It carries a 0.1520-inch diameter, a 130-degree split point angle, and a parabolic flute geometry that promotes efficient chip evacuation and reduces heat buildup. The coated finish extends tool life across high-cycle applications. At 4-11\/16 inches overall length with a 3-1\/16-inch flute length, this bit handles deeper reach requirements that standard jobber-length drills cannot accommodate. It is sized to wire gauge #24 and suits machine shop, MRO, and production drilling operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for blind hole drilling, through-hole drilling, and stack drilling across a broad range of materials including aluminum, aluminum silicon alloys, brass, bronze, copper alloy, stainless steel, and steel. The parallel shank and web-thinned tapered web design make it compatible with standard drill chucks and CNC machining centers. The parabolic flute profile and 12xD flute-to-diameter ratio allow it to reach a maximum drilling depth of 2.7950 inches (71.00 mm) without sacrificing chip clearance or cutting performance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1520-inch diameter, wire gauge #24 sizing for precise hole tolerances\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with web-thinned, tapered web for reduced thrust and clean entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute design promotes rapid chip evacuation in deep-hole applications\u003c\/li\u003e\n\u003cli\u003eCoated HSS construction rated for high-performance cutting in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eTaper length body at 4-11\/16 inches overall provides extended reach versus jobber-length equivalents\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 340 standard; Series A1522\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe 5155142 is designed for use with standard parallel-shank drill chucks and CNC spindles accepting a 0.1520-inch (3.86 mm) shank diameter.

Ensure the spindle and workpiece are properly secured before operation. Set appropriate feed and speed parameters for the target material to avoid work hardening, especially when drilling stainless steel. Inspect the cutting edge and coating before each use and replace the bit when wear affects hole tolerance or surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1520 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Gauge Size\u003c\/strong\u003e: #24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1520 inches (3.86 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.6140 inches (41.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.7950 inches (71.00 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\u003eDrill Point Length\u003c\/strong\u003e: 0.0354 inches\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003c\/strong\u003e: Coated\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.00071 to 0.00000 inches\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\u003eDrill Bit Grade\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\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: 5155142\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51737576898866,"sku":"5155142","price":32.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47a54e74f81d76d2abe586fdd2c46787_471f35d3-7844-4cef-8c25-13b3717b3c04.jpg?v=1788790724","url":"https:\/\/voomisupply.com\/products\/walter-titex-5155142-taper-length-drill-bit-0-152-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
