Walter-titex 5155145 Taper Length Drill Bit 0.159 in Hss

Product Description

The WALTER-TITEX 5155145 is a taper length twist drill bit designed for high-performance drilling across a broad range of metals. Built from high speed steel (HSS) with a coated finish, this bit features a parabolic flute geometry and a web-thinned, tapered web configuration that promotes efficient chip evacuation and reduces thrust in demanding applications. The 130-degree split point provides accurate self-centering entry without a center punch. At 0.1590 inches in diameter with a 4-11/16-inch overall length and a 3-1/16-inch flute length, it handles deep-hole work within its 12xD flute-to-diameter ratio. Licensed trades and machining professionals turn to this bit for blind hole, stack, and through-hole drilling operations.

This drill bit is suited for use in ferrous and non-ferrous metal applications, including aluminum, aluminum silicon alloys, brass, bronze, copper alloys, stainless steel, and steel. The parallel shank and 0.1590-inch shank diameter make it compatible with standard drill chucks across benchtop drill presses, CNC machining centers, and hand-held power tools where tight-tolerance hole sizing is required. The Series A1522 designation places it within a family built to DIN 340 taper length standards, common in precision metalworking and fabrication environments.

Key Features

• High speed steel construction with coated finish for extended tool life in metal applications
• Parabolic flute geometry promotes fast chip removal and reduces heat buildup
• 130-degree standard point with web thinning for accurate entry and reduced walking
• Right-hand cut with parallel shank for use in standard drill chucks
• Maximum drilling depth of 2.7950 inches supports deep hole work in a single pass
• Conforms to DIN 340 taper length standard for consistent dimensional performance

Compatibility

Designed as a DIN 340 taper length replacement or production-use drill bit for applications in aluminum, aluminum silicon, brass, bronze, copper alloy, stainless steel, and steel. Suitable for blind hole, stack drilling, and through-hole drilling operations across compatible drill chucks accepting a 0.1590-inch parallel shank.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Secure the parallel shank fully in the chuck and verify runout before drilling. Always wear appropriate eye protection and ensure the workpiece is firmly clamped before initiating a cut. Follow machine manufacturer guidelines for spindle speed and feed rate appropriate to the workpiece material.
