Shim YE4(LH)

The Aloris Shim YE4(LH) is specially designed for use with the ATB-5L Internal Threading Bar – Left Hand. This durable shim acts as a protective seat between the threading insert and the toolholder, providing precise positioning, enhanced insert stability, and resistance to cutting forces during left-hand internal threading operations.

Crafted from high-quality hardened steel, the YE4(LH) ensures maximum accuracy and protects both the insert and the toolholder from damage. It’s an essential component for achieving optimal performance and longevity when threading with Aloris ATB-5L tools.
