Built with 9 flutes and a 60-degree included angle, it produces clean, accurate seat profiles for fastener heads and deburring tasks. The bright, uncoated finish is suited for use on a range of workpiece materials. With a 0.5-inch shank diameter and an overall length of 2.5 inches, this countersink fits standard drill presses, milling machines, and CNC machining centers. It is intended for use by machinists, tool and die makers, and precision fabricators requiring consistent chamfer geometry.\u003c\/p\u003e\n\u003cp\u003eThis countersink is used in production and job-shop machining environments where countersinking for flat-head screws, deburring drilled holes, and chamfering part edges are routine operations. The 9-flute configuration reduces chatter and improves surface finish compared to lower-flute-count tools. Its right-hand cutting direction is compatible with standard right-hand spindle rotation on drill presses, knee mills, and CNC machining centers. The solid carbide construction provides rigidity and wear resistance in both ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e60-degree included angle for standard flat-head fastener countersinking\u003c\/li\u003e\n  \u003cli\u003e9 flutes for reduced chatter and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction, material grade C2, for rigidity and tool life\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish  -  no coating to interfere with dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, compatible with standard right-hand spindle rotation\u003c\/li\u003e\n  \u003cli\u003e0.5-inch shank diameter fits standard tool holders and collet chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank countersink for use in drill presses, manual milling machines, and CNC machining centers accepting a 0.5-inch round shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by a qualified machinist. Secure the shank firmly in an appropriate collet or drill chuck before operation and verify spindle speed is appropriate for the workpiece material and tool diameter. Always de-energize and lock out the machine before changing tooling. Do not exceed the tool's rated cutting parameters, and inspect the flutes for wear or chipping before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: HTC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HTC","offers":[{"title":"Default Title","offer_id":68355169386802,"sku":"1109","price":123.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60ae3710bc39feb93d17fe0025cc3dba.jpg?v=1793875435","url":"https:\/\/voomisupply.com\/products\/htc-1109-countersink-60-degree-9-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
