At 15\/64 inch (0.2344 inch) in diameter and 3.875 inches overall length, it delivers accurate, consistent holes in a compact jobber format suited for bench-top drill presses, hand drills, and CNC drilling operations. The bright, uncoated finish keeps the steel at its natural hardness and is well-suited for low-heat, lower-speed applications. Two spiral flutes with a regular helix evacuate chips efficiently across the full 2.625-inch flute length. Machinists, tool-and-die technicians, electricians, and HVAC service techs who need a dependable fractional-letter-size drill for general-purpose hole-making will find this a straightforward, no-frills option.\u003c\/p\u003e\n\u003cp\u003eThe CD40615 is designed for drilling non-ferrous metals including aluminum, copper, brass, and similar soft metallic workpieces. Its right-hand cutting direction and straight cylindrical shank make it compatible with standard three-jaw drill chucks and quick-change holders. The 11xD flute-to-diameter ratio and 2.625-inch maximum drilling depth support through-hole and moderate-depth operations in sheet stock and light structural material. No coolant-through capability is present, so external cutting fluid or dry drilling practices apply based on the material and feed rate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter E size: 15\/64 inch (0.2344 inch) diameter with a tight tolerance of -0.0007 to +0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose drilling on non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction — bright, uncoated finish for low-heat applications\u003c\/li\u003e\n  \u003cli\u003eTwo spiral flutes, regular helix, 2.625 inches flute length for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank (15\/64 inch diameter, 1.25 inches shank length) fits standard chucks\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction; Series CD40 jobber-length format\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber drill for use in standard three-jaw drill chucks and quick-change chuck systems that accept straight cylindrical shanks in the 15\/64 inch diameter range.

Secure the straight cylindrical shank firmly in the chuck and confirm there is no runout before beginning a cut. No coolant-through path is present in this bit, so apply external cutting fluid at the drill point when working with materials that require lubrication to prevent galling or work hardening. Verify spindle speed and feed rate are appropriate for the workpiece material before drilling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 15\/64 inch (0.2344 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2344 inch (15\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0007 to +0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 11xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CD40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CD40615\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51729165254962,"sku":"CD40615","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6108d0f7c98f3ff57935b2361fe2a42_11acf4ab-e704-4117-abc4-7ad79f1373e7.jpg?v=1788701231","url":"https:\/\/voomisupply.com\/products\/titan-usa-cd40615-jobber-drill-bit-letter-e-15-64-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
