Natalie ★★★★★

The key fits perfectly into my lathe's collet chuck, and the machining on the flats is precise enough to turn without slipping. I appreciate that it's a standard size for common adjustments.

Zoe ★★★★★

My 4x25 mm key arrived ahead of schedule and fit perfectly into the chuck key slot on my lathe. The precise machining made swapping out the old one effortless.

Eva W. ★★★★★

Ordered this replacement key for my bench top mill, and it's a perfect fit for the 4x25 mm slot. The Standard option with SKU 1490 matched exactly what I needed for the Sieg industrial gear.
