Walter-titex 7577865 Micro Drill Bit 0.0768 in Solid Carbide

Product Description

The WALTER-TITEX 7577865 is a solid carbide micro drill bit designed for precision drilling in demanding industrial applications. The bit measures 0.0768 inches in diameter with a 140-degree drill point angle and a total overall length of 2.2440 inches. An AlCrN coating provides thermal resistance and extended tool life during high-speed operations. The right-hand cutting direction and straight-cylindrical shank conform to DIN 6535 HA standards. This bit is built for machinists and tooling professionals who require tight-tolerance, repeatable results in small-diameter drilling operations.

This micro drill bit is suited for blind hole drilling, stack drilling, and through-hole drilling across a range of workpiece materials. Primary materials include cast iron, non-ferrous metals, stainless steel, and steel. Secondary material compatibility extends to cobalt, glass, graphite, iron alloys, nickel, titanium, and titanium alloys. The 5xD flute-by-diameter ratio and 14.00 mm maximum drilling depth make it a practical choice for close-tolerance production environments where micro-diameter precision is critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in micro-diameter drilling
• AlCrN coating improves thermal stability and extends tool life in high-temperature cuts
• 140-degree drill point angle reduces thrust force and improves centering accuracy
• Coolant-through design supports chip evacuation and heat management at depth
• DIN 6535 HA compliant straight-cylindrical shank for secure, standardized toolholder fitment
• Compatible with blind hole, stack, and through-hole drilling applications

Compatibility

Designed for use in toolholders accepting a 0.1180-inch (3.00 mm) straight-cylindrical shank conforming to DIN 6535 HA. Suitable for machining cast iron, non-ferrous metals, stainless steel, steel, cobalt alloys, glass, graphite, iron alloys, nickel, titanium, and titanium alloys. Part of the DB133-05-A1 series.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle and toolholder are fully stopped and de-energized before changing bits. Verify shank diameter and toolholder bore tolerance before seating the bit to avoid runout. Follow the toolholder manufacturer torque and clamping procedures appropriate for the shank size and application.
