Manufactured from high speed steel, this set delivers the hardness and wear resistance needed for counterboring operations in steel, cast iron, aluminum, and similar materials. The straight shank design provides secure chuck retention, and the 3-flute geometry promotes chip evacuation and accurate seat geometry. The set includes 4 pieces, covering the range of sizes needed for socket head cap screw clearance and seating applications in machining and fabrication work. Machinists, tool and die technicians, and maintenance professionals are the primary users of this tooling.\u003c\/p\u003e\n\u003cp\u003eThis counterbore set is suited for bench drill press, mill, or hand-held drilling applications where a flat-bottomed recess is required to seat socket head cap screws flush or below the workpiece surface. It is commonly used in general metalworking, fixture building, machine repair, and production machining environments. The solid pilot design ensures the counterbore stays centered on the existing pilot hole, reducing chatter and improving concentricity of the finished seat.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction for hardness and extended tool life in metalworking applications\u003c\/li\u003e\n  \u003cli\u003eSolid pilot design maintains concentricity with the existing drilled hole\u003c\/li\u003e\n  \u003cli\u003e3-flute configuration promotes efficient chip evacuation and clean flat-bottom seating\u003c\/li\u003e\n  \u003cli\u003eStraight shank for compatibility with standard drill chucks and milling machine collets\u003c\/li\u003e\n  \u003cli\u003e4-piece set covers 10 to 6 wire socket head cap screw sizing range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 10 to 6 wire socket head cap screws.

Secure the straight shank firmly in the chuck or collet before operation and confirm the pilot fits the existing hole without slop before beginning the counterbore cut. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Power down and de-energize the machine spindle before changing or inspecting tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: Straight Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePieces in Set\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Fastener Range\u003c\/strong\u003e: 10 to 6 Wire Socket Head Cap Screws\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.21 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GH8862005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694820884786,"sku":"GH8862005","price":131.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5ec53832bfd9304bc08c50a9205b714.jpg?v=1788328717","url":"https:\/\/voomisupply.com\/products\/value-collection-gh8862005-counterbore-set-hss-4-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
