Zestaw kołnierzyków ograniczających

The set covers every bit size I reach for daily, and the hex wrenches lock the collars down tight so nothing slips mid-drill. Depth control has been spot-on for my shelf pin holes—no more blowouts on the backside.

The hex wrenches that come in the set fit the set screws perfectly, so no hunting for the right Allen key. The collars slide on smoothly and the locking mechanism holds firm at depth, which makes repeat holes way more consistent.

The depth stop collars lock down tight on my 1/4" and 3/8" bits without any slipping mid-drill, and the two hex wrenches mean I always have one within reach on the bench. It's a solid little set for the money.
