Built to standard jobber proportions, it delivers a balance of rigidity and reach suited to bench-mounted drill presses and handheld power drills alike. The 118-degree standard point angle provides reliable self-centering on flat and curved surfaces without requiring a pilot hole in most applications. At 1\/4 inch diameter with a straight shank, it seats directly into standard three-jaw chucks and quick-change bit holders used across mechanical, electrical, and plumbing trades.\u003c\/p\u003e\u003cp\u003eThis bit is a shop and field staple for electricians drilling knockout-size pilot holes, plumbers clearing fastener paths through light framing, and HVAC technicians mounting brackets and controls. The jobber length format — 4 inches overall with 2.75 inches of flute — fits standard drill chucks without the overhang concerns associated with longer aircraft-extension bits. Suitable for light-to-medium production drilling in trade shop environments and on-site service calls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh speed steel construction resists heat buildup during continuous drilling cycles\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for reliable starting on flat and contoured surfaces\u003c\/li\u003e\n\u003cli\u003eJobber length proportions balance reach and lateral stiffness\u003c\/li\u003e\n\u003cli\u003eStraight shank compatible with standard three-jaw chucks and quick-change holders\u003c\/li\u003e\n\u003cli\u003e1\/4 inch diameter fits common knockout and fastener clearance applications across trades\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber length drill bit for use in any three-jaw drill chuck or quick-change driver system accepting a straight 1\/4 inch shank bit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstalled and operated by electricians, plumbers, HVAC technicians, and general mechanical trades. Secure the workpiece before drilling and confirm the chuck is fully tightened around the straight shank before applying power. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat. Dispose of worn bits per shop safety protocols — dull HSS bits increase torque load and risk workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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\u003eLength Style\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 042526605161\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IRWIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: IR60516\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51347783778610,"sku":"IR60516","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310499680.jpg?v=1782113669","url":"https:\/\/voomisupply.com\/products\/irwin-ir60516-hss-jobber-drill-bit-1-4-inch-118-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
