Manufactured from M42 cobalt high-speed steel, this bit handles elevated heat and hard materials that would wear standard HSS tooling prematurely. The 17\/64 inch (0.2656 inch decimal) diameter bit features a 135-degree split point that self-centers on contact, reducing the need for a center punch on most surfaces. Overall length is 6.25 inches with a 3.875-inch parabolic flute that evacuates chips aggressively and reduces heat buildup during deep-hole drilling. Machined to ASME B94.11M and DIN 340 standards, this bit meets recognized dimensional and performance benchmarks for professional tooling.\u003c\/p\u003e\u003cp\u003eThe C16789 is rated for drilling aluminum, brass, carbon steel, cast iron, nickel alloy, plastic, stainless steel, and tool steel. The taper length body provides additional reach compared to jobber-length bits, making it well suited for structural steel fabrication, HVAC equipment assembly, mechanical contractors, and industrial maintenance work where access depth matters. The straight shank with a 0.2656-inch diameter fits standard 3-jaw drill chucks without adapters. Right-hand cut geometry is compatible with conventional drilling equipment used across most trades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat resistance and extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point self-centers and reduces thrust force, minimizing walking on metal surfaces\u003c\/li\u003e\n\u003cli\u003eParabolic flute profile promotes fast chip evacuation and reduces heat buildup in deep holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design lowers cutting resistance and improves penetration rate\u003c\/li\u003e\n\u003cli\u003eTaper length body (6.25 inches OAL) provides extra reach beyond standard jobber-length bits\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and DIN 340 dimensional standards; diameter tolerance held to +0.0000 to -0.0010 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-shank drill chucks; compatible with drilling operations in aluminum, brass, carbon steel, cast iron, nickel alloy, plastic, stainless steel, and tool steel as specified by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists, millwrights, or trade professionals familiar with rotary cutting tools and drill press or handheld drilling equipment. Secure the workpiece firmly before drilling and ensure the chuck is fully tightened on the straight shank before operation. Apply appropriate cutting fluid for the material being drilled, particularly when working stainless steel or nickel alloy, to extend bit life and maintain dimensional accuracy. Inspect the cutting edges for wear or chipping before each use and replace the bit if the split point or flute edges show damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2575\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 17\/64 inches (0.2656 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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 (M42 Grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.25 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: 0.2656 inches (6.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.375 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Grade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 340, DIN 338\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\u003eWeight\u003c\/strong\u003e: 0.9 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: C16789\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51700983824690,"sku":"C16789","price":58.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/314291eb4ffc1e9afba9865633e46c7a_ab92c452-560b-4ca5-b4e0-ed89ea9adc87.jpg?v=1788396293","url":"https:\/\/voomisupply.com\/products\/cleveland-c16789-taper-length-drill-bit-17-64-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
