It features a 1-1\/4 inch head diameter, a 90-degree included angle (45-degree centerline angle), and 6 flutes that promote smooth chip evacuation and a clean, chatter-free finish. The 3\/4 inch straight-cylindrical shank provides a secure, concentric grip in standard drill press or CNC machine tool holders. This tool ships in a bright, uncoated finish and is configured for right-hand cutting. Machinists and tooling technicians working in production or job-shop environments will find this countersink suited for high-volume or precision applications.\u003c\/p\u003e\n\u003cp\u003eThis countersink is appropriate for creating chamfered seating surfaces for flat-head fasteners in ferrous and non-ferrous materials. The 90-degree included angle is the standard angle for most inch-series flat-head machine screws and bolts per ASME standards. With no pilot and a single-end configuration, it is intended for use in machine setups where the operator controls depth and alignment through the workholding fixture or CNC program rather than a pilot pin. Typical applications include aerospace, automotive, general manufacturing, and maintenance shops requiring consistent countersink geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4 inch head diameter for larger fastener clearances and spot-facing applications\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle matches standard inch-series flat-head fastener geometry\u003c\/li\u003e\n  \u003cli\u003e6-flute design reduces chatter and improves surface finish compared to lower-flute-count tools\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in hard or abrasive materials\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch straight-cylindrical shank fits standard collets and end mill holders\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — ready for use or compatible with aftermarket coating if desired\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a machine-held countersink compatible with drill presses, milling machines, and CNC machining centers equipped with a 3\/4 inch collet or end mill holder.

Power down and lock out the spindle before changing or inspecting the tool. Do not use this countersink as a drill — it is intended for countersinking only and is not rated for axial drilling loads. Follow applicable shop safety standards and machine guarding requirements during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-1\/4 inches\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\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eTool Application\u003c\/strong\u003e: Countersinking\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 336-011070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736555553074,"sku":"336-011070","price":337.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d69e294de6d84f4999323f940d4c51e.jpg?v=1788778657","url":"https:\/\/voomisupply.com\/products\/hertel-336-011070-countersink-1-1-4-in-90-deg-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
