Walter-titex 7577855 Micro Drill Bit 0.0591 in Solid Carbide

Product Description

The WALTER-TITEX 7577855 is a solid carbide micro drill bit designed for precision drilling in demanding industrial and machining applications. Measuring 0.0591 inches in diameter with a 140-degree drill point angle, it delivers clean entry geometry suited for hard and difficult-to-machine materials. The AlCrN coating provides thermal and oxidation resistance, extending tool life in high-speed cutting environments. At 2.0870 inches overall length with a straight-cylindrical shank, this bit is built for CNC machining centers and precision drill presses where runout and repeatability are critical. It is installed and used by machinists and tooling professionals.

This micro drill bit is suited for blind hole, stack drilling, and through hole drilling operations across a range of workpiece materials. Primary materials include cast iron, non-ferrous metal, stainless steel, and steel. Secondary workpiece materials include cobalt, glass, graphite, iron alloy, nickel, titanium, and titanium alloy. The 5xD flute-by-diameter ratio supports deeper cuts relative to diameter, and coolant-through capability makes it compatible with internal coolant delivery systems common in production machining environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard material drilling
• AlCrN coating for high-temperature oxidation resistance and extended tool life
• 140-degree drill point angle reduces thrust force and improves chip control
• Coolant-through design supports internal coolant delivery for deep-hole and high-feed applications
• Right-hand cutting direction with straight-cylindrical shank for standard collet and chuck compatibility
• Conforms to DIN 6535 HA shank standard for consistent toolholder fitment

Compatibility

Designed for use in CNC machining centers and precision drill presses equipped with straight-cylindrical toolholders conforming to DIN 6535 HA. Compatible with workpiece materials including cast iron, non-ferrous metal, stainless steel, steel, cobalt, glass, graphite, iron alloy, nickel, titanium, and titanium alloy. Part of the WALTER-TITEX Series DB133-05-A1.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine powered down and all stored energy released before handling. Use a properly sized collet or drill chuck rated for the 0.1180-inch shank diameter to ensure concentricity and minimize runout. Verify coolant-through connections are secure before initiating cuts, and confirm spindle direction is set to right-hand rotation before operation.
