It carries a wire gauge size of 43, equivalent to 0.0890 inches in decimal diameter. The 135-degree split point starts on contact without a center punch and reduces walking on hard surfaces. Made from M42 cobalt high-speed steel, this bit handles the heat generated when drilling stainless steel, nickel alloy, tool steel, and other tough materials. The parabolic flute geometry clears chips efficiently, reducing the need to peck-drill in deeper holes. The straight shank fits standard drill chucks without an adapter.\u003c\/p\u003e\u003cp\u003eThis bit is suited for machine shop, fabrication, and maintenance applications where standard jobber-length bits lack the reach needed for deeper holes. The taper length body extends cutting depth compared to a standard jobber bit while still fitting a straight-shank chuck. It is appropriate for use in CNC drill presses, knee mills, and hand-held power drills on materials including aluminum, brass, carbon steel, cast iron, nickel alloy, plastic, stainless steel, and tool steel. It is a common choice for machinists, pipefitters, ironworkers, and maintenance mechanics.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat resistance in hard-material drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering starts and reduced thrust\u003c\/li\u003e\n\u003cli\u003eParabolic flute profile for fast chip evacuation in deep holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned and tapered web configuration reduces cutting resistance\u003c\/li\u003e\n\u003cli\u003eTaper length body provides extended reach beyond standard jobber length\u003c\/li\u003e\n\u003cli\u003eStraight shank accepts standard drill chucks with no adapter needed\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and DIN 340 standards; classified per DIN 338\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a heavy-duty OEM-style taper length drill bit compatible with any straight-shank drill chuck sized for a 0.0890-inch shank diameter.

Apply appropriate cutting fluid when drilling stainless steel, nickel alloy, or tool steel to extend bit life and reduce heat buildup. Do not exceed the recommended RPM range for the bit diameter and material being drilled. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: M42 Cobalt High-Speed Steel\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 Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Brass, Carbon Steel, Cast Iron, Nickel Alloy, Plastic, Stainless Steel, Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C16766\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51698900042034,"sku":"C16766","price":41.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/314291eb4ffc1e9afba9865633e46c7a_280dcd00-7f30-40f2-bc94-c3f43b6cb164.jpg?v=1788369611","url":"https:\/\/voomisupply.com\/products\/cleveland-c16766-taper-length-drill-bit-wire-43-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
