Built to Series 2133 standards, it carries a wire gauge size of 43, which corresponds to a decimal diameter of 0.0890 inches. The 135-degree split point reduces walking on entry and decreases the thrust needed to start a hole. At 1.75 inches overall length, this short-flute geometry improves rigidity and reduces deflection. The M42 cobalt construction handles elevated cutting temperatures better than standard high-speed steel, making it suitable for interrupted cuts and harder workpiece materials. Licensed machinists, toolroom technicians, and production drill press operators are the primary installers and users.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling alloy steels and aluminum in screw machine operations, CNC drilling fixtures, and bench drill press setups where stub-length rigidity is required. The right-hand spiral flute and web-thinned parallel web configuration promote chip evacuation in blind and through-hole applications. The straight cylindrical shank with a 0.0890-inch shank diameter seats directly into standard drill chucks and collet holders without adapters. Production shops running tight-tolerance hole patterns will benefit from the diameter tolerance of plus 0.0000 to minus 0.0005 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for heat resistance and durability in alloy and aluminum drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry walking and lowers required thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web improves chip flow and reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length of 1.75 inches overall increases rigidity and reduces deflection\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of plus 0.0000 to minus 0.0005 inches supports close-tolerance hole sizing\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 1897 specifications for consistent dimensional compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for wire size 43 screw machine length drill bits in standard drill chucks and collet systems accepting a 0.0890-inch straight cylindrical shank.

Always wear appropriate eye protection and ensure the workpiece is clamped or fixtured before starting the cut. Follow applicable shop safety codes and manufacturer feed-and-speed recommendations for cobalt tooling in the specific workpiece material. Inspect the cutting edges for chipping or wear before each use and replace the bit when edge condition degrades to avoid oversize or out-of-round holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\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\u003eOverall Length\u003c\/strong\u003e: 1.75 inches (44.45 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0 inches (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.0000 to minus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2133\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 1897 (ANSI\/DIN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C14546\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51708986917170,"sku":"C14546","price":57.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84e4f7b84dbbee269c467a38b2c9277f.jpg?v=1788449633","url":"https:\/\/voomisupply.com\/products\/cleveland-c14546-screw-machine-drill-bit-size-43-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
