It features a 3\/8 inch (9.53 mm) head diameter with a 90-degree included angle and a straight-cylindrical 1\/4 inch shank. The bright, uncoated finish is standard for this carbide tool. Solid carbide construction provides rigidity and wear resistance suited to high-speed cutting in ferrous and non-ferrous metals. This is a single-end tool without a pilot, making it appropriate for use in a drill press, CNC machining center, or hand-held drill with appropriate fixturing.\u003c\/p\u003e\n\u003cp\u003eThe 706-3750-090 is suited for countersinking operations across a range of common metalworking materials including alloy steel, low-carbon steel, medium-carbon steel, cast iron, aluminum, and cast aluminum. The 90-degree included angle matches standard flat-head fastener geometry, making it a practical choice for machine shops, manufacturing facilities, and maintenance environments where precise, consistent chamfers are required across production or repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle sized for standard flat-head fastener countersink profiles\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch (9.53 mm) head diameter with a straight-cylindrical 1\/4 inch shank\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eSingle-end, no-pilot design for use across drill presses, CNC machines, and hand-held drilling equipment\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose metalworking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in alloy steel, low-carbon steel, medium-carbon steel, cast iron, aluminum, and cast aluminum.

Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool from the collet or chuck. Secure the 1\/4 inch straight-cylindrical shank firmly in a properly sized collet or Jacobs chuck before operation. Always wear appropriate eye protection and follow shop safety protocols when operating cutting tools at speed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/8 inch (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Cast Aluminum, Cast Iron, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 706-3750-090\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51751042089266,"sku":"706-3750-090","price":79.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b953ce6a9a29705e6ca795c67938cf29_4b442e2b-b752-4c85-b58f-887dd774838b.jpg?v=1788921344","url":"https:\/\/voomisupply.com\/products\/osg-706-3750-090-countersink-3-8-in-90-deg-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
