Built to DIN 6539 standards, this bit features a 3-flute spiral configuration with a web-thinned, tapered web for improved chip evacuation and self-centering entry. The submicron carbide grade delivers the hardness and heat resistance needed for consistent performance in demanding production drilling applications. The bright, uncoated finish is suitable for a range of workpiece materials. Overall length is 2.75 inches with a straight-cylindrical shank of 0.2500 inches diameter.\u003c\/p\u003e\u003cp\u003eThis Series 1452 drill bit is suited for precision jobber-length drilling in machine shop, manufacturing, and maintenance environments. Its self-centering point geometry reduces the need for a center punch or pilot hole on flat and prepared surfaces. The right-hand cut with regular spiral flute geometry handles a broad range of materials. Maximum drilling depth is 1.279 inches, making it appropriate for through-holes and shallow blind holes in production setups where accuracy and repeatability matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in submicron grade for extended tool life in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003e150-degree point angle with self-centering geometry reduces walking and pilot hole requirements\u003c\/li\u003e\n\u003cli\u003e3-flute spiral design improves chip removal and supports higher feed rates compared to standard 2-flute bits\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers thrust force at entry\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of cutting fluids and dry applications\u003c\/li\u003e\n\u003cli\u003eManufactured to DIN 6539 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit jobber-length carbide drill bit for use in CNC machining centers, drill presses, and hand-held drilling equipment accepting a 1\/4-inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before inserting or removing tooling. Secure the straight-cylindrical shank firmly in a collet or drill chuck rated for the shank diameter to prevent runout. Solid carbide tooling is brittle and should not be used in setups with excessive vibration or side-loading, as this can cause fracture.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 1\/4 inch (Letter E)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 150 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Finish \/ Coating\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.6535 inches (42.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches (69.85 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.279 inches (32.48 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard, Self-Centering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1452\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6539\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.015 to 0.000 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9014520063500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732758724914,"sku":"9014520063500","price":151.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/134cba6dcaeccadcb695557ad00ff840.jpg?v=1788746388","url":"https:\/\/voomisupply.com\/products\/guhring-9014520063500-carbide-jobber-drill-bit-letter-e","provider":"Voomi Supply","version":"1.0","type":"link"}
