Walter-titex 5155148 Taper Length Drill Bit 0.1660 in

Product Description

The WALTER-TITEX 5155148 is a taper length, high-speed steel twist drill bit designed for precision hole-making in a wide range of metallic workpiece materials. 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.

This 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.

Key Features

• 130-degree point angle for reduced thrust and improved self-centering on hard and layered materials
• Parabolic flute with 12xD flute-to-diameter ratio supports chip clearance in deep-hole applications
• Web-thinned tapered web reduces cutting torque and entry force
• Coated high-speed steel construction extends tool life across ferrous and non-ferrous materials
• Right-hand cut with parallel shank for compatibility with standard drill chucks and collets
• Conforms to DIN 340 geometry standard for consistent dimensional performance

Compatibility

Designed 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.

Installation Notes

Installation 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.
