Customer Reviews (4.2 / 5 · 5 reviews)

Leo ★★★★★

The fit on my SX3.5 was spot-on, the mounting holes lined up perfectly without any fiddling. The casting feels dense and well-machined, a solid replacement that should last a good long while.

Emma M. ★★★★★

The fit on my HiTorque mill was spot-on—no filing or fiddling to get the spindle seated properly. It’s a solid, genuine replacement part that feels every bit as sturdy as the original, and knowing it’s compatible with the SIEG SX3.5 gives me peace of mind if I ever need to swap it.

Madison ★★★★☆

Swapped out the original housing on my SX3.5 and this one bolted right up without any filing needed. The casting is noticeably cleaner than the old part, which saved me some cleanup time. Only minor gripe is the paint finish isn't perfectly uniform on the inside.
