Built from high speed steel with a titanium nitride (TiN) coating, it delivers extended cutting life compared to uncoated HSS tooling. The 135-degree split point reduces walking on entry and lowers thrust requirements, making it effective on both dedicated drill presses and handheld equipment. At 5 inches overall length with a 3-5\/8-inch flute length, the bit handles standard jobber-length drilling tasks across a range of ferrous and non-ferrous workpieces. This is a right-hand, two-flute design with a straight-cylindrical shank sized at 0.3770 inches.\u003c\/p\u003e\u003cp\u003eSuited for general-purpose holemaking in industrial, mechanical, and trade settings, this bit fits standard drill chucks without adapters. The 0.3770-inch decimal equivalent of letter V makes it appropriate for through-holes, clearance holes, and tap-preparation applications where a precise diameter in the 0.3500 to 0.4000 inch range is required. Typical users include machinists, millwrights, HVAC fabricators, pipefitters, and maintenance technicians working with steel plate, structural members, or sheet metal assemblies. The heavy-duty grade designation indicates suitability for more demanding feed and speed conditions than standard jobber bits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter V size, 0.3770 inches decimal equivalent for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and minimizes drill walking on entry\u003c\/li\u003e\n\u003cli\u003eTiN coating extends tool life and reduces friction during cutting\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles a broad range of metals\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration lowers cutting resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber drill bit compatible with any standard drill chuck or collet accepting a 0.3770-inch straight-cylindrical shank.

Secure the workpiece fully before drilling and ensure the chuck is tightened to the shank before operation. Follow machine manufacturer guidelines for appropriate spindle speeds and feed rates based on material type and thickness. Inspect the cutting edges for wear or chipping before each use, and replace the bit when point geometry is compromised to maintain hole quality and prevent tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3770 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3770 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: NAS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 66693953\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739322712370,"sku":"66693953","price":23.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73e8859e4b00db3578a34b621925dfd5.jpg?v=1788813132","url":"https:\/\/voomisupply.com\/products\/hertel-66693953-jobber-drill-bit-letter-v-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
