Built from high speed steel with a bright, uncoated finish, this Series 552 bit features a parabolic flute geometry and a web-thinned parallel web that promotes efficient chip evacuation and reduced thrust in short-reach applications. The 130-degree split point angle supports accurate starting without a center punch. At 9\/32 inches (0.2812 inches) in diameter with a straight-cylindrical shank, it is sized for use in drill presses, CNC machining centers, and hand-held power tools. Machinists and tool-and-die professionals install this style of bit for repetitive production drilling where a stubby, rigid tool is preferred over a jobber-length bit.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for primary use in aluminum and is well suited to non-ferrous metals and softer workpiece materials common in production screw machine and light machining operations. The parabolic flute profile moves chips up and out of the hole quickly, which reduces heat buildup and extends tool life during high-cycle drilling. The stub-length body provides added rigidity compared to jobber-length drills, making it a practical choice when drill press quill travel is limited or when chatter is a concern in tight fixture setups. The straight-cylindrical shank fits standard drill chucks without an adapter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/32 inches (0.2812 inches) diameter, also cataloged as Letter K drill size\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in repetitive production drilling\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast chip evacuation and reduced cutting force\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with web-thinned parallel web for accurate entry\u003c\/li\u003e\n  \u003cli\u003eStub length body (2-29\/32 inches overall) provides rigidity in tight setups\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for aluminum and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 1897 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-service drill bit for standard 3-jaw drill chucks accepting straight-cylindrical shanks.

Secure the straight-cylindrical shank fully in the chuck jaws and verify runout before drilling. Disengage power and lock the spindle before changing or inspecting bits. Do not use this stub-length bit as a substitute for a jobber or aircraft-extension drill where reach depth exceeds the rated maximum drilling depth of 0.917 inches.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2812 inches (9\/32 inches, Letter K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-29\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-11\/32 inches (1.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.917 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, web-thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 552\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9005520071400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51737205145906,"sku":"9005520071400","price":34.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52f5d54cdfedeb55641c831d8951db60.jpg?v=1788785562","url":"https:\/\/voomisupply.com\/products\/guhring-9005520071400-screw-machine-drill-bit-9-32-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
