It features a 1.625-inch cutting diameter paired with a 3\/4-inch straight-cylindrical shank, allowing it to be chucked in standard drill presses and machine tool spindles that would not otherwise accept a full-size shank of equivalent diameter. The 118-degree split-point geometry is the standard included angle for high-speed steel bits used across a broad range of workpiece materials. The oxide finish provides a baseline level of corrosion resistance and heat dissipation during cutting operations. This bit is installed by machinists, maintenance technicians, and tool-and-die tradespeople.\u003c\/p\u003e\n\u003cp\u003eThe F.901.4128 is suited for production and maintenance drilling applications where a large-diameter hole is required but tooling or machine capacity limits shank size. With a 3-inch flute length and a maximum drilling depth of 3 inches, it handles through-holes and blind holes in moderate stock thickness. The 6-inch overall length fits standard drill press setups. General-purpose classification means it performs across a variety of ferrous and non-ferrous materials without requiring specialized cutting fluid or high-pressure coolant systems, though flood coolant is always recommended for extended production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.625-inch cutting diameter with a reduced 3\/4-inch straight-cylindrical shank for broader machine compatibility\u003c\/li\u003e\n  \u003cli\u003e118-degree point angle — the standard general-purpose geometry for HSS drill bits\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction maintains hardness and edge retention at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eOxide finish aids in corrosion resistance and reduces friction at the cutting interface\u003c\/li\u003e\n  \u003cli\u003e3-inch flute length supports a maximum drilling depth of 3 inches\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length fits conventional drill press and milling machine setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose reduced shank drill bit compatible with drill presses, milling machines, and similar machine tools equipped with a chuck or collet system that accepts a 3\/4-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and operated by machinists or maintenance tradespeople using a drill press, mill, or similar machine tool. Secure the 3\/4-inch shank fully in the chuck before operation and verify runout before cutting. Disengage and lock out all power to the machine before changing tooling.
