Built from high speed steel (HSS) with a coated finish, this bit carries a 135-degree split point that reduces walking and allows drilling to begin without a center punch. The shortened screw machine length body provides added rigidity over jobber-length bits, making it well suited for drill press and CNC turret work where chatter and deflection are concerns. Two spiral flutes with regular helix and web-thinned, parallel-web construction support efficient chip evacuation and reduced thrust in tougher materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for metalworking applications in both shop and field settings. It is most commonly used by machinists, tool-and-die tradespeople, and maintenance technicians drilling cast iron and steel in manufacturing, fabrication, and industrial maintenance environments. The straight cylindrical shank fits standard drill chucks. At wire size 18 (0.1695 inches), it handles smaller-diameter through-holes and tapped hole preparation at common fastener sizes. It meets NAS 907 and ISO standards, making it appropriate for aerospace and precision manufacturing work where specification compliance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces bit walking and lowers thrust force on entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web improves chip flow and reduces heat buildup in the cutting zone\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body increases rigidity compared to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended service life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for standard drilling operations\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 and ISO specifications for use in controlled manufacturing environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling selection for screw machine, drill press, and CNC turret applications drilling cast iron and steel workpieces requiring a wire size 18 diameter hole.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with metal drilling operations. Secure the workpiece and verify chuck grip on the straight cylindrical shank before operation. Verify spindle speed is appropriate for the workpiece material and bit diameter before engaging the cut. Inspect the cutting edges and coating condition before each use and replace bits showing chipping, heat discoloration, or dimensional wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1695 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0625 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\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: 2159\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO, NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 48388\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51728359948594,"sku":"48388","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a1bf246951cb5e8d40314e2e48d6071.jpg?v=1788690641","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48388-screw-machine-drill-bit-0-1695-in","provider":"Voomi Supply","version":"1.0","type":"link"}
