Built from High Speed Steel (HSS) with a coated finish, this bit is engineered for productivity in blind hole, stack drilling, and through hole applications. The parabolic flute geometry promotes efficient chip evacuation, and the web-thinned, tapered web configuration reduces cutting forces at the tip. At a 130-degree point angle, the bit delivers aggressive, self-centering entry. The 5154083 is a wire gauge size 4 drill, measuring 0.2090 inches in diameter, with an overall length of 5.469 inches and a flute length of 3.594 inches. Licensed machinists, tool and die makers, and precision metalworkers are the primary installers of this tool.\u003c\/p\u003e\n\u003cp\u003eThe 5154083 is suited for production and maintenance drilling in both residential shop environments and commercial manufacturing settings. It is rated for use in aluminum, aluminum silicon alloys, brass, bronze, copper alloy, stainless steel, and steel. The Series A1522 designation identifies it within the WALTER-TITEX taper length line, which is built to DIN 340 dimensional standards. The parallel shank accepts standard drill chucks without adapters, making it compatible with benchtop drill presses, CNC machining centers, and handheld power tools equipped with a keyed or keyless chuck sized to the 0.2090-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast, efficient chip evacuation in deep-hole applications\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces thrust force and improves point penetration\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle provides aggressive entry and works across a broad range of metal types\u003c\/li\u003e\n  \u003cli\u003eHSS construction with coated finish extends tool life in abrasive and heat-generating materials\u003c\/li\u003e\n  \u003cli\u003eDIN 340 taper length body provides extra reach compared to jobber-length equivalents\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies setup in standard drilling operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to DIN 340 taper length standards and compatible with applications in aluminum, aluminum silicon, brass, bronze, copper alloy, stainless steel, and steel.

Secure the parallel shank firmly in the chuck before operation and verify concentricity to minimize runout. Always power down and de-energize the machine spindle before changing tooling. Follow the machine manufacturer and applicable shop safety guidelines for speeds and feeds when drilling stainless steel or copper alloys, as these materials generate significant heat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2090 inches (Wire Size 4)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.469 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.594 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.228 inches (82.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2090 inches (5.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.889 inches (48.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0487 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 Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 12xD\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: Parallel (non-threaded)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.00071 to 0.00000 inches (-0.018 to 0.000 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Aluminum Silicon, Brass, Bronze, Copper Alloy, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Stack Drilling, Through Hole Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1522\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 340\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5154083\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51730953929010,"sku":"5154083","price":36.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47a54e74f81d76d2abe586fdd2c46787_f5a49fb8-ba17-4b81-a871-89d988a8fc58.jpg?v=1788725229","url":"https:\/\/voomisupply.com\/products\/walter-titex-5154083-taper-length-drill-bit-0-2090-in","provider":"Voomi Supply","version":"1.0","type":"link"}
