Title: Won't hold the bit
Review: I used this over the weekend on a project that required a lot of drilling. I could not get the chuck to tighten. Holding the collar while pressing the trigger caused the chuck to slip, regardless of what I tried to do (push/pull the collar while tightening, etc.). I finally put it in my steel desk vice, got channelock pliers and stuck an old screwdriver in the collar hole (looks like where a chuck key should go, but the handle on my chuck key wouldn't fit). I tightened it alright, it worked great until I wanted to change bits and it took me 10 minutes to reverse my tightening using the same vice and pliers. Afterword, same story, it would not tighten just would slip constantly. Am sending it back and trying the Makita chuck.P.S. I have DeWalt cordless hammerdrill and impact driver and love their products, have had several generations of their products with no problems, but this one chuck is a disappointment.
Is this product review negative?
