Built with a 90-degree included angle and a 3\/16-inch head diameter, it is sized for small-diameter fastener preparation where precision seating is required. The straight cylindrical shank allows direct chuck mounting without adapters. Machinists, tool-and-die technicians, and maintenance mechanics use this countersink for deburring, chamfering, and countersinking operations on the bench or under power.\u003c\/p\u003e\u003cp\u003eThis countersink is well suited for light-duty production and maintenance applications requiring a compact 3\/16-inch cutting diameter. The 6-flute geometry distributes cutting load evenly, reducing chatter on thin-gauge sheet metal and close-tolerance work. It is appropriate for use in drill presses, CNC machining centers, and hand-held drill motors where a consistent 90-degree seat angle is needed for flat-head fastener installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree included angle for standard flat-head fastener countersinking\u003c\/li\u003e\n\u003cli\u003e6-flute design reduces chatter and produces a smooth seat finish\u003c\/li\u003e\n\u003cli\u003e3\/16-inch head diameter sized for small fastener applications\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for direct chuck mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-piece countersink compatible with any drill press, CNC machining center, or hand drill accepting a straight cylindrical shank in the corresponding collet or chuck size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician. Secure the workpiece fully before operation and confirm the chuck or collet is tightened to the tool manufacturer specification before starting the spindle. Use appropriate cutting fluid for ferrous materials to extend tool life and maintain seat finish quality. Inspect the cutting edges before each use and replace the tool if chipping or excessive wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 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 Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\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: 18295\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733442363698,"sku":"18295","price":72.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80094f89f226a35f33fb7f92234d89f8.jpg?v=1788755509","url":"https:\/\/voomisupply.com\/products\/hertel-18295-countersink-3-16-in-90-degree-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
