This is a quality product.
I found the seller to be highly customer oriented and a pleasure to do business With. I would use this seller again due to the amazing customer service.

Fits Jabobs 633C perfectly
Fits Jacob’s 633C on a craftsman 15 1/2 inch drill press perfectly. I’ve used offbrand chuck keys in the past and they never fit just right. This is a nice key.

Good and strong
I can not imagine what Sheerness and Thickness have to do with a chuck key, but, this one works fine. The one that came with the drill press is spring loaded and jumps out on the floor. This one allows me to remove it when I am ready. It fits in the same holder as the old one and is plenty strong.

JUST ALRIGHT.- WASN'T PERFECT!!
THIS WORKED BUT IT WAS A LITTLE SMALL. UPON ORDERING I COULDN'T FIND THE INFORMATION NECESSARY TO SEE IF IT WOULD FIT MY DRILL PRESS.

Worked Great
The Key that shipped with my Brand Name drill press was made out of chinesium -- the teeth on the OEM key began to wear on day one. This new key was a welcomed replacement. It is a nice positive fit in the Jacobs chuck and it shows no sign of wear.
