\/li\u003e\n\u003cli\u003eSolid (non-rotating) center design  -  no bearings to maintain or replace\u003c\/li\u003e\n\u003cli\u003e2.75 inch head diameter with 1.939 inch point length for robust workpiece support\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to fit any lathe or cylindrical grinder tailstock or headstock spindle accepting a Number 3 Morse taper (3MT).

Before seating the center, power down the lathe and ensure the spindle is fully stopped. Clean the Morse taper bore and the shank with a lint-free cloth to remove chips, oil, and debris  -  any contamination can cause improper seating and runout error. Insert the taper with a firm, straight push to engage the self-holding taper; do not use a hammer directly on the center body. Because this is a solid dead center, apply a suitable center lubricant or anti-galling compound at the workpiece contact point when running at elevated speeds to prevent heat buildup and scoring.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Type\u003c\/strong\u003e: Solid Dead Center\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Style\u003c\/strong\u003e: Bull Nose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hardened Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Morse Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Taper Size\u003c\/strong\u003e: 3MT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Diameter\u003c\/strong\u003e: 1.939 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Length\u003c\/strong\u003e: 1.939 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 2.453 inches (2-29\/64)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.953 inches (2-61\/64)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarbide-Tipped\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RITEN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RITEN","offers":[{"title":"Default Title","offer_id":67912048804146,"sku":"66503","price":775.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2e4e9e9e5fdc80a8669592df26906b0.jpg?v=1791226058","url":"https:\/\/voomisupply.com\/products\/riten-66503-solid-dead-center-bull-nose-2-3-4-in-3mt","provider":"Voomi Supply","version":"1.0","type":"link"}
