With a 100-degree included angle and a 1.5-inch head diameter, it seats flat-head fasteners and prepares hole edges for deburring in a single pass. The straight-cylindrical shank measures 0.75 inches in diameter for secure chuck engagement. The bright uncoated finish is standard for general-purpose HSS tooling. Machinists and tool-and-die professionals install this countersink in drill presses, milling machines, and hand-held power drills where consistent angle and clean finish matter.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for general countersinking operations in machine shops, maintenance facilities, and fabrication environments. Its 100-degree included angle accommodates fastener head profiles that require a wider seat angle than the more common 82-degree or 90-degree tools. The right-hand cutting direction is standard for conventional spindle rotation. No pilot is included, making it appropriate for use where the operator controls centering through fixturing or a pre-drilled pilot hole. Both light production and one-off repair work are typical use cases.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e100-degree included angle for wider flat-head fastener seating\u003c\/li\u003e\n  \u003cli\u003e1.5-inch head diameter for coverage on larger hole entries\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design reduces chatter and produces a smooth finish\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles steel, aluminum, and plastics\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.75 inches fits standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating degradation concerns in moderate-heat applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink for use in standard drill chucks and collets accepting a 0.75-inch straight-cylindrical shank.

Secure the shank fully in the chuck before operation and confirm the workpiece is firmly clamped. Run at reduced RPM compared to standard twist drills of similar diameter to avoid work hardening and premature edge wear. Inspect the cutting edge before each use and do not use a chipped or dull tool, as it will produce an unacceptable finish and can damage the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 100 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 50 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 1\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\u003eIncludes Pilot\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Countersinking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.85 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SC10100132\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698450989362,"sku":"SC10100132","price":101.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f2880c7ced8ed0a4d815a30567e05a6.jpg?v=1788363046","url":"https:\/\/voomisupply.com\/products\/value-collection-sc10100132-countersink-100-deg-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
