Built to Series A1148 standards, it features a 0.173-inch diameter, a 130-degree split point, and a parabolic flute geometry that promotes fast chip evacuation and reduced heat buildup. The straight-cylindrical shank fits standard drill chucks without modification. Web thinning and a tapered web configuration reduce entry force and improve centering accuracy. Licensed machinists, maintenance mechanics, and fabrication professionals commonly use this bit where precision hole sizing and tool longevity are priorities.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling cast iron, stainless steel, hard materials, non-ferrous metals, and general steel stock. The screw machine length format  -  shorter overall length for improved rigidity  -  makes it a practical choice for CNC machining centers, turret lathes, and production drilling fixtures where chatter and deflection must be minimized. It is equally applicable in manual drill press setups requiring tight hole-diameter tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.173-inch (wire size 17) diameter with a tolerance of -0.00071 to 0.00000 inches for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e130-degree split point reduces walking and lowers required thrust force\u003c\/li\u003e\n\u003cli\u003eParabolic 2-flute design promotes aggressive chip removal and reduced friction\u003c\/li\u003e\n\u003cli\u003eCobalt vanadium HSS construction improves heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration for easier penetration in tough materials\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish; right-hand cut; no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length drill bit compatible with primary workpiece materials including cast iron, hard material, non-ferrous metal, stainless steel, and steel.

Always secure the workpiece and confirm chuck grip before starting the spindle. Verify machine RPM is appropriate for the workpiece material and bit diameter before drilling. Inspect the cutting edges for wear or chipping before each use and replace the bit if damage is detected.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.173 inches (Wire Size 17)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-9\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0401 inches\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: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Vanadium High Speed Steel\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO, BS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1148\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.00071 to 0.00000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER-TITEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5057058\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51784058044722,"sku":"5057058","price":62.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_31788576-af0b-4861-929b-d92cfed058be.jpg?v=1789197532","url":"https:\/\/voomisupply.com\/products\/walter-titex-5057058-screw-machine-drill-bit-0-173-in","provider":"Voomi Supply","version":"1.0","type":"link"}
