Manufactured from high speed steel with a bright uncoated finish, this Series 552 bit features a parabolic flute geometry and a web-thinned, parallel web configuration that promotes efficient chip evacuation at shallow drilling depths. The 130-degree split point angle improves centering accuracy and reduces the thrust force needed at entry. At 3-5\/16 inches overall length with a 1-9\/16 inch flute length and a maximum drilling depth of 1.0360 inches, it fits tight-clearance applications where a jobber-length bit would be impractical. Right-hand cut with a straight-cylindrical shank for standard chuck compatibility.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for use in CNC machining centers, turret lathes, drill presses, and screw machine operations where stub rigidity reduces deflection and chatter. The parabolic flute design is particularly effective in aluminum and soft metals, where chip packing is a common failure mode. The 3xD flute-to-diameter ratio and web-thinned tip make this bit well matched to production environments requiring consistent hole quality in shallow-depth through-holes. It conforms to DIN 1897 standards, making it appropriate for shops specifying metric-standard tooling alongside inch-dimension workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e23\/64 inch (0.3594 inch) diameter with a tight tolerance of +0.000 to -0.022 mm for consistent fit\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry with web thinning for fast chip evacuation and reduced thrust\u003c\/li\u003e\n  \u003cli\u003e130-degree standard point angle for accurate self-centering entry\u003c\/li\u003e\n  \u003cli\u003eStub length construction increases rigidity and reduces deflection in short-reach applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — compatible with cutting fluid application for aluminum and non-ferrous work\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1897 specification for standardized tooling interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style stub-length drill bit for use in standard straight-shank drill chucks and collet systems accepting a 23\/64 inch shank.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Confirm chuck runout is within acceptable tolerance before beginning a production run, as excessive runout accelerates tool wear and degrades hole geometry. Apply appropriate cutting fluid or mist coolant when drilling aluminum to extend tool life, even though this bit does not feature internal coolant-through capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 23\/64 inch (0.3594 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.0360 inches (26.31 mm)\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\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 (Screw Machine Length)\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\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: 9005520091300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51735928865074,"sku":"9005520091300","price":49.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307b5f81382db76817d73168a256da90.jpg?v=1788774963","url":"https:\/\/voomisupply.com\/products\/guhring-9005520091300-drill-bit-23-64-in-hss-parabolic-stub","provider":"Voomi Supply","version":"1.0","type":"link"}
