Colton Industrial Tools 97204 | BXA #4 Quick Change Boring Bar Holder, Holds 3/4" & 1" Diameter Tools, Upgraded ZiN Coated Hardware

Quick change holders are incredibly versatile in the machine shop. Found almost exclusively on lathes, they allow you to quickly swap between tools with minimal setup time. BXA #4 holders are designed to hold round shank boring bars, and help to keep the job running smooth. The team at Colton Industrial Tools worked on giving their quick change holders a bit of an edge. They use a Zinc Nitride (ZiN) coating on all of the hardware to give it a more durable and rust resistant finish while allowing for smoother thread action. We think the coating looks pretty good, too.

Colton Industrial holders are made from hardened and ground steel and allow for extra tool capacity over other holders on the market. Colton’s #4 includes a ZiN Coated Bushing so the user can hold both 3/4” and 1” round tools. Colton Industrial Tools has a commitment to support their customers by offering a best in class 5 year warranty on all their products.  These holders are yet another example of Colton Industrial Tools living up to their motto of “Helping Makers Make Better.”
