Built from high speed steel with an oxide coating, it delivers general-purpose performance in ferrous metals including cast iron and steel. The 118-degree standard point angle provides a balanced entry with minimal walking on flat stock. At 1.125 inches overall length with a 0.3125-inch flute, this bit is sized for close-clearance drilling tasks where compact tooling is required. Licensed HVAC, plumbing, electrical, and mechanical contractors reach for wire gauge bits like this when drilling small pilot holes, sensor ports, or wiring pass-throughs in sheet metal and structural steel.\u003c\/p\u003e\n\u003cp\u003eThe 44142 is intended for general-purpose drilling in cast iron and steel. Its straight-cylindrical shank seats directly into standard drill chucks and collet holders without adapters. The regular spiral flute geometry and tapered web configuration support chip evacuation in through-hole applications. This bit is suited to benchtop drill presses, hand drills, and CNC drilling fixtures where a wire size 72 diameter is specified. It conforms to DIN 338 standards, making it a recognized format for trade and industrial use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 72 at 0.0250 inches diameter for precision small-hole work\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles cast iron and steel without dedicated coolant\u003c\/li\u003e\n  \u003cli\u003eOxide coating provides surface hardness and basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry on flat and curved stock\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design aids chip clearance and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet systems\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for general-purpose drilling in cast iron and steel workpieces.

Use the lowest practical feed rate for hand drilling to avoid snapping the bit under lateral load. Coolant is not required per design specification, but a light cutting oil improves hole quality and extends tool life in steel. Always wear appropriate eye protection and ensure the workpiece is clamped before beginning the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 72\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.8125 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: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish \/ Coating\u003c\/strong\u003e: Oxide\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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\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: 44142\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51749357027634,"sku":"44142","price":38.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1eca19afe150757905f09246344639f8_c5f7f4ef-4b02-4162-af2c-c66c1b99beaa.jpg?v=1788904918","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-44142-wire-size-72-jobber-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
