Built from high speed steel with a bright, uncoated finish, this bit features a 135-degree split point for fast, self-centering entry with minimal walking. The parabolic flute geometry improves chip evacuation during deep-hole drilling, reducing heat buildup and extending tool life. With a straight-cylindrical shank measuring 0.2950 inches in diameter and an overall length of 4.375 inches, it seats securely in standard drill chucks. This is a production-grade bit suited for machinists, pipefitters, ironworkers, and maintenance technicians who regularly drill steel alloy and similar ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThe 68981 is designed for drilling steel alloy workpieces in industrial, commercial, and heavy-duty shop environments. It fits into standard jobber-length drilling applications where a 0.2950-inch hole is required without the need for coolant-through tooling. The Series 150DH designation places this in a heavy-duty performance tier, making it appropriate for use in drill presses, CNC machines, and hand-held power drills where consistent, repeatable hole quality is the priority. It is sold individually, making it a practical option for single-bit replacement or stocking specific letter sizes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter M sizing at 0.2950 inch decimal equivalent for precise hole specification\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust force and eliminates the need for a center punch on most applications\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile promotes aggressive chip evacuation and reduces clogging during deeper cuts\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides heat resistance and toughness in steel alloy drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration lowers cutting resistance at the chisel edge\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or stock addition for any application requiring a Letter M jobber length drill bit with a straight-cylindrical shank; compatible with standard 3-jaw drill chucks on drill presses, hand-held power drills, and CNC drilling operations targeting steel alloy and comparable ferrous workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tradespersons familiar with rotary cutting tool safety. Secure the shank fully in the drill chuck and verify zero runout before beginning the cut. Always power down and de-energize the drilling machine before changing bits. Cutting fluid or coolant is not required for this bit but may be applied externally to extend tool life when drilling harder steel alloys at high feed rates.\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: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2950 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Finish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 3.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2950 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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150DH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 68981\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51755235934514,"sku":"68981","price":15.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55fdc43f36f3069824c800fd6e21a00c.jpg?v=1788952486","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-68981-jobber-drill-bit-letter-m-0-295-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
