It features a 3\/16-inch head diameter, a 60-degree included angle, and a matching 3\/16-inch straight cylindrical shank. The bright, uncoated alloy steel construction delivers solid cutting performance across a range of compatible materials. With a right-hand cutting direction and single-end configuration, this countersink suits precision deburring and fastener seat preparation tasks in production and maintenance environments. No pilot is included, and the tool ships ready for use with standard collet or drill chuck setups.\u003c\/p\u003e\u003cp\u003eThis countersink is suited for shop and field use where controlled countersink depth and clean entry angles are required. It is intended for machining operations involving alloy steel, cast iron, and glass-reinforced plastic workpieces. The straight cylindrical shank allows direct chucking in most standard drill presses, CNC machines, and hand-held power drills equipped with appropriate collets or chucks. It is commonly used by machinists, tool-and-die workers, and maintenance technicians for deburring holes and preparing seating surfaces for flat-head fasteners.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/16-inch head diameter with matching 3\/16-inch straight cylindrical shank\u003c\/li\u003e\n\u003cli\u003e60-degree included angle and 30-degree centerline angle for standard countersink geometry\u003c\/li\u003e\n\u003cli\u003eSingle-flute design for controlled material removal\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for use with conventional drill rotation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect dimensional tolerances\u003c\/li\u003e\n\u003cli\u003eRated for use in alloy steel, cast iron, and glass-reinforced plastic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for countersinking operations in alloy steel, cast iron, and glass-reinforced plastic workpieces.

Secure the shank firmly before operation and verify spindle speed is appropriate for the workpiece material and tool diameter. Always power down and lock out the machine before changing tooling. Do not exceed the tool's rated material applications to avoid premature wear or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 30 degrees\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eShank Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 331-002050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748308123954,"sku":"331-002050","price":30.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c202c2c4c6cd3e4cbf68afc76ae56fc9.jpg?v=1788892169","url":"https:\/\/voomisupply.com\/products\/hertel-331-002050-countersink-3-16-in-60-degree-1-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
