Description

If you've got a lathe tool block with a bigger bore but you need to hold a smaller tool, this reduction sleeve is your answer.

It's a CME Type-C bushing with a 1 1/2 inch outer diameter and a 1 inch inner diameter – so you can step down the toolholding size without swapping out the whole block.
Shank length is 3 1/4 inches, and overall length is 3 1/2 inches, which gives you plenty of grip and stability.

It's made from solid steel, so it's tough as nails.

No vibration or distortion issues even during heavy machining passes.
That's a big deal because any flex in the toolholder can ruin surface finish or break inserts.
This sleeve stays rock-solid so you can push your cuts harder with confidence.

One cool feature – this is a Type-C sleeve, which means it has side coolant cutouts.
That lets your cutting fluid flow right through to the tool tip, keeping everything cool and lubricated.

That really helps tool life and chip evacuation, especially in stainless or tough alloys.

Just make sure the outer diameter matches your tool block bore exactly – it's a precision fit, which is how it should be.
