Walter-titex 7577887 Micro Drill Bit 1/16 Inch Carbide

Product Description

The WALTER-TITEX 7577887 is a solid carbide micro drill bit designed for precision drilling in demanding industrial and metalworking applications. It carries a 1/16 inch (0.0625 inch) diameter and an AlCrN coating that resists heat and wear at high cutting speeds. The 140-degree drill point angle promotes accurate entry and reduces walking on hard surfaces. At 2.3620 inches overall length with a 0.7090-inch flute length, this bit is built for controlled, repeatable hole-making where tight tolerances matter. It is installed and used by machinists, tool-and-die technicians, and CNC operators.

This 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 metal, stainless steel, and steel. Secondary materials include cobalt, glass, graphite, iron alloy, nickel, titanium, and titanium alloy. The coolant-through design supports internal coolant delivery, making it appropriate for deeper holes and high-production runs where chip evacuation and thermal management are critical. It belongs to the DB133-08-A1 series and follows a right-hand cutting direction.

Key Features

• Solid carbide construction for rigidity and long tool life in hard and abrasive materials
• AlCrN coating provides heat and oxidation resistance at elevated cutting temperatures
• 140-degree point angle reduces thrust and improves self-centering on entry
• Coolant-through capability supports chip evacuation and extended tool life in deep holes
• Straight-cylindrical shank (0.1180 inch diameter) compatible with standard collets and drill chucks
• Flute-by-diameter ratio of 8xD with a maximum drilling depth of 15.00 mm

Compatibility

Designed for use in CNC machining centers, drill presses, and multi-spindle equipment that accept a straight-cylindrical shank with a 0.1180 inch (3.00 mm) shank diameter. Conforms to DIN 6535 HA shank standards.

Installation Notes

This tool is installed by qualified machinists or CNC technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight-cylindrical shank fully in the collet or chuck and verify runout before beginning a cut. Do not exceed the recommended maximum drilling depth of 15.00 mm, and use internal coolant where available to maintain tool life and surface finish.
