The bit features a 118-degree standard point angle and an oxide coating that provides basic surface protection and lubricity during cutting. With a 4.50 mm (0.1772 inch) diameter and an overall length of 3.3906 inches, this drill fits standard straight-shank chucks and is sized for common clearance and through-hole work. The web-thinned, tapered web construction reduces entry resistance and helps maintain center on initiation. Machinists, fabricators, and maintenance technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis jobber drill is suited for drilling steel and cast iron in general-purpose shop and field applications. The regular spiral flute profile handles a wide range of material hardnesses within its intended workpiece category. The 2.2031-inch flute length provides adequate chip clearance for moderate-depth holes typical of structural and mechanical assembly work. At 4.50 mm diameter, this bit falls within the 4.00-5.00 mm size range commonly used for tapping pre-drill, clearance holes for M5 fasteners, and similar metalworking tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4.50 mm (0.1772 inch) diameter with straight-cylindrical shank for universal chuck compatibility\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose steel and cast iron drilling\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide coating for basic wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces thrust required on entry\u003c\/li\u003e\n\u003cli\u003eRegular right-hand spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e2-flute design compatible with standard drill press and handheld electric drill use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill for use in straight-shank chucks accepting 0.1772-inch shank diameter bits, suitable for drilling steel and cast iron workpieces in typical shop and maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and removed by a licensed machinist, tooling technician, or qualified maintenance professional using a keyed or keyless drill chuck. Secure the shank fully in the chuck before operation and verify the workpiece is clamped or fixtured to prevent rotation. Use appropriate cutting fluid or coolant when drilling steel at sustained depth to extend tool life. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.50 mm (0.1772 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.3906 inches (86.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.2031 inches (56.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1772 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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: Regular 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\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0239 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01244508\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711625560370,"sku":"01244508","price":35.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6adcd08578df5da743b0f7daa8f0379.jpg?v=1788477783","url":"https:\/\/voomisupply.com\/products\/value-collection-01244508-4-50mm-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
