Built from high speed steel with a bright uncoated finish, it carries a 0.0420 inch diameter corresponding to wire gauge size 58. The 130-degree drill point angle and parabolic flute geometry promote efficient chip evacuation and reduce cutting forces, making this bit well suited for blind hole, through hole, and stack drilling operations. The web-thinned, tapered web configuration minimizes entry resistance. This bit is typically installed by machinists, tool-and-die technicians, and maintenance professionals working with precision drilling equipment.\u003c\/p\u003e\n\u003cp\u003eThe 5154105 is rated for use in aluminum, aluminum silicon, brass, bronze, copper alloy, stainless steel, and steel. Its 12xD flute length to diameter ratio and overall length of 2-3\/8 inches give it added reach compared to a jobber-length bit, making it appropriate for applications requiring deeper hole penetration without switching to an extended series tool. The parallel shank fits standard drill chucks and collets without modification. Typical applications include production machining, maintenance repair, and fabrication environments where consistent hole quality in metalwork is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 58 diameter at 0.0420 inches with a tight tolerance of -0.00055 to 0.00000 inches\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design with web thinning for improved chip flow and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003e130-degree standard point angle suitable for most ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eTaper length body at 2-3\/8 inches overall with a 1-15\/32 inch flute length\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with parallel shank for compatibility with standard chucks and collets\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 340 standard; Series A1522 high performance grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in aluminum, aluminum silicon, brass, bronze, copper alloy, stainless steel, and steel workpieces.

Ensure the machine spindle and chuck are powered down and at a full stop before securing or removing the bit. Verify that the shank diameter seats fully and concentrically in the chuck or collet to prevent runout. Follow applicable shop safety standards and machine manufacturer guidelines for cutting fluid use and drill press or CNC operating parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0420 inches (Wire Size 58)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-15\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0420 inches (1.06 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.9050 inches (23.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.3780 inches (35.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0097 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.00055 to 0.00000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 12xD\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: Bright\/Uncoated\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, Web-Thinned\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eStandard\u003c\/strong\u003e: DIN 340\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1522\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: High Performance\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: 5154105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51730472567090,"sku":"5154105","price":230.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47a54e74f81d76d2abe586fdd2c46787_b8ed7363-3624-4567-bace-bdf5e130799b.jpg?v=1788718065","url":"https:\/\/voomisupply.com\/products\/walter-titex-5154105-taper-length-drill-bit-0-0420-in","provider":"Voomi Supply","version":"1.0","type":"link"}
