It carries a 0.1660-inch diameter (wire size 19), a 130-degree split point, and a parabolic flute geometry that promotes aggressive chip evacuation and reduced cutting force. The web-thinned, tapered web configuration further lowers entry resistance and improves centering accuracy. At 4.6875 inches overall length with a 3.0625-inch flute, this bit gives machinists and tool-room technicians the reach needed for deeper through-hole and stack-drilling applications without sacrificing rigidity.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for blind hole drilling, stack drilling, and through-hole drilling in aluminum, aluminum-silicon alloys, brass, bronze, copper alloys, stainless steel, and steel. The parallel shank (0.1660 inch diameter, 1.614 inches long) fits standard drill chucks and collet systems without adaptation. The Series A1522 designation places it within a high-performance product family conforming to DIN 340 geometry standards. Typical users include machine shop machinists, tool-and-die technicians, and maintenance mechanics working on precision assemblies or production fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e130-degree point angle for reduced thrust and improved self-centering on hard and layered materials\u003c\/li\u003e\n  \u003cli\u003eParabolic flute with 12xD flute-to-diameter ratio supports chip clearance in deep-hole applications\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting torque and entry force\u003c\/li\u003e\n  \u003cli\u003eCoated high-speed steel construction extends tool life across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with parallel shank for compatibility with standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 340 geometry standard for consistent dimensional performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a taper-length, parallel-shank drill bit conforming to DIN 340 standards; fits any standard drill chuck or collet system accepting a 0.1660-inch shank diameter. Rated for use in aluminum, aluminum-silicon, brass, bronze, copper alloy, stainless steel, and steel workpieces as stated by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with cutting-tool setup and safe machine operation. Secure the parallel shank fully in a properly sized drill chuck or collet before operation, and verify chuck runout is within acceptable tolerance for the application. Power down and lock out the spindle before changing or inspecting tooling. Do not exceed the maximum drilling depth of 2.795 inches without retracting to clear chips, particularly in blind-hole or stack-drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1660 inches (Wire Size 19)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.6875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.795 inches (71.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1660 inches (4.21 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.614 inches (41.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0387 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\u003eTool Material\u003c\/strong\u003e: High Speed Steel\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\u003eDiameter 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\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: 5155148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51730962612530,"sku":"5155148","price":33.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47a54e74f81d76d2abe586fdd2c46787_69cda8ad-9c87-4737-a8fb-a7b9cb45cfc1.jpg?v=1788725358","url":"https:\/\/voomisupply.com\/products\/walter-titex-5155148-taper-length-drill-bit-0-1660-in","provider":"Voomi Supply","version":"1.0","type":"link"}
