Built from high-speed steel with a bright uncoated finish, it features a 135-degree split-point tip that self-centers on contact and reduces the need for a center punch. The two-flute spiral design with a regular spiral type and web-thinned, tapered web configuration promotes efficient chip evacuation and reduces cutting resistance. At 4.625 inches overall length with a 3.3125-inch flute length, this is a standard jobber-length format suited for hand drills, drill presses, and CNC applications. Conforms to NAS 907 Type B specification.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated heavy duty and is well-suited for drilling aluminum as its primary workpiece material, though the HSS construction and NAS 907 Type B compliance make it applicable across a range of soft metals and general shop materials. The straight-cylindrical shank with a 0.3230-inch diameter fits standard three-jaw drill chucks without an adapter. It is a solid choice for HVAC techs, plumbers, electricians, and sheet metal workers needing a reliable Letter P drill for tapping pilot holes, conduit work, or bracket fabrication.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter P size at 0.3230 inches with a tight diameter tolerance of -0.0010 to 0.0000 inches for precision drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split-point tip self-centers and minimizes walking on flat surfaces\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces thrust force and improves chip flow\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction rated for heavy-duty use per NAS 907 Type B\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish allows visual wear inspection during service life\u003c\/li\u003e\n\u003cli\u003eStandard straight-cylindrical shank fits common drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber-length drill bit compatible with standard three-jaw drill chucks accepting a 0.3230-inch straight-cylindrical shank, suitable for drill presses, hand drills, and CNC spindles configured for jobber-length tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove this bit with the drill or press fully powered down and the chuck key removed from the immediate work area. Secure the shank fully into the chuck jaws and tighten evenly to prevent runout. When drilling metals, use an appropriate cutting fluid to extend tool life and maintain hole quality.
