Milwaukee Electric Tool 49-56-7250 Quickchang Drill Bit Review

Okay, I know that most users probably don't care that the two-pin locking mechanism is always loose on the shaft. It features a ball bearing spring that allows the engagement pins to raise and lower, allowing you to screw in the sleeve before the pins engage. However, the pins, threads and timing for the engagement pins provide the required clearances. an inaccurate procedure and not reliable enough not to stagger during the procedure. The threads break too. I'd rather have a simple lock nut…

I like that they are heavy. However, the movement of the outer part of the pen depends on the operation of a tiny set screw. I haven't used it much and it sat idle for a few years. Now the pen part doesn't slide up and down as easily. Since it's not cheap, I'm curious how long it will last. I hope that at least holds up through the wiring of a house. The pilot drill is also about 2 inches from the holder. Not long enough for multiple tall hole saws. A generous 3.5 inches would be desirable.

This is important to me as I don't have a 1/2" drill bit and wanted to use one of my many 3/8" drill bits to cut holes in the ceiling for 4" recessed lights…
