It carries a wire gauge size 52, equal to 0.0635 inches in diameter, and is manufactured from high speed steel with an oxide coating that helps reduce friction and extend service life in production environments. The 135-degree split point geometry allows the bit to start on contact without a center punch, reducing walking on smooth or hard surfaces. At 1-7\/8 inches overall length, this is a compact, standard jobber-length tool suited to hand drills, drill presses, and CNC equipment. Licensed trade technicians and machining professionals install and use this bit in metal fabrication, maintenance, and assembly operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for drilling cast iron, stainless steel, and carbon steel. The regular spiral flute and tapered web configuration support efficient chip evacuation in through-hole and blind-hole applications. The straight-cylindrical shank at 0.0635 inches in diameter seats securely in standard keyless or keyed chucks. It conforms to NAS 907 Type B standards, making it appropriate for aerospace-adjacent and heavy-duty industrial work where dimensional consistency and performance are required. It is sold as a single bit with a minimum order quantity of 12 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 52 (0.0635 inches) with tight diameter tolerance of -0.0005 to 0.0000 inches for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust force and eliminates the need for center-punching on hard materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide finish for reduced friction and improved tool life\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design promotes effective chip evacuation in spiral flute channel\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks across corded, cordless, and bench drill equipment\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type B specification for heavy-duty, high-performance drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with cast iron, stainless steel, and carbon steel workpieces.

Secure the straight shank firmly in the chuck before operation and verify chuck runout to maintain hole accuracy at this small diameter. Always wear appropriate eye protection when drilling ferrous metals and use cutting fluid on stainless steel to reduce heat buildup. Consult applicable shop safety standards and equipment manufacturer guidelines for recommended spindle speeds at this bit diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 52\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0635 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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\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\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0635 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150ASP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0019 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 45722\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51748652843314,"sku":"45722","price":31.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/782460eef0061e5342807dea23a26913_0b481323-5f34-4910-8509-89304bc71088.jpg?v=1788896226","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-45722-jobber-drill-bit-size-52-hss-135-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
