For over half a century at Toolcraft, LLC the expert craftsmanship of our toolmakers has been elevating the industry standard for precision broach tooling. We fabricated the tool set highlighted here for a customer in the gear manufacturing industry who knew they could rely on us for a superior product and great service.

Used to manufacture large gears, this set of tooling included a broach horn with dimensions of 6.0" in diameter x 16.0" in length, which we fabricated from 8620 steel to provide high surface wear resistance. We fabricated the two 1.5" wide x 18.0" long shims, one measuring 0.250" in thickness, the other 0.187" from tough A2 steel for maximum dimensional stability during heat treatment.

Primary operations consisted of CNC turning and milling to create the part features and geometries. The parts were then case hardened to RC 58-60. The talents of our journeymen grinders were required to hold these components to within tight +/-.0002" dimensional tolerances.

We delivered the tooling to the customer within a 4 week timeframe, where it is now helping them yield high production rates and manufacture the best possible product. Our commitment to excellence is why we achieved a longstanding relationship with this client and continue to do many projects for them.
