Review on Upgrade Your Tool Kit With The Hymnorq Keyless 3-Jaw Drill Chuck Adapter For Precise Drilling And Milling by Alfredo Testerman

I was hoping that I would get one that was true and accurate but I didn't.It was about 2mm off center which made it impossible to drill straight and accurate holes. The shaft was perfect but the actual chuck was manufactured crooked so any drill bit inserted was at least 2mm off with excessive run out. When you are drilling 3 & 4 mm holes, you can't have that error or else you will ruin your work!I ended up purchasing the DeWalt DW0521 for $29.95 from Lowes. It was perfect, true and straight!Sent this one back the same day and did not reorder.
