Built from high speed steel with an oxide coating, this bit measures 0.2660 inches in diameter and features a 130-degree point angle for aggressive, self-centering entry with reduced thrust. The parabolic flute geometry promotes fast chip evacuation, making it well-suited for deeper holes where chip packing is a concern. With an overall length of 4-9\/32 inches and a straight-cylindrical shank, it mounts directly in standard drill chucks and CNC tool holders. The web-thinned, tapered web design further reduces cutting force at the tip. This bit is a go-to choice for machinists, pipefitters, and maintenance technicians who need consistent, reliable performance across production and repair drilling tasks.\u003c\/p\u003e\u003cp\u003eThe 5059330 is appropriate for jobsite and shop use wherever a Letter H diameter hole is required. Common applications include clearance holes for fasteners, pilot drilling before reaming, and general-purpose hole-making in steel, cast iron, aluminum, and similar materials. The high-performance grade designation and parabolic flute make it suitable for both hand-held power drill and drill press use, as well as light-duty CNC drilling operations. The oxide finish provides a baseline level of lubricity and corrosion resistance during storage and initial cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter H diameter at 0.2660 inches for precise fractional and letter-size applications\u003c\/li\u003e\n\u003cli\u003e130-degree point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry accelerates chip evacuation in deeper holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers cutting resistance at the drill tip\u003c\/li\u003e\n\u003cli\u003eOxide coating provides lubricity and protects against surface corrosion\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard 3-jaw chucks and collet holders without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard jobber drill for any application requiring a Letter H diameter hole.

Always secure the workpiece and ensure the drill chuck is fully tightened before operation. Inspect the cutting edges and web for wear or chipping before each use, and replace the bit if the point is damaged to avoid workpiece damage or bit breakage. Follow applicable shop safety standards and use appropriate cutting fluid or lubricant for the material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2660 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-9\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-23\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2660 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 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: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\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 Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.2500 - 0.3000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: BS; DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER-TITEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5059330\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51735163011378,"sku":"5059330","price":32.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eee93b8c625185b1cb29c92e524b1f79.jpg?v=1788769973","url":"https:\/\/voomisupply.com\/products\/walter-titex-5059330-letter-h-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
