Manufactured from vanadium high speed steel with a WD1 coating, this bit holds a cutting edge longer than standard HSS under heat and friction. The 120-degree split point (S-thinned web) reduces thrust force and allows self-centering on contact, eliminating the need for a center punch in most setups. The straight-cylindrical shank measures 6.00 mm in diameter, compatible with standard drill chucks. Overall length is 101 mm (approximately 3.98 inches) with a 57 mm (approximately 2.24 inches) flute length. The bit weighs 0.035 pounds. Machinists, maintenance technicians, and metalworking professionals are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling blind holes, cross holes, and through holes in steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate. The regular spiral flute geometry handles chip evacuation efficiently in these materials. It fits into standard jobber-length setups on drill presses, CNC machines, and hand-held power drills. The 7\/32-inch (0.2188-inch decimal) diameter falls within the 0.2000 to 0.2500-inch size range, making it a direct fit for applications calling out that fractional size. No coolant-through capability is present, so external coolant or cutting fluid should be used when drilling harder alloys at higher feeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVanadium high speed steel construction with WD1 coating for extended tool life in metal drilling\u003c\/li\u003e\n\u003cli\u003e120-degree S-thinned split point enables self-centering and reduces entry thrust\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0 to minus 0.018 mm supports close-tolerance hole applications\u003c\/li\u003e\n\u003cli\u003eRated for blind hole, cross hole, through-hole, and self-centering drilling operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Compatible with any standard drill chuck accepting a 6.00 mm straight-cylindrical shank. Suitable for drill presses, hand-held power drills, and CNC equipment in the 0.2000 to 0.2500-inch drill diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the straight shank fully in the drill chuck before operation and verify concentricity if using in a CNC or drill press application. Power down and de-energize any machine tool before changing bits. External cutting fluid is recommended when drilling harder steels or aluminum alloys since this bit does not support coolant-through delivery. Follow applicable OSHA and machine-tool manufacturer guidelines for spindle speed and feed rate selection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Inch)\u003c\/strong\u003e: 7\/32 inches (0.2188 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 5.56 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 101 mm (approximately 3.98 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 57 mm (approximately 2.24 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm straight-cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.035 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WD1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: S-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, S-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0 to minus 0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Alloy Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Drilling, Self-Centering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1650\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 16535715\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728769712434,"sku":"16535715","price":79.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b86cba55a58ae73f145fefc0bbdb8ce0_85df58d0-9b0f-4cb1-9854-7f2a1c5290e6.jpg?v=1788696049","url":"https:\/\/voomisupply.com\/products\/osg-16535715-jobber-drill-bit-7-32-inch-hss-wd1","provider":"Voomi Supply","version":"1.0","type":"link"}
