It features a 3\/8-inch head diameter, an 82-degree included angle, and a 6-flute cutting geometry that produces clean, consistent countersunk seats with minimal chatter. The 1\/4-inch straight cylindrical shank provides secure chuck engagement on standard drilling equipment. This tool is used by machinists, tool-and-die workers, and fabricators who require repeatable countersink geometry for fastener seating and deburring operations.\u003c\/p\u003e\n\u003cp\u003eThe 336-005060 is suited for countersinking operations in alloy steel, cast iron, and glass-reinforced plastic. The bright uncoated carbide construction handles tough ferrous and composite materials without requiring a pilot for alignment. Its single-end, right-hand cut configuration makes it compatible with conventional drill presses, CNC machining centers, and hand-held power drilling equipment. The 82-degree angle matches the seating geometry for flat-head fasteners commonly specified in structural and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-inch head diameter with 82-degree included angle for flat-head fastener seating\u003c\/li\u003e\n  \u003cli\u003e6-flute design reduces cutting force and produces a smoother finish than single- or 3-flute tools\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in alloy steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch straight cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish with no pilot — single-end, right-hand cut\u003c\/li\u003e\n  \u003cli\u003eRated for alloy steel, cast iron, and glass-reinforced plastic material applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for countersinking operations in alloy steel, cast iron, and glass-reinforced plastic.

Secure the shank fully in the chuck or collet before operation and verify runout before cutting. Power down and de-energize the spindle before tool changes or adjustments. Do not use on materials outside the rated application list, as carbide is brittle and susceptible to edge chipping under impact or side loading.\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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 41 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: 1\/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\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Cast Iron, Glass-Reinforced Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 336-005060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753920266546,"sku":"336-005060","price":54.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf0efb9daf69b81e6354c1735c68cba1.jpg?v=1788942060","url":"https:\/\/voomisupply.com\/products\/hertel-336-005060-countersink-3-8-in-82-deg-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
