Frequently Asked Questions

What is KEO Countersink 55340 used for?

The KEO 55340 is a 110° three-flute countersink used in machining to create a conical recess for flat-head screws. It is ideal for deburring holes in metalworking applications across industries like automotive, aerospace, and general fabrication.

What are the specifications of KEO Countersink 55340?

The KEO 55340 is a general-purpose three-flute countersink with a 110° included angle and a 1/4 in body diameter. It is made from cobalt steel for durability in hard materials. The manufacturer part number is 55340.

Where to buy KEO Countersink 55340 worldwide?

3G Electric supplies the KEO 55340 countersink worldwide. We handle full logistics, customs clearance, and delivery to your site. As a global industrial solutions provider, we source and deliver genuine KEO cutting tools to any location.

How to select the right countersink for a job?

Select a countersink based on the screw head angle—110° for flat-head screws per ANSI standards. Match flute count to material: three-flute designs like the KEO 55340 reduce chatter in steel. Cobalt construction suits harder alloys. Always verify body diameter fits your tool holder.
