Built from cobalt high-speed steel with a bright, uncoated finish, this tool handles the drilling and countersinking steps simultaneously, reducing setup time and improving consistency. The body diameter measures 5\/16 inches, the drill point diameter is 1\/8 inch, and the 118-degree drill point angle is standard for cutting into steel, stainless, cast iron, and other hard materials. Overall length is 2-1\/8 inches. The 60-degree included angle on the countersink portion seats standard flathead fasteners flush.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is suited for machine shops, maintenance technicians, and fabricators working on ferrous and non-ferrous metals. The right-hand cutting direction is compatible with standard drill press and CNC spindle rotation. Its double-end design and plain cutting edge style make it a reliable general-purpose tool for countersinking screw seats, deburring holes, and chamfering edges on workpieces where flathead or countersunk hardware must sit flush. The cobalt construction provides added heat and wear resistance compared to standard HSS tooling, making it a practical choice for production environments or harder alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for improved heat resistance and extended tool life in hard metals\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle for efficient penetration into steel and ferrous alloys\u003c\/li\u003e\n\u003cli\u003e60-degree included angle seats standard countersunk flathead fasteners flush\u003c\/li\u003e\n\u003cli\u003e5\/16-inch body diameter with 1\/8-inch drill point for size 4 screw applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, compatible with standard drill press and CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eDouble-end style for extended service life before replacement\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard combo drill countersink for use with size 4 fasteners requiring a 60-degree countersunk seat in metal fabrication and machining applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed in a standard drill chuck or collet by a machinist or maintenance technician. Secure the shank firmly before operation and confirm spindle rotation is set to right-hand before engaging the workpiece. Use appropriate cutting fluid when working with harder alloys to extend tool life and maintain dimensional accuracy. Inspect the cutting edges for wear before each use and replace if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 23241603\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BC04P0004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690377281842,"sku":"BC04P0004","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0eb8fd5f973377ade62cefe758c2c266.jpg?v=1788269581","url":"https:\/\/voomisupply.com\/products\/value-collection-bc04p0004-combo-drill-countersink-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
