Works great for holding long narrow pieces while turning
Pattern Name: Set Style: Dovetail Jaws
I was able to use this with my cheaper Wen chuck after buying slightly longer hex bolts to attach them. Since I also bought a nicer Wen chuck, I now have two chucks with different jaws for a bargain price. Awesome!

Does not even fit in WEN’s own chuck base!!!
Pattern Name: Set Style: Dovetail Jaws
I bought this set as I already have two WEN chucks. I wasn’t hurry to use the set until months later - today. To my total surprise, the original WEN chuck’s screws do not fit the holes on the set at all!!! I was speechless to see this fact. This is absolutely not because of lack of quality control during production, it is a fault right at design phase not caught throughout the process! Unbelievable. But I have missed the return window for the item. What does Amazon has to say about this situation? ... show more

Didn’t fit my Wen chuck I ordered for these jaws.
Pattern Name: Set Style: Dovetail Jaws
Pretty happy with it after having to drill larger holes for my Wen chuck screws to mount it. It is dead center when drilling blanks so for the price it was worth it. Shouldn’t have to alter to use one with a same brand chuck.

Pen jaws will not fit NOVA chucks
Pattern Name: Set Style: Dovetail Jaws
Looks like a solid set of pen jaws so giving 5 stars but wanted to let people know they do not fit NOVA chucks. Returning solely for that reason.

simi compatiable with la4444
Pattern Name: Set Style: Dovetail Jaws
although not listed as compatiable for for wen lathe chuck la4444. The spacing is compatiable. The holes on the pen lathe need to be drilled and tapped for M6 screws. The screws on the LA 4444 almost fit but just need to be bored and retapped just a little bit.
