Frequently Asked Questions
What is a CHICAGO-LATROBE 3-flute countersink used for?
A CHICAGO-LATROBE 3-flute countersink creates a 100° chamfer around a drilled hole, allowing screw heads to sit flush with the workpiece surface. It is commonly used in metalworking, machining, and fabrication for deburring and preparing holes for fasteners.
What are the specifications of the CHICAGO-LATROBE 56880 countersink?
The CHICAGO-LATROBE 56880 is a 100° general-purpose three-flute countersink with a 1/2 in body diameter. It is made from black oxide high-speed steel for wear resistance and reduced friction. The 3-flute design provides smooth, chatter-free operation in ferrous and non-ferrous materials.

How to select the right countersink for a machining job?
Match the countersink angle (e.g., 100°) to your fastener head angle. Choose flute count based on material: 3-flute designs like the CHICAGO-LATROBE 56880 reduce chatter in harder metals. Body diameter must exceed the hole size. Black oxide HSS suits general-purpose use; for abrasive materials, consider carbide.
