Built from high-speed steel, this right-hand countersink features a 3\/8 inch cutter diameter, a 90-degree included angle, and a 45-degree centerline angle. The adjustable depth collar, measuring 1\/4 inch in thickness, allows the operator to set consistent countersink depth across repeated operations without re-measuring. With a cutter head length of 3\/4 inch, it is suited for use in production environments and field fabrication work where repeatable results are required.\u003c\/p\u003e\u003cp\u003eThis countersink is used in applications requiring clean, accurately angled seat profiles for flathead fasteners in metal fabrication, woodworking, and light manufacturing. Compatible with standard drill configurations accommodating up to 12 drill bit sizes, it fits into typical drill press, hand drill, and CNC drill setups. Its adjustable collar makes it a practical choice for sheet metal work, cabinetry, and structural assembly where consistent countersink depth is critical across multiple workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAdjustable depth collar allows repeatable countersink depth settings without re-measuring\u003c\/li\u003e\n\u003cli\u003e3\/8 inch cutter diameter with 90-degree included angle for standard flathead fastener seating\u003c\/li\u003e\n\u003cli\u003e45-degree centerline angle for proper tool alignment during operation\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across metal and wood substrates\u003c\/li\u003e\n\u003cli\u003e1\/4 inch collar thickness for secure depth stop engagement\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation compatible with standard drill rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with drills accommodating up to 12 standard drill bit sizes.

Always power down and fully secure the workpiece before tool changes or depth collar adjustments. Ensure the collar locking mechanism is tight before beginning any cut to prevent unintended depth variation. Follow applicable shop safety standards and wear appropriate eye protection when operating countersinking tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Cutter Diameter\u003c\/strong\u003e: 1\/2 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\u003eCutter Head Length\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollar Thickness\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Compatibility\u003c\/strong\u003e: 12 drill sizes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth Adjustment\u003c\/strong\u003e: Adjustable\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VERNON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CCH-CCH1890\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VERNON","offers":[{"title":"Default Title","offer_id":68295267615026,"sku":"CCH-CCH1890","price":49.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eea9da65f3dd0c3e6e627e7bd148df58.jpg?v=1793696453","url":"https:\/\/voomisupply.com\/products\/vernon-cch-cch1890-adjustable-depth-drill-countersink","provider":"Voomi Supply","version":"1.0","type":"link"}
