Walter-titex 5154110 Taper Length Drill Bit 0.1990 in

Product Description

The WALTER-TITEX 5154110 is a taper length twist drill bit designed for precision hole-making in a wide range of metallic materials. Built from high-speed steel with a coated finish, this bit features a parabolic flute geometry and a web-thinned, tapered web configuration that improves chip evacuation and reduces thrust in demanding applications. The 130-degree split point promotes accurate positioning and minimizes walking on entry. At 0.1990 inches in diameter with an overall length of 5.1875 inches, it handles blind hole, through hole, and stack drilling operations. It is used by machinists, tool and die technicians, and metalworking professionals in production and maintenance environments.

The 5154110 is suited for drilling aluminum, aluminum silicon alloys, brass, bronze, copper alloys, stainless steel, and carbon and alloy steels. The 12xD flute-to-diameter ratio and 3.4375-inch flute length support deeper hole applications where standard-length bits fall short. Stack drilling setups and through-hole applications in sheet and plate stock are common use cases. This bit conforms to DIN 340 standards and is cataloged as a high-performance grade tool, making it appropriate for CNC machining centers and manual drill press operations alike.

Key Features

• Parabolic flute geometry promotes fast chip evacuation in deep hole drilling
• Web-thinned tapered web reduces entry thrust and improves point strength
• 130-degree standard point angle suits a broad range of metallic workpiece materials
• Coated high-speed steel construction extends tool life versus uncoated HSS
• Parallel shank fits standard drill chucks without adapters
• Conforms to DIN 340 taper length standard for consistent dimensional interchangeability

Compatibility

Designed as a DIN 340 taper length replacement or new-install drill bit for use in standard parallel-shank drill chucks on CNC machining centers, drill presses, and hand drill equipment. Compatible material applications include aluminum, aluminum silicon, brass, bronze, copper alloy, stainless steel, and steel.

Installation Notes

Installation is performed by machinists or tooling technicians. Ensure the drill chuck is clean and free of debris before seating the parallel shank, and verify runout with a dial indicator on precision setups. Secure workpieces firmly before drilling to prevent movement, especially during stack drilling operations. Follow applicable shop safety protocols and machine-specific operating procedures when setting spindle speed and feed rate for the workpiece material.
