Walter-titex 7377819 Taper Length Drill Bit 3 Mm Carbide

Product Description

The WALTER-TITEX 7377819 is a solid carbide taper length drill bit engineered for high-performance drilling in demanding industrial and trade applications. Built to DIN 6537 K standards, this bit features a 140-degree split point, a TiSiAlCrN coating, and through-coolant capability for extended tool life and precise hole quality. At 3 mm in diameter with a 6 mm parallel shank and an 8xD flute-to-diameter ratio, it is sized for high-accuracy work where chip evacuation and thermal control are critical. Licensed machinists, tool and die specialists, and industrial maintenance technicians are the primary installers.

This drill bit is suited for a range of hole types including blind holes, cross holes, inclined holes, stack drilling, and through hole drilling. It performs in production machining environments where consistent accuracy and surface finish are required across multiple workpiece materials. The 34 mm flute length accommodates a maximum drilling depth of 28 mm, making it appropriate for moderate-depth bores in components requiring tight dimensional tolerances. It is classified under material grade WJ30ET, indicating suitability for a broad range of workpiece materials typical in precision machining operations.

Key Features

• Solid carbide construction rated to material grade WJ30ET for high wear resistance
• TiSiAlCrN coating reduces heat buildup and extends cutting edge life
• Through-coolant design supports chip flushing and thermal management at depth
• 140-degree drill point angle for self-centering entry and reduced thrust force
• 8xD flute-to-diameter ratio delivers effective chip evacuation in deep-hole applications
• Right-hand spiral flute geometry conforms to DIN 6537 K standard

Compatibility

Designed as an OEM-style tooling component for use in CNC machining centers, drill presses, and precision boring equipment that accept a 6 mm parallel shank with no threaded shank interface.

Installation Notes

Installation should be performed by qualified machinists or tooling technicians familiar with precision drill bit setup. Ensure the machine spindle and tool holder are de-energized and locked out before changing tooling. The parallel shank requires a compatible collet or chuck rated for the 6 mm shank diameter. Through-coolant connections should be verified and purged before initiating a drilling cycle to prevent thermal damage to the cutting edge.
