Built from cobalt high-speed steel and finished with a TiAlN coating, this bit handles harder workpiece materials and elevated cutting temperatures better than standard HSS tooling. The split point tip at 135 degrees reduces walking and enables drilling without a center punch on most materials. At 1.75 inches overall length with a 0.75-inch flute, this stub-length geometry provides rigidity and resistance to deflection during drilling operations.\u003c\/p\u003e\u003cp\u003eThis bit is suited for metalworking environments where reduced drill length improves rigidity in drill presses, CNC machines, and hand-held power tools working in confined spaces. The wire gauge size 46, equivalent to 0.0810 inches decimal diameter, is a common dimension in precision hole drilling for fastener clearances, tapping pre-drill operations, and small-diameter through-hole work in steel, stainless steel, cast iron, and other ferrous alloys. Right-hand spiral fluting provides standard chip evacuation appropriate for most production and maintenance drilling tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for improved heat and wear resistance versus standard HSS bits\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in ferrous and hard alloy materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust force and eliminates walking on entry\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides enhanced rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web for improved chip flow and reduced cutting resistance\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement drill bit for wire gauge size 46 applications in standard drill chucks and collet systems accepting a straight-cylindrical shank at 0.0810 inches diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine fully powered down and any rotational motion completely stopped before inserting or removing the bit from the chuck or collet. Machinists and toolroom technicians should verify chuck or collet capacity matches the shank diameter before securing the bit. Use appropriate cutting fluid or coolant for the workpiece material when drilling ferrous alloys to maximize tool life, noting this bit does not support coolant-through capability. Inspect the cutting edges and coating for wear or chipping before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0810 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 23241635\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: 74132432\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739524432178,"sku":"74132432","price":43.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3548e337b637a9154ea328d869187c4d.jpg?v=1788815703","url":"https:\/\/voomisupply.com\/products\/hertel-74132432-screw-machine-drill-bit-size-46-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
