It measures 10.4 mm in diameter with a 144 mm overall length and 87 mm flute length. Manufactured from vanadium high speed steel with a WD1 coating, it delivers extended tool life and heat resistance under demanding cutting conditions. The 120-degree split point and S-thinned web reduce walking and lower thrust requirements, making it well suited for production drilling by machinists and maintenance technicians working in metal fabrication, repair, and industrial maintenance environments.\u003c\/p\u003e\u003cp\u003eThe 8656040 is intended for drilling blind holes, cross holes, and standard through-hole drilling applications in steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The straight-cylindrical shank with a 12 mm shank diameter seats securely in standard drill chucks and CNC tool holders. Regular spiral geometry promotes efficient chip evacuation in these materials. This bit is sized within the 10.00 to 12.50 mm diameter range and carries the OSG Series 1650 designation, which targets high-performance general-purpose drilling in both manual and automated setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVanadium high speed steel construction with WD1 coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003e120-degree drill point angle with S-thinned web reduces thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eSpiral flute geometry with regular helix promotes effective chip removal\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, two-flute design suited for steel, alloy steel, aluminum, and aluminum alloys\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and CNC holders without adapters\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance held to +0 to -0.027 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate workpieces.
