Frequently Asked Questions

What is the CHICAGO-LATROBE Countersink 56876 used for?

The CHICAGO-LATROBE 56876 is a 100° three-flute countersink used for deburring and countersinking holes in metal, plastic, and wood. It creates a conical recess for flat-head screws and is common in automotive, aerospace, and general fabrication. The 3-flute design reduces chatter for a smoother finish.

What are the specifications of the CHICAGO-LATROBE Countersink 56876?

The CHICAGO-LATROBE 56876 is a general-purpose three-flute countersink with a 100° included angle. It has a 1/4 in body diameter and a 3/16 in shank. The tool is designed for use in drill presses and handheld drills. The 3-flute geometry provides balanced cutting and efficient chip evacuation.

Where to buy the CHICAGO-LATROBE Countersink 56876 worldwide?

3G Electric supplies the CHICAGO-LATROBE Countersink 56876 worldwide. As a global industrial distributor since 1990, we handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time. We source and deliver this tool to any country.

How to select the correct countersink for a project?

Select a countersink by matching the included angle to your screw head (e.g., 100° for metric flat-head screws). Choose flute count based on material: 3-flute tools like the CHICAGO-LATROBE 56876 reduce chatter in harder materials. Ensure the shank diameter fits your drill chuck. For deburring, a 3-flute design provides a clean edge.
