夾頭塊組、5C 六角與方形

The square and hexagonal blocks seated my stock perfectly on the first try, and the lever closer has a solid, positive action. I especially like that the quick-acting rings let me swap collets without hunting for a wrench.

I was pleasantly surprised by how smoothly the lever-operated collet closer works—it really speeds up swapping between the hex and square blocks. The two quick-acting rings are a nice touch for smaller adjustments, and the set covers a solid range from 1/16" to 1-1/8".

The hex block gripped my round stock perfectly without any slipping, and the quick-acting rings save a ton of time on repeat setups. This set covers all the common sizes I need for my lathe work.
