Reviews
Michael Turner
I’ve worked in a mid-volume machine shop for over a decade, and the duMONT Minute Man broaches consistently outperform every alternative we’ve tested. The push-type keyway broaches cut with an incredibly smooth feel, and the bushings keep everything tracking dead straight. Even when we switch from steel to non-ferrous materials, the edge retention holds up better than expected. After hundreds of cycles, the consistency is still spot-on, saving us time on rework and inspection.
Sandra Martinez
Running production for power-transmission components means tolerances are tight and repeatability is everything. Our custom duMONT broaches were a game changer. The moment we installed them, we saw reduced chatter, cleaner chip evacuation, and a sharp drop in tool failures. What impressed me most was the precision on longer pulls—no drift, no taper, just clean, uniform slots every time. These tools easily paid for themselves within the first two months of heavy use.
Ethan Reynolds
I manage prototyping for a firearms manufacturer, and one-pass broaches from duMONT have become essential to our workflow. Getting full-depth keyways in one motion without sacrificing accuracy is huge when iterating multiple design versions in a single day. The HSS durability means we can push them hard without worrying about premature wear. It’s rare to find tooling that speeds up R&D without compromising finish quality, but these absolutely deliver.
duMONT Broach FAQ
What materials can duMONT broaches cut?
duMONT broaches are designed to handle a variety of materials including steel, cast iron, non-ferrous metals, and some plastics, making them versatile for most machining tasks.
