It features a 90-degree included angle with a 45-degree centerline angle, a 1-1\/4 inch head diameter, and 6 flutes for smooth chip evacuation and a fine surface finish. The straight-cylindrical shank measures 3\/4 inch in diameter for secure chuck engagement. Cobalt steel construction provides elevated heat and wear resistance compared to standard high-speed steel, making it suitable for production environments and interrupted cuts.\u003c\/p\u003e\u003cp\u003eThis countersink is intended for metal fabrication, machine shops, and maintenance applications where consistent fastener seating is required. The right-hand cutting direction is compatible with standard drill press and CNC machining setups. With no pilot included, it is typically used in a drill press or milling machine with a work-holding fixture to maintain positional accuracy. It is sold as a single tool and is appropriate for both job-shop and production use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4 inch head diameter for large-diameter countersink applications\u003c\/li\u003e\n\u003cli\u003e90-degree included angle suits standard flathead machine screw seating\u003c\/li\u003e\n\u003cli\u003e6-flute design promotes smooth cutting action and quality surface finish\u003c\/li\u003e\n\u003cli\u003eCobalt steel construction resists heat buildup during extended or high-speed use\u003c\/li\u003e\n\u003cli\u003e3\/4 inch straight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eRight-hand cut for use with conventional clockwise-rotation spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose countersink for use in drill presses, milling machines, and CNC machining centers with a chuck or collet accepting a 3\/4 inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or tool-and-die technician. Power down and lock out the spindle before securing or removing the tool from the chuck or collet. Use appropriate work-holding fixtures to prevent workpiece movement, as this tool does not include a pilot for self-centering. Follow shop safety standards and machine manufacturer guidelines for speed and feed selection when working with cobalt steel tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Included\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: SC2190116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694088847666,"sku":"SC2190116","price":126.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc3424bcb77464ac40a197c3b93a7fe7.jpg?v=1788320087","url":"https:\/\/voomisupply.com\/products\/value-collection-sc2190116-countersink-1-1-4-in-90-deg-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
