Built from high speed steel with a bright uncoated finish, this bit features a 31\/64 inch diameter, a 130-degree drill point angle, and a parabolic flute geometry that improves chip evacuation and reduces heat buildup during cutting. The overall length is 5-15\/16 inches with a flute length of 3-31\/32 inches. It is web-thinned at the tip to reduce entry resistance and cutting force. This bit is used by machinists, tool and die technicians, and maintenance professionals who require consistent hole tolerances in production or repair work.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in aluminum, non-ferrous metals, and general steel applications per its primary workpiece material designations. The parabolic flute design handles deeper passes with fewer pecking cycles, making it well suited for CNC drilling centers, drill presses, and hand-held power tools in shop or field settings. The straight-cylindrical shank accepts standard drill chucks without modification. Conforming to DIN 338, this bit meets the dimensional and performance standards expected in professional metalworking environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e31\/64 inch diameter with a diameter tolerance of -0.027 to 0.000 mm for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e130-degree split point angle reduces walking and improves entry accuracy\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast chip removal and reduced heat buildup\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tip lowers cutting force on entry\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 dimensional standards for jobber length drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 338 jobber length drill bit compatible with standard straight-shank drill chucks on CNC machining centers, drill presses, and portable power tools used in aluminum, non-ferrous, and general steel drilling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools.
