Built from high speed steel with a coated finish, it features a 1-25\/64 inch cutting diameter paired with a 1\/2 inch Weldon shank, allowing it to run in standard 1\/2 inch chuck equipment without requiring a larger spindle. The 118-degree standard point angle provides a versatile, self-centering entry across a broad range of workpiece materials. This bit is suited for trade professionals who need a reliable general-purpose drill in a reduced shank configuration for portable or handheld drilling setups.\u003c\/p\u003e\n\u003cp\u003eThe 52489 is built for general-purpose portable drilling across wood, alloy steel, carbon steel, and cast iron workpieces. The Weldon shank with three flats prevents slipping in set-screw style toolholders, making it well suited for field work and production environments where consistent drive engagement matters. The right-hand spiral flute geometry clears chips efficiently during through-hole and blind-hole drilling operations in both stationary and handheld equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-25\/64 inch cutting diameter with a 1\/2 inch reduced Weldon shank for use in standard 1\/2 inch chuck equipment\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry on steel, cast iron, and wood\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides heat and wear resistance during extended drilling cycles\u003c\/li\u003e\n  \u003cli\u003eCoated finish helps reduce friction and extend cutting life\u003c\/li\u003e\n  \u003cli\u003eThree-flat Weldon shank prevents rotational slippage in set-screw toolholders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose reduced shank drill bit compatible with 1\/2 inch Weldon-style toolholders and standard 1\/2 inch chuck equipment used in portable drilling applications on wood, alloy steel, carbon steel, and cast iron workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit is typically performed by machinists, maintenance technicians, or skilled tradespeople using portable or stationary drilling equipment. Secure the Weldon shank fully in the toolholder and tighten all set screws against the flats before operation to prevent shank pullout. Ensure the drill press or handheld tool is powered down and isolated before changing bits. Do not use this bit without adequate chip clearance or at feed rates that cause excessive heat buildup, as this can reduce cutting edge life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1-25\/64 inches (1.3906 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Portable Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron, Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Required\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 190F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 52489\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51727383789874,"sku":"52489","price":242.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a09e90d707075c064bf08301be23d2c_906ee65e-a93e-4a5c-87c1-1523925d12b2.jpg?v=1788677085","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-52489-reduced-shank-drill-bit-1-25-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
