works well using drill press. comes in a nice case. arrived in a timely manner

I've been turning pens for over 8 years. This trimmer is brilliant. I've trimmed well over 50 pen blanks with this cutter, wood, acrylic, and wood and acrylic combos. Mount the bank in your drill press and GO SLOW ! If you push it into your blank hard and fast it will tear it up, it's very sharp and catches. This little trimmer is light years ahead of the original HSS trimmers, plus when the cutters dull (I'm guessing at some point they will) simply unscrew and rotate. Well worth the couple buck extra.

Excellent quality and accurately, the carbide cutters are sharp, and the tool does a good job of cleaning the inside of brass tubes. Works perfectly in drill press, I'm not sure I would try to use with a hand drill. Only wish it came with a 3/8 pilot cutter shaft

Overall the construction is very good. The carbide cutters are extremely sharp and placed accurately. The shafts are machined to the correct sizes and the tip bores are also sharp. They do a great job cleaning out the inside of the brass tubes. My only problem with it is a design issue. Being that it only has to cutters for blank trimming, as opposed to the normal 4, it chatters severely. So much that you cannot use it with a hand drill. If you do you wind up with a wavy end on the blank, not the clean, flat edge you bought this tool to create. After I locked it and the blank in my drill press, it cuts like a dream. A standard 4 cutter HSS cutter works much better in a hand drill. If you use your drill press for squaring blanks, it’s awesome. If a hand drill, find one with 4 cutters on the head.

excellent quality
