Built from high-speed steel with a bright, uncoated finish, it measures 0.1476 inches (3.75 mm) in diameter and carries a 130-degree point angle with a parabolic flute geometry. The web-thinned, parallel-web construction reduces thrust and improves chip evacuation. At 2.0472 inches in overall length with a 0.7874-inch flute length, this bit fits standard straight-cylindrical shank toolholders and is sized to the DIN 1897 stub-length standard. It is a right-hand cut tool suited for production drilling environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in screw machine operations, CNC drilling centers, and bench drill press setups where a compact stub-length tool provides rigidity and reduced deflection. Its parabolic flute profile and web-thinned point are optimized for aluminum as the primary workpiece material, though the high-speed steel construction is also serviceable in plastics and soft metals. A maximum drilling depth of 0.5660 inches makes it appropriate for short, through-hole or blind-hole applications in production runs. Machinists, tool-and-die professionals, and precision-shop technicians are the typical end users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.1476 inch (3.75 mm) diameter, DIN 1897 stub-length standard\u003c\/li\u003e\n  \u003cli\u003e130-degree split point angle reduces walking and entry burr\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast chip clearance in aluminum\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel-web construction lowers drilling thrust\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated high-speed steel finish, right-hand cut\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style stub-length drill bit conforming to DIN 1897, compatible with standard straight-cylindrical shank toolholders and drill chucks accepting a 3.75 mm shank diameter.

Secure the shank fully in the chuck or collet before operation and confirm runout is within acceptable tolerance. Do not exceed the maximum drilling depth of 0.5660 inches per pass without retracting to clear chips. Coolant-through is not supported on this tool; external flood or mist coolant is recommended when drilling aluminum at higher feed rates.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1476 inches (3.75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0472 inches (52.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.7874 inches (20.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.5660 inches (14.38 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 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  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 9005520037500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51755323818290,"sku":"9005520037500","price":18.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/285dd6ccceb7b563b154992045e17da4.jpg?v=1788953650","url":"https:\/\/voomisupply.com\/products\/guhring-9005520037500-screw-machine-drill-bit-0-1476-in","provider":"Voomi Supply","version":"1.0","type":"link"}
