It is sized to wire gauge number 29, which equals 0.1360 inches in decimal. The 130-degree split point and parabolic flute design work together to reduce walking at entry and clear chips efficiently during deeper drilling operations. A web-thinned, parallel web construction reduces thrust requirements and helps maintain accuracy through the cut. This bit is suited to production and job-shop environments where taper length reach and precise hole sizing are required in metal fabrication and mechanical assembly work.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for right-hand cutting in materials including aluminum alloy, cast iron, and steel. The taper length format provides extended reach beyond a jobber-length bit, making it useful in applications where standard-length drills cannot access the workpoint. With a flute-to-diameter ratio of 10xD and a maximum drilling depth of 2.67 inches, it handles through-holes and deeper blind holes in structural components, fixtures, and machined parts. It is typically used by machinists, tool-and-die tradespeople, and maintenance mechanics running drill presses or CNC equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size number 29 (0.1360 inches decimal) for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with web thinning reduces entry thrust and walking\u003c\/li\u003e\n\u003cli\u003eParabolic flute profile promotes fast chip evacuation in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles aluminum alloy, cast iron, and steel\u003c\/li\u003e\n\u003cli\u003eTaper length body with 10xD flute-to-diameter ratio for extended reach applications\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 340 specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style taper length drill bit replacement for applications requiring wire gauge number 29 sizing in standard drill chucks accepting a 0.1358-inch cylindrical shank.

Secure the workpiece firmly before drilling and verify chuck grip on the cylindrical shank before applying feed pressure. Always wear appropriate eye protection and follow shop safety protocols when drilling metal. Do not exceed the rated maximum drilling depth of 2.67 inches per pass without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 535\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: Number 29\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1360 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.406 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.67 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1358 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length x Diameter Ratio\u003c\/strong\u003e: 10xD\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum Alloy, Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreaded Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9005350034500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727422030130,"sku":"9005350034500","price":30.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1607b93ea67d2ff5807f8550500cb261.jpg?v=1788677735","url":"https:\/\/voomisupply.com\/products\/guhring-9005350034500-taper-length-drill-bit-29-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
