Built to DIN 1897 specification, this two-flute, right-hand spiral drill features a 118-degree four-facet split point with web thinning for accurate self-starting entry and reduced thrust. The straight cylindrical shank measures 9.50 mm (0.374 inches) in diameter and accepts standard drill chucks. At an overall length of 84.00 mm (3.31 inches), the stub format delivers rigidity and reduced deflection in short-hole drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is sized for work in aluminum and other non-ferrous or soft ferrous materials where a rigid, short-reach tool is preferred over a jobber-length bit. The stub format makes it well suited for CNC machining centers, drill presses, and hand-held power tools where chatter and bit flex are concerns. The Series 5520 cobalt construction provides heat resistance during interrupted cuts and in materials with moderate abrasiveness. Maximum drilling depth is 1.014 inches (25.75 mm), with a 3xD flute-to-diameter ratio that aids chip evacuation in shallow-to-medium depth holes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for elevated heat and wear resistance compared to standard HSS\u003c\/li\u003e\n  \u003cli\u003e118-degree four-facet split point with web thinning for self-centering entry and lower thrust force\u003c\/li\u003e\n  \u003cli\u003eStub (screw machine) length body for increased rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute geometry promotes chip clearing in through and blind holes\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 1897 specification for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification stub drill for use in standard drill chucks and collet systems accepting a 9.50 mm straight cylindrical shank.
