Designed for production and maintenance drilling where a longer reach is required than a jobber-length bit provides, this bit features a parabolic flute geometry that improves chip evacuation and reduces heat buildup during cutting. The bright, uncoated finish suits general-purpose applications across a wide range of materials. Right-hand cutting action and a tanged shank keep the bit seated during aggressive feeds. It conforms to ASME B94.11M standards.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for machine shop, fabrication, and maintenance applications requiring a longer flute to reach deeper holes. The parabolic flute design performs well in softer metals, carbon steel, alloy steel, stainless steel, copper alloys, aluminum, and other non-ferrous metals. It is intended for use in drill presses, CNC machining centers, and hand-held equipment with appropriate chuck adapters. The taper length body gives additional clearance when drilling into recessed or deep-pocket features.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter E (0.250 inch) diameter with a tolerance of +0.0000 to -0.0007 inches\u003c\/li\u003e\n\u003cli\u003e118-degree notched point for positive engagement and reduced walking\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry for efficient chip removal in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design reduces thrust and improves penetration\u003c\/li\u003e\n\u003cli\u003eBright, uncoated HSS construction — no coating to flake in high-heat applications\u003c\/li\u003e\n\u003cli\u003eTanged shank provides positive drive and resists slippage in drill sleeves\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B94.11M dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style taper length drill bit compatible with standard drill sleeves, chucks, and spindles that accept a 0.250-inch tanged shank.

Secure the bit fully in the chuck or drill sleeve before operation and verify runout is within acceptable limits. Power down and de-energize the machine before changing tooling. Do not exceed the recommended feed and speed parameters for the workpiece material and bit diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2565\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.250 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\u003ePoint Type\u003c\/strong\u003e: Notched\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Tanged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.375 inches\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: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: C16070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695699624242,"sku":"C16070","price":165.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f5a3d27ec4411c2b6f8ef44dd7c58da_d6dab920-fee6-497f-8a0f-943e5f10fa5a.jpg?v=1788337547","url":"https:\/\/voomisupply.com\/products\/cleveland-c16070-taper-length-drill-bit-letter-e-0-25-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
