Built from high speed steel, it delivers the hardness and wear resistance required for consistent cutting in ferrous and non-ferrous materials. The tool features a 1\/2 inch counterbore diameter, an 11\/32 inch pilot diameter sized for 5\/16 inch fasteners, and a 3-flute cutting geometry that promotes chip clearance and smooth bore finish. The No. 2 Morse Taper shank mounts directly into compatible machine spindles for secure, concentric tool holding. This counterbore is intended for forward cutting direction and is classified as standard pilot style, not aircraft style.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is suited for job shop, production machining, and maintenance environments where accurate counterboring of bolt or screw clearance holes is required. It is used in drill presses, milling machines, and similar machine tools equipped with a No. 2 Morse Taper spindle. Typical applications include creating flush or recessed seating surfaces for socket head cap screws, hex bolts, and similar 5\/16 inch fasteners in steel, aluminum, and cast iron workpieces. Machinists, toolroom technicians, and maintenance mechanics are the primary users of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch counterbore diameter sized for standard 5\/16 inch fastener head seating\u003c\/li\u003e\n  \u003cli\u003e11\/32 inch integral pilot diameter provides accurate bore alignment during cutting\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for hardness and wear resistance in metal cutting\u003c\/li\u003e\n  \u003cli\u003e3-flute design promotes chip evacuation and reduces cutting pressure\u003c\/li\u003e\n  \u003cli\u003eNo. 2 Morse Taper (2MT) shank for direct mounting in compatible spindles\u003c\/li\u003e\n  \u003cli\u003eForward cutting direction, standard pilot style, non-aircraft configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in machine tool spindles accepting a No. 2 Morse Taper shank.

Ensure the machine is fully powered down and the spindle is at rest before seating or removing the taper shank. Clean the taper bore and shank contact surfaces before mounting to ensure proper seating and concentricity. Always operate at speeds appropriate for the workpiece material and tool diameter per standard machining practice.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 11\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Size Compatibility\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed 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 Designation\u003c\/strong\u003e: 2MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Forward\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard or Oversize Pilot\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAircraft Style\u003c\/strong\u003e: No\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GH8861205\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693395607858,"sku":"GH8861205","price":112.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb5c7244849f83ee4eb1efebe90dcef1.jpg?v=1788311729","url":"https:\/\/voomisupply.com\/products\/value-collection-gh8861205-solid-pilot-counterbore-hss-2mt","provider":"Voomi Supply","version":"1.0","type":"link"}
