Customer Reviews (4.8 / 5 · 5 reviews)

Julian ★★★★★

The guard lines up perfectly with the mounting holes on my lathe, so installation took under five minutes. It feels sturdy enough to handle regular use without any wobble.

Kevin D. ★★★★★

The bolt holes lined up exactly with the existing mounts on my SC4, so installation took maybe ten minutes. The guard feels solid and hasn't rattled loose during a few hours of turning. Exactly what I needed to replace the worn original.

Carter ★★★★★

The new chuck guard fits perfectly on my SC4, and it’s sturdier than I expected—definitely a solid replacement part. I had it installed in under five minutes, which made the whole repair feel effortless.
