Walter-titex 5061897 Taper Length Drill Bit 0.1654 in Hss

Product Description

The WALTER-TITEX 5061897 is a taper length twist drill bit designed for precision drilling in a wide range of metallic materials. Built from M-2 high speed steel with a coated finish, it measures 0.1654 inches (4.20 mm) in diameter and features a 130-degree split point with web thinning for fast, accurate starts without center-punching. The parabolic flute geometry promotes efficient chip evacuation, especially in deep-hole applications. At 4.6875 inches overall length with a flute-to-diameter ratio of 12xD, this bit is suited for taper-length drilling tasks that exceed the reach of standard jobber drills. Right-hand cut with a parallel shank and a DIN 340 standard profile.

This drill bit is intended for use in machine shop, fabrication, and industrial maintenance environments. It handles blind hole drilling, stack drilling, and through-hole drilling across a broad material range including aluminum, aluminum silicon alloys, brass, bronze, copper alloys, stainless steel, and steel. The A1522 series is designed for use in CNC machining centers, drill presses, and manual mills where consistent hole quality and extended tool life are required. No coolant-through capability; flood or mist coolant applied externally is standard practice for this configuration.

Key Features

• 0.1654 inch (4.20 mm) diameter with tight tolerance of -0.00071 to 0.00000 inches
• 130-degree UFL point with web thinning for reduced thrust and accurate entry
• Parabolic flute profile with tapered web for superior chip flow in deep cuts
• M-2 high speed steel construction with coated finish for extended wear resistance
• DIN 340 standard taper length, parallel shank, right-hand cut
• Rated for blind hole, through-hole, and stack drilling applications

Compatibility

Designed for use in standard parallel-shank drill chucks on CNC machining centers, drill presses, and milling machines. Compatible with aluminum, aluminum silicon, brass, bronze, copper alloy, stainless steel, and steel workpiece materials per Series A1522 specifications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with metal cutting operations. Secure the parallel shank firmly in a properly sized drill chuck before operation and confirm chuck runout is within acceptable tolerance to avoid premature bit wear. Power down and de-energize the machine spindle before changing tooling. Do not exceed the maximum drilling depth of 2.795 inches without retracting to clear chips, especially in blind-hole applications.
