With a body diameter of 54 mm (approximately 2.126 inches) and a Graflex 5 integral mount with a modular connection shank, this head accepts twin-cutter tooling for balanced cutting and improved surface finish. It covers a bore diameter range of 64 mm to 86 mm (approximately 2.52 inches to 3.39 inches), making it well suited for medium-bore applications. Actuation is manual, giving the operator direct control over diameter adjustment without powered tooling. The head belongs to the EPB series and weighs 1 pound.\u003c\/p\u003e\u003cp\u003eThis boring head is intended for use in metalworking environments where accurate bore sizing is required. The Graflex 5 modular connection shank integrates directly with compatible EPB-series tooling systems, allowing the unit to be mounted without an intermediate adaptor. Typical applications include finish boring of bearing housings, flanges, and precision bores in ferrous and non-ferrous workpiece materials. It is used by machinist tradespeople and toolroom technicians operating vertical or horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwin-cutter design provides balanced cutting forces for improved bore geometry\u003c\/li\u003e\n\u003cli\u003eManual actuation allows precise diameter adjustment at the machine\u003c\/li\u003e\n\u003cli\u003eBore diameter range: 64 mm to 86 mm (approximately 2.52 inches to 3.39 inches)\u003c\/li\u003e\n\u003cli\u003eGraflex 5 integral mount with modular connection shank for direct EPB-system interface\u003c\/li\u003e\n\u003cli\u003e82 mm (approximately 3.23 inches) projection for reach in standard boring setups\u003c\/li\u003e\n\u003cli\u003eCompact 54 mm body diameter minimizes interference in tight bore entry conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with EPB-series modular tooling systems using a Graflex 5 modular connection interface.

The spindle must be fully stopped and the machine placed in a safe, locked-out state before mounting or adjusting the boring head. Diameter adjustments should be made with the appropriate adjustment tool per the tooling system manufacturer's procedure, and the locking mechanism must be secured before initiating a cut. Refer to applicable shop safety standards and machine tool operating procedures during setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Twin Cutter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuation Type\u003c\/strong\u003e: Manual\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 54 mm (approximately 2.13 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 64 mm (approximately 2.52 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 86 mm (approximately 3.39 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 82 mm (approximately 3.23 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Integral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Modular Connection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModular Connection Size\u003c\/strong\u003e: Graflex 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EPB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00026692\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560216068402,"sku":"00026692","price":1903.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5e35b1274de5ee9f022100f5d2521e8_199b82da-23f6-4db3-b9a3-2f1c572d3bbc.jpg?v=1786449442","url":"https:\/\/voomisupply.com\/products\/seco-00026692-boring-head-54mm-twin-cutter-graflex-5-epb","provider":"Voomi Supply","version":"1.0","type":"link"}
