The 4.50 mm diameter bit features a 140-degree point angle optimized for self-centering entry and reduced thrust, paired with a multilayer TiAlN coating that extends tool life in abrasive and heat-intensive applications. With a 74.00 mm overall length and a tapered web configuration, this drill delivers rigidity and chip evacuation efficiency suited to CNC machining centers and production drilling fixtures. It is installed by machinists and tooling professionals in metal fabrication, job shop, and precision manufacturing settings.\u003c\/p\u003e\n\u003cp\u003eThis drill is intended for use in steel, stainless steel, cast iron, aluminum, and non-ferrous materials, covering a wide range of production drilling applications. The 5xD flute-to-diameter ratio and right-hand spiral flute geometry support consistent chip removal at moderate to high feed rates. Coolant-through capability allows internal coolant delivery directly to the cutting zone, making it well suited for deep-hole drilling cycles where heat buildup and chip packing are primary concerns. The straight cylindrical shank accommodates standard drill chucks and hydraulic toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for superior rigidity and wear resistance versus high-speed steel\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating for extended tool life in high-temperature cutting conditions\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust force and improves centering on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers cutting fluid directly to the drill tip for heat control\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration enhances chip flow and reduces walking on flat surfaces\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for consistent dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials.
