Built from high speed steel with a titanium nitride (TiN) coating, the bit holds a 25\/64 inch diameter and features a 118-degree standard point angle with a web-thinned tip to reduce thrust and improve centering. Overall length is 5.125 inches with a 3.75 inch flute length. The straight cylindrical shank fits standard three-jaw chucks on both hand-held drills and drill presses. This is a Series 150T bit rated for general-purpose use by machinists, pipefitters, electricians, and HVAC technicians who drill ferrous and non-ferrous stock daily.\u003c\/p\u003e\n\u003cp\u003eThe 70225 is suited for drilling cast iron and steel in both shop and field settings. Its regular spiral flute geometry and right-hand cut make it compatible with conventional drill presses, magnetic base drills, and handheld corded or cordless drills. The TiN coating extends surface hardness and reduces friction, making it a practical choice when drilling through structural steel, mechanical components, brackets, and pipe flanges. Single-piece packaging makes it easy to stock individually or as part of a jobsite kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e25\/64 inch diameter with a tight tolerance of -0.0010 to 0.0000 inches for accurate hole sizing\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and reduces heat buildup during cutting\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tip lowers entry thrust and improves bit self-centering\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, two-flute design promotes efficient chip evacuation in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 dimensional standard for jobber-length drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in steel and cast iron workpieces.

Secure the workpiece before drilling and ensure the chuck is fully tightened on the shank before applying power. Use cutting fluid or coolant when drilling through thick steel stock to manage heat, even though this bit does not support through-coolant delivery. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed to maintain hole-size accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 25\/64 inch (0.3906 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 25\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.375 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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\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: 150T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 pounds\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: 70225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51734439035186,"sku":"70225","price":27.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f323cbd8ec8fbcb052d0d44472e0a6e.jpg?v=1788763055","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-70225-jobber-drill-bit-25-64-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
