Frequently Asked Questions

What is a CHICAGO-LATROBE 82° countersink used for?

What are the specifications of the CHICAGO-LATROBE 56736 countersink?

The CHICAGO-LATROBE 56736 is a fast-cutting single-flute countersink with an 82° included angle. It has a 1/4 in body diameter and a 3/16 in shank. This tool is designed for general-purpose deburring and countersinking in industrial applications.

How to select the right countersink for a flat-head screw?

Match the countersink angle to your screw head angle—82° is standard for inch flat-head screws. Choose a body diameter slightly larger than the screw head. Single-flute designs like this CHICAGO-LATROBE tool cut fast and clear chips well in softer materials.
