Walter-titex 5154083 Taper Length Drill Bit 0.2090 in

Product Description

The WALTER-TITEX 5154083 is a taper length twist drill bit designed for high-performance drilling in a wide range of metals. Built from High Speed Steel (HSS) with a coated finish, this bit is engineered for productivity in blind hole, stack drilling, and through hole applications. The parabolic flute geometry promotes efficient chip evacuation, and the web-thinned, tapered web configuration reduces cutting forces at the tip. At a 130-degree point angle, the bit delivers aggressive, self-centering entry. The 5154083 is a wire gauge size 4 drill, measuring 0.2090 inches in diameter, with an overall length of 5.469 inches and a flute length of 3.594 inches. Licensed machinists, tool and die makers, and precision metalworkers are the primary installers of this tool.

The 5154083 is suited for production and maintenance drilling in both residential shop environments and commercial manufacturing settings. It is rated for use in aluminum, aluminum silicon alloys, brass, bronze, copper alloy, stainless steel, and steel. The Series A1522 designation identifies it within the WALTER-TITEX taper length line, which is built to DIN 340 dimensional standards. The parallel shank accepts standard drill chucks without adapters, making it compatible with benchtop drill presses, CNC machining centers, and handheld power tools equipped with a keyed or keyless chuck sized to the 0.2090-inch shank diameter.

Key Features

• Parabolic flute geometry promotes fast, efficient chip evacuation in deep-hole applications
• Web-thinned, tapered web reduces thrust force and improves point penetration
• 130-degree point angle provides aggressive entry and works across a broad range of metal types
• HSS construction with coated finish extends tool life in abrasive and heat-generating materials
• DIN 340 taper length body provides extra reach compared to jobber-length equivalents
• No coolant-through requirement simplifies setup in standard drilling operations

Compatibility

Designed to DIN 340 taper length standards and compatible with applications in aluminum, aluminum silicon, brass, bronze, copper alloy, stainless steel, and steel. Fits any standard drill chuck accepting a 0.2090-inch parallel shank. Suitable for blind hole, stack drilling, and through hole drilling operations.

Installation Notes

This drill bit is installed by machinists, toolroom technicians, and maintenance mechanics using standard drill chucks or collet systems. Secure the parallel shank firmly in the chuck before operation and verify concentricity to minimize runout. Always power down and de-energize the machine spindle before changing tooling. Follow the machine manufacturer and applicable shop safety guidelines for speeds and feeds when drilling stainless steel or copper alloys, as these materials generate significant heat.
