Product Description

The WALTER Micro Drill Bit (SKU A3143-0.25, MPN A3143-0.25) is a 0.25 mm cobalt micro drill bit with a 118° 2-facet point and regular spiral flute design. This precision tool is manufactured by WALTER for industrial drilling applications requiring fine-diameter holes.

Frequently Asked Questions

What is the WALTER Micro Drill Bit used for?

The WALTER Micro Drill Bit (MPN A3143-0.25) is used for precision drilling of fine-diameter holes in industrial applications. Its 0.25 mm diameter and 118° 2-facet point make it suitable for micro-machining tasks in electronics, medical devices, and aerospace, where tight tolerances are critical.

What are the specifications of the WALTER Micro Drill Bit?

The WALTER Micro Drill Bit (SKU A3143-0.25, MPN A3143-0.25) has a 0.25 mm diameter, a 118° 2-facet point, and a regular spiral flute design. It is made of cobalt for enhanced hardness and heat resistance, and is manufactured by WALTER for precision micro-drilling applications.

Where to buy the WALTER Micro Drill Bit worldwide?

You can source the WALTER Micro Drill Bit (MPN A3143-0.25) through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring the tool reaches your facility reliably.

How to select the right WALTER Micro Drill Bit for my application?

To select the correct WALTER Micro Drill Bit, match the diameter (0.25 mm) and point geometry (118° 2-facet) to your hole size and material. Cobalt construction suits harder materials like stainless steel. For regular spiral flutes, use in general-purpose micro-drilling. Consult WALTER's technical data for specific feed and speed recommendations.
