Machinists and CNC operators, this 6-inch hydraulic chuck boring ring is exactly what you need for maintaining precision in your lathe work.

Made from hardened steel with a solid 45-50 degree hardness, this thing is built to last through serious use.

The adjustable design works for both outer clamping and inner clamping operations, giving you flexibility for different jobs.

What's really impressive is how it improves accuracy - we're talking better roundness, truer center alignment, and improved cylinder dimensions without that annoying bell mouth shape that can happen with worn chucks.

The hydraulic pressure adjustment makes sizing quick and consistent, saving you time and effort on setup.

Perfect for CNC lathes, power chucks, and even manual chucks where you need better concentricity and truer soft jaw bores.

If you're dealing with an older chuck that's losing its precision, this boring ring can seriously extend its useful life and improve your workpiece quality.

The control over the oil pressure claw forming ring is noticeably better than trying to work with worn original components.

A must-have for any serious machine shop looking to maintain tight tolerances and quality output!
