Built from solid carbide and finished with an AlTiN coating, this tool handles demanding materials including hardened steels, stainless, and high-temp alloys. The 1\/8 inch body diameter and 3\/64 inch drill point deliver a 90-degree included angle with a 118-degree drill point angle. With an overall length of 1-1\/2 inches, the compact form factor suits both CNC machining centers and manual drill press operations where tool runout and rigidity are critical.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is used in metal fabrication, toolroom, aerospace, and general machining environments where operators need accurate center location and countersink geometry in one pass. Trade size 1 positions it for light-duty center drilling tasks on small-diameter workpieces. Right-hand cutting direction matches standard spindle rotation on conventional milling machines and drill presses. The double-end configuration extends usable tool life by providing two cutting ends per shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and extends tool life in dry or minimal-lubrication cutting\u003c\/li\u003e\n\u003cli\u003e90-degree included angle with 118-degree drill point angle for standard countersink geometry\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two usable cutting ends per tool\u003c\/li\u003e\n\u003cli\u003eRight-hand cut for use with standard CNC and manual spindle rotation\u003c\/li\u003e\n\u003cli\u003eCompact 1-1\/2 inch overall length reduces deflection in tight setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement combined drill and countersink suitable for standard toolholders and collet chucks accepting a 1\/8 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this tool should be performed by a qualified machinist familiar with cutting tool setup and speeds-and-feeds selection for carbide tooling. Secure the shank fully in a collet or toolholder rated for the shank diameter before running the spindle. Inspect the cutting edges for chipping before each use, as solid carbide is brittle and sensitive to interrupted cuts or improper clamping. Follow machine manufacturer guidelines and applicable shop safety standards when operating rotating cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Diameter\u003c\/strong\u003e: 3\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 3\/64 inches (0.047 inches \/ 1.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches\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: Double\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17930-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51740676325682,"sku":"17930-C3","price":47.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df018f77dd3913277b297d0102946953.jpg?v=1788826651","url":"https:\/\/voomisupply.com\/products\/harvey-tool-17930-c3-combo-drill-countersink-1-8-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
