The stub-length body is shorter than a jobber drill, which reduces deflection and improves rigidity in CNC machines, drill presses, and screw machine applications. The cutting diameter is 0.1285 inches with a flute length of approximately 15\/16 inches and an overall length of approximately 1-15\/16 inches. This bit is suited for production drilling in metal fabrication shops and machine shops where hole accuracy and tool life matter.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in screw machines, turret lathes, machining centers, and drill presses where a short, rigid tool is required. Its reduced length minimizes runout and chatter when drilling steel, cast iron, aluminum, and similar materials at production feed rates. The TiN coating adds surface hardness and reduces friction, extending tool life compared to uncoated HSS in repetitive drilling cycles. Machinists, tool-and-die makers, and CNC operators are the typical end users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eScrew machine (stub) length for maximum rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003e0.1285 inch cutting diameter for precision hole sizing\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles a broad range of metals\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and extends tool life\u003c\/li\u003e\n\u003cli\u003eCompact overall length of approximately 1-15\/16 inches suits tight-clearance setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production tooling choice for any screw machine, turret lathe, or drill press accepting standard straight-shank stub-length drill bits in the 0.1285 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or CNC operators following standard toolroom practices. Secure the shank fully in the chuck or collet before operation and verify runout with a dial indicator on precision applications. Always power down and lock out the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to maximize coating life and chip evacuation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.1285 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\u003eOverall Length\u003c\/strong\u003e: 1-15\/16 inches\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: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Style\u003c\/strong\u003e: Screw Machine Length (Stub)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: YG-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: D4148130\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YG-1","offers":[{"title":"Default Title","offer_id":67913195880754,"sku":"D4148130","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acd1da08669892f7b09bebb7e334b439.jpg?v=1791243428","url":"https:\/\/voomisupply.com\/products\/yg-1-d4148130-screw-machine-drill-bit-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
