ProStaff Review: Milwaukee M18 FORCE LOGIC Knockout Tool

Share With:

Jon Block, LH Block Electric Company, LLC, Bartlett, Ill., got the chance to get out of the shop and use the Milwaukee M18 FORCE LOGIC Knockout set (model #2677-23) out in the field with one of his foreman, Bruce, and an apprentice.

“The old hydraulic system would have taken 3x as long.” Jon Block of LH Block Electric Company, LLC takes the Milwaukee M18 Force Logic Knockout Tool out for a spin.

“Bruce was super excited to try it out and couldn’t wait to use it. One of the first things we both loved about it was the punch and dies themselves. The cross lines on the MILWAUKEE EXACT die helped us get each punch exactly right and on the mark.  We then began punching a series of 3/4”, 1”, and 2” holes and we both marveled at the ease and quickness of changing the punches back and forth,” says Block.

When using the old hydraulic knockout sets, someone always had to hold up the press and one guy would take off the die or punch. The press was always heavy and cumbersome and a hassle, and would leak hydraulic oil if not tightened properly. Granted, Block had one of its old trusty hydraulic knockout sets for 45 plus years and it did a great job for a very long time.

“My Father used this set when he was an apprentice so it’s had it fair share of use. My hope is that this new Milwaukee punch set will hold up just as well. It seems very well constructed and has that old school Milwaukee marketing slogan  ‘Nothing but Heavy Duty’ feel to it,” says Block.

Punching knockouts is a one-person job now for LH Block. “We can do it from any position, which helps make it easier to use while up in the air or on a ladder. There are no hoses in the way to fumble around with.”

Overall, says Block, the tools performance itself was, for the most part, smooth as silk. “It took us a few seconds to get the trigger control down, but it was easy to adjust to. The dies are super sharp. I’m hoping that over time they’ll remain that way. I’m interested in how many holes we’d get in one battery, but we finished off 13 holes and it still had a full charge.

“My foreman is in love with this machine. Our apprentice, after very little instruction, was able to use it just as well. My guys always thought the best inventions in our trade was the Milwaukee M12 Bandsaw and the impacts. But I think they found a new favorite,” says Block.
