Built from high speed steel with an oxide and gold coating, this bit delivers heat resistance and extended tool life under continuous use. The 137-degree split point reduces walking and thrust at entry, making it a reliable choice for production environments and field work alike. With a right-hand spiral flute and 4.75-inch overall length, it fits standard drill chucks and follows ANSI specifications. Licensed trades and machinists reach for this geometry when consistent hole diameter and clean entry matter.\u003c\/p\u003e\u003cp\u003eThis drill bit suits residential and light commercial applications where a 0.3390-inch diameter hole is required. Typical use cases include pilot holes for fasteners, clearance holes in steel plate, and precision boring in fabrication shops. The jobber-length format makes it compatible with most hand drills, drill presses, and milling machine setups. Maintenance technicians, pipefitters, sheet metal workers, and general contractors keep this size in rotation for its versatility across ferrous and non-ferrous stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter R size: 0.3390 inches decimal equivalent for precise fitment\u003c\/li\u003e\n\u003cli\u003e137-degree split point reduces entry walking and lowers required thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute with 2.375-inch flute length for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eHeavy-duty grade rated for continuous holemaking cycles\u003c\/li\u003e\n\u003cli\u003eThree flats on shank for secure chuck grip and reduced slippage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an ANSI-specification jobber-length drill bit for use in standard 3-jaw drill chucks, drill presses, and compatible CNC or manual milling setups accepting a straight shank in the 0.3000 to 0.3500 inch size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist, tool-and-die worker, or trade professional familiar with rotary cutting tools. Secure the shank firmly in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent rotation. Always wear eye protection and follow applicable ANSI B11 machine safety standards when operating drill presses or handheld drills. Do not exceed the rated speed range for high speed steel tooling in the material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3390 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 137 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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\u003eCoating\/Finish\u003c\/strong\u003e: Oxide \/ Gold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eFlute Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: Jobber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H95006217\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732352270642,"sku":"H95006217","price":18.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a223a45347d1fa5a2ab4c51d73d5f4bc.jpg?v=1788741955","url":"https:\/\/voomisupply.com\/products\/hertel-h95006217-jobber-drill-bit-letter-r-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
