The driver accepts taps with a 0.8-inch shank diameter and a 0.6-inch square drive. Tap entry depth is 1.63 inches, with a 2.375-inch projection from the shank face. Weighing 2.4 pounds, this driver is built for rigidity and repeatability in tapping operations on drill presses, milling machines, and lathes used in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis tapping driver is suited for machine shops, maintenance facilities, and industrial production environments where consistent, precise tapping is required. It is used in applications where an MT4-spindle machine performs threaded hole operations in metal or similar materials. The 1-inch tap capacity makes it appropriate for larger-diameter threading work typical in heavy fabrication and repair operations. Licensed machinists and tool-and-die professionals are the primary installers and operators of this tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT4 taper shank for positive, repeatable seating in MT4-compatible machine spindles\u003c\/li\u003e\n  \u003cli\u003eAccepts 1-inch taps with 0.8-inch shank diameter\u003c\/li\u003e\n  \u003cli\u003e0.6-inch tap shank square drive for positive torque transfer\u003c\/li\u003e\n  \u003cli\u003e1.63-inch tap entry depth for adequate engagement on standard tap shanks\u003c\/li\u003e\n  \u003cli\u003e2.375-inch projection provides clearance for workpiece access\u003c\/li\u003e\n  \u003cli\u003e2.4-pound solid construction supports stable, vibration-resistant tapping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1-inch taps featuring a 0.8-inch shank diameter and 0.6-inch square on machines equipped with an MT4-taper spindle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by a qualified machinist familiar with Morse taper tooling. Power down and lock out the machine before seating or removing the taper shank. Ensure the taper surfaces are clean and free of burrs before insertion to achieve full shank contact. Verify tap shank dimensions match driver specifications before use to avoid slippage or damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Entry Depth\u003c\/strong\u003e: 1.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Shank Diameter\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Shank Square\u003c\/strong\u003e: 0.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: MT4 Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.4 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: 70403\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COLLIS TOOL","offers":[{"title":"Default Title","offer_id":67906266693938,"sku":"70403","price":134.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a7ea8e666e201d2fba62f0452eaefc8.jpg?v=1791166728","url":"https:\/\/voomisupply.com\/products\/collis-tool-70403-standard-tapping-driver-mt4-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
