Walter-titex 7233424 Micro Drill Bit 0.0161 in Solid Carbide

Product Description

The WALTER-TITEX 7233424 is a solid carbide micro drill bit designed for precision drilling in demanding industrial and machining applications. Built to DIN 1899 standards, it features a 118-degree point angle and a 0.0161-inch diameter, making it well-suited for extremely small-hole work where dimensional accuracy is critical. The right-hand cutting geometry and parallel web configuration promote clean, consistent chip evacuation. With an overall length of 25 mm and a straight-cylindrical shank measuring 1.00 mm in diameter, this bit is compatible with standard collet and chuck systems used in precision machining environments. Installation and operation are handled by machinists and CNC operators working in metalworking and fabrication settings.

The 7233424 is engineered for blind hole, through hole, and stack drilling operations. Its primary workpiece material compatibility includes alloy steels, titanium alloys, and non-ferrous materials, covering ISO material codes K, M, N, O, P, and S. The DB130 Advance series is built around micro-diameter performance, where flute geometry and carbide substrate selection directly affect hole quality and tool life. The bright/uncoated finish is appropriate for materials where coating adhesion or thermal compatibility is not required. This bit is a solid choice for aerospace, medical device, and precision component manufacturing workflows.

Key Features

• Solid carbide construction for rigidity and wear resistance in micro-diameter drilling
• 118-degree point angle for precise centering and clean entry on small-hole work
• Right-hand cut with parallel web configuration for consistent chip flow
• Flute-to-diameter ratio of 5xD with a 3.00 mm flute length and 2.00 mm maximum drilling depth
• Diameter tolerance of +0.000 to +0.004 mm for tight hole tolerances
• Meets DIN 1899 standard for micro drill bits
• Bright/uncoated finish suitable for alloy, titanium alloy, and non-ferrous workpiece materials

Compatibility

Designed for use with alloy steels, titanium alloys, and non-ferrous materials (ISO material codes K, M, N, O, P, and S). Suitable for blind hole, through hole, and stack drilling applications. The straight-cylindrical shank is compatible with standard collet and precision chuck toolholding systems accepting a 1.00 mm shank diameter.

Installation Notes

This bit is intended for use by qualified machinists and CNC operators. Ensure the machine spindle and toolholder are fully stopped and de-energized before installing or removing the bit. Use a precision collet or chuck rated for the 1.00 mm shank diameter to prevent runout, which is especially critical at micro diameters. Do not exceed the maximum drilling depth of 2.00 mm, and verify coolant-through is not required for the application, as this bit does not support internal coolant delivery.
