Built from high speed steel with an oxide finish, each bit features a 135-degree split-point tip that reduces walking and allows drilling to start without a center punch. The straight shank design works with standard three-jaw drill chucks. This set meets NAS 907 specification and is sized on the inch measurement system, making it a reliable bench set for metal fabrication shops, maintenance departments, and trade contractors who need a complete letter-size range on hand.\u003c\/p\u003e\n\u003cp\u003eThe 45638 is engineered for metalworking and general multipurpose drilling applications. The full A-through-Z letter range covers intermediate hole sizes that fall between standard fractional increments, making this set especially useful when drilling to tap-drill sizes for machine screw threads. The 26 bits store in an included metal or plastic case, keeping each size indexed and accessible in a shop or service van environment. This is a high-performance series intended for production and maintenance use where consistent hole quality in steel, aluminum, and similar materials is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFull letter series A through Z — 26 jobber length drills in one set\u003c\/li\u003e\n  \u003cli\u003e135-degree split-point geometry reduces tip walking and cutting thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide finish for wear resistance\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 specification for consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction; no coolant-through requirement\u003c\/li\u003e\n  \u003cli\u003eIncludes metal or plastic indexed storage case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard three-jaw keyed or keyless drill chucks on benchtop drill presses, hand drills, and milling machines.

Ensure the chuck is fully tightened and the workpiece is securely clamped before drilling. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and maintain hole quality. Inspect each bit for signs of wear or damage before use and replace any bit that shows chipping or excessive dulling at the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Type\u003c\/strong\u003e: Jobber Length Drill Bits\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 26\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: Letter A through Z\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: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Jobber Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150ASP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStorage Case Material\u003c\/strong\u003e: Metal or Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Metalworking, Multipurpose Drilling\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: 45638\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51734729916722,"sku":"45638","price":251.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22d354541d8ed42c1753f272e1735289.jpg?v=1788766243","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-45638-drill-bit-set-26-pc-letter-a-z-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
