It measures 0.3937 inches in diameter with a 118-degree standard point angle and a right-hand spiral flute configuration. The bit is manufactured from high-speed steel with a bright uncoated finish. Overall length is 5.2362 inches (133 mm), and the straight-cylindrical shank matches the drill diameter at 0.3937 inches. A web-thinned, tapered-web design reduces thrust at entry and improves chip evacuation. This bit is installed by machinists, maintenance technicians, and mechanical contractors using standard drill chucks.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and maintenance drilling in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The 9xD flute-to-diameter ratio and 3.4252-inch flute length support drilling to a maximum depth of 3.4252 inches, making it appropriate for through-hole and blind-hole applications in both shop and field settings. It conforms to DIN 338 and ANSI standards and is classified under Series 2A for general-purpose performance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.3937-inch diameter with matching straight-cylindrical shank for secure chuck engagement\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose entry on common metals\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles steel, stainless steel, cast iron, and superalloys\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered-web design reduces drilling thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 9xD ratio supports depths up to 3.4252 inches\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 and ANSI standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a 0.3937-inch straight-cylindrical shank.

Secure the shank fully in the chuck and verify runout before drilling. Apply appropriate cutting fluid when drilling stainless steel, superalloys, or titanium to extend tool life. Inspect the cutting edges and web condition before each use and replace the bit if chipping or excessive wear is present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3937 inches\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: 5.2362 inches (133 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.4252 inches (87 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8110 inches (46 mm)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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: 2A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 338, ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.83 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: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6000678\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699285590322,"sku":"6000678","price":21.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e64fa5b842584bbfb6b1032bddd2a2c4_a6eb4f1a-39be-46a6-98c9-d08cb1e80515.jpg?v=1788374605","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000678-jobber-drill-bit-0-3937in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
