Built to DIN 1897 specification, this bit features a 130-degree conical point with U-geometry and a parabolic flute profile that promotes efficient chip evacuation and reduced heat buildup. At 0.136 inches (wire size 29) in diameter with an overall length of 2.0472 inches, it fits standard drill chucks via a straight-cylindrical shank. The M35 cobalt material grade provides elevated heat and wear resistance compared to standard HSS. Licensed HVAC techs, maintenance machinists, and fabrication shops installing or modifying metal assemblies will find this bit suited for precision short-hole work.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is optimized for use in cast iron, non-ferrous metals, stainless steel, and general steel applications. Its screw machine (stub) length geometry provides increased rigidity in drill presses, CNC machining centers, and hand-held power tools where shorter flute length reduces deflection. The 3xD flute-to-diameter ratio and tapered web configuration make it particularly effective in interrupted cuts and when drilling into work-hardening stainless grades. It is sold individually and is well-suited for production environments requiring consistent hole quality at the No. 29 wire gauge diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt construction rated for cast iron, stainless steel, non-ferrous metals, and alloy steel\u003c\/li\u003e\n  \u003cli\u003e130-degree conical point with U-geometry and web thinning for reduced thrust and faster penetration\u003c\/li\u003e\n  \u003cli\u003eParabolic 2-flute design promotes rapid chip evacuation and lowers cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body increases rigidity and minimizes deflection in short-hole drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 1897 and ISO standards with h8 diameter tolerance for consistent sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-purpose drill bit for applications requiring a No. 29 wire size (0.136 inch) diameter hole in ferrous and non-ferrous base materials.

Secure the workpiece firmly before drilling and confirm the shank is fully seated and clamped in the chuck or collet. Appropriate cutting fluid or coolant is recommended when drilling stainless steel or hardened alloys to extend tool life, even though this bit does not feature through-tool coolant. Inspect the cutting edges before each use and replace the bit if chipping or wear is visible to maintain hole tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.136 inches (Wire Size 29)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0472 inches (52 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.7874 inches (20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2598 inches (32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.5512 inches (14 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0317 inches (0.81 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.45 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\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: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Conical with U-geometry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M35 grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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: A1149XPL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897 \/ ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5337171\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51727081931058,"sku":"5337171","price":32.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f3206ec46db75e905bdab5426ee5e69.jpg?v=1788673006","url":"https:\/\/voomisupply.com\/products\/walter-titex-5337171-screw-machine-drill-bit-0-136-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
