Frequently Asked Questions

What is the KEO 55583 countersink used for?

The KEO 55583 is a 110° six-flute countersink used for deburring and chamfering holes in metal. Its cobalt construction suits harder materials like stainless steel. The six-flute design produces a smooth finish, ideal for precision machining and fabrication where a clean, burr-free edge is required.

What are the specifications of the KEO 55583 countersink?

The KEO 55583 is a 110° countersink with six flutes and a 5/16 in body diameter. It is made from cobalt for durability in tough materials. The manufacturer part number is 55583, and it is designed for smooth-finish applications. KEO is the OEM brand.

Where to buy the KEO 55583 countersink worldwide?

You can source the KEO 55583 countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply this item to procurement teams and engineers globally.

How to select the right KEO countersink for my application?

Select the KEO 55583 for 110° countersink angles and materials requiring a smooth finish, such as stainless steel. Match the 5/16 in body diameter to your hole size. For harder materials, the cobalt construction provides heat resistance. Always verify the flute count and angle against your machining requirements.
