Frequently Asked Questions

What is the CHICAGO-LATROBE Screw Machine Drill Bit 78725 used for?

This 29/64" solid carbide screw-machine length drill bit is designed for general-purpose drilling in production environments. It creates precise holes in materials like steel, stainless steel, and cast iron. The 118° 4-facet point reduces thrust and improves chip evacuation, making it ideal for CNC and automatic screw machines.

What are the specifications of the CHICAGO-LATROBE 78725 drill bit?

The CHICAGO-LATROBE 78725 is a 29/64" diameter solid carbide screw-machine length drill bit with a 118° 4-facet point. Its decimal equivalent is 0.4531 inches. The carbide construction provides hardness and wear resistance for high-speed drilling in ferrous and non-ferrous materials.

Where to buy CHICAGO-LATROBE 78725 drill bits worldwide?

3G Electric supplies the CHICAGO-LATROBE 78725 drill bit to customers worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this precision tool to any country.

How to select the correct CHICAGO-LATROBE screw machine drill bit?

Select based on hole diameter (29/64"), material type, and machine rigidity. For steel and cast iron, the 118° 4-facet point reduces walking and heat buildup. Ensure your spindle speed and feed rate match carbide tooling recommendations. CHICAGO-LATROBE bits are optimized for screw machines and CNC lathes.
