Designed for right-hand cutting, the bit features a regular spiral flute, straight-cylindrical shank, and an oxide and TiN coating for extended tool life. Overall length is 4.75 inches with a flute length of 3.4375 inches. The split point geometry reduces walking on entry and lowers thrust requirements, making this bit well-suited for production drilling where positioning accuracy and tool longevity matter.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for cutting stainless steel, superalloys, and titanium — materials that generate high heat and work-harden under tooling pressure. Cobalt construction and the dual-coating combination allow the bit to retain hardness at elevated temperatures. It is appropriate for job shop work, maintenance shops, and field applications where a reliable letter-size drill is needed for tough ferrous and non-ferrous workpiece materials. Coolant-through is not available on this bit, so appropriate surface cutting speeds and chip clearing techniques should be applied when working with difficult alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter Q size at 0.3320 inches decimal diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003eCobalt construction with oxide and TiN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry walking and cutting thrust\u003c\/li\u003e\n\u003cli\u003eRegular right-hand spiral flute with 3.4375-inch flute length for deep chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003e2-flute design optimized for high-temperature alloys including stainless steel and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks accepting a 0.3320-inch straight-cylindrical shank.

Secure the shank fully in the chuck before operation and confirm runout is within acceptable limits for the application. When drilling stainless steel or titanium, maintain consistent feed pressure to avoid work hardening and reduce heat buildup through appropriate cutting speed selection. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: Q\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3320 inches\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\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3320 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0010 to +0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys and Titanium\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\u003eSeries\u003c\/strong\u003e: CD50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: TITAN USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CD50317\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51730199707954,"sku":"CD50317","price":21.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b584f92fd10811fc6227f91047b27a6.jpg?v=1788713198","url":"https:\/\/voomisupply.com\/products\/titan-usa-cd50317-cobalt-jobber-drill-bit-letter-q","provider":"Voomi Supply","version":"1.0","type":"link"}
