Built from cobalt steel with a bright, uncoated finish, this tool delivers solid performance in harder materials where high-speed steel would wear prematurely. The straight shank measures 1\/2 inch in diameter and 3-1\/16 inches in length, with an overall length of 4-5\/16 inches. The counterbore diameter is 17\/32 inches, and the interchangeable pilot accepts a 3\/16-inch pilot shank diameter. Right-hand cutting direction is standard. Machinists and tool-and-die professionals reach for cobalt-construction counterbores when working stainless, alloy steels, and other abrasion-resistant materials.\u003c\/p\u003e\u003cp\u003eThis counterbore is suited for use in manual mills, drill presses, and CNC machining centers where a standard counterbore seat is required ahead of a fastener head. The interchangeable pilot design allows the pilot to be swapped out independently of the body, reducing tooling cost when only the pilot wears. Typical applications include aerospace-adjacent fabrication, structural steel work, and general machine shop use where socket head cap screw clearance bores or stepped hole features are needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt steel construction for improved wear resistance in hard and abrasion-resistant workpiece materials\u003c\/li\u003e\n\u003cli\u003e3-flute geometry provides balanced cutting action and good chip evacuation\u003c\/li\u003e\n\u003cli\u003eInterchangeable pilot accepts a 3\/16-inch pilot shank for flexible pilot replacement without replacing the full body\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish allows direct visual inspection of the cutting edges\u003c\/li\u003e\n\u003cli\u003eStraight 1\/2-inch shank for compatibility with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction matches standard spindle rotation on most machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-shank tool holders, drill chucks, and collet systems accepting a 1\/2-inch shank.

Secure the straight shank firmly in a drill chuck or collet to the full recommended engagement depth before operation. Ensure the pilot is properly seated and locked before initiating the cut. Power down the machine and confirm the spindle has stopped completely before changing pilots or inspecting cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 17\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Shank Diameter Compatibility\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright, Uncoated, Polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAircraft Style\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: GH8815342\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706421805362,"sku":"GH8815342","price":124.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8cf2c9b4525e0c95ecf704a878f85de.jpg?v=1788434290","url":"https:\/\/voomisupply.com\/products\/value-collection-gh8815342-counterbore-17-32-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
