duMONT CNC History
From duMONT Broaching Legacy to Modern
CNC Indexable Systems
duMONT CNC is a modern Pilot Precision Product brand built on the legacy of The duMONT Company. It extends decades of broaching expertise into CNC machining environments with indexable tooling, replaceable inserts, modular holders, and application-specific support.
Historic duMONT Foundation
Founded by W. Beltram duMont, The duMONT Company became known for precision broaching tools, especially push keyway broaches and related tooling.
Created For Modern CNC Needs
As machining shifted toward CNC centers, live-tool lathes, Swiss machines, and multi-axis platforms, Pilot expanded the duMONT name into a new indexable broaching system.
Acquired By Eric Hagopian
Eric Hagopian acquired The duMONT Company in 2016, preserving the duMONT legacy while creating a path for broader tooling innovation.
Folded Into Pilot Precision
Pilot Precision Products was formed in 2019 to unify duMONT, Hassay Savage, GMauvaisUSA, Magafor USA, and other premium tooling brands under one organization.
A Modern Platform Built on a Historic Broaching Name
The duMONT name traces back to precision broaching tools manufactured beginning in 1945 and formal incorporation in Greenfield, Massachusetts in 1947. Under Pilot Precision Products, that legacy evolved into duMONT CNC: a modern indexable broaching platform designed for CNC machining centers, live-tool lathes, Swiss machines, and multi-axis production.
1945
The duMONT Company begins manufacturing precision broaching tools.
1947
duMont CNC expands the name into indexable systems for today's CNC production environments.

NEW CAPABILITY: Broaching On Advanced CNC Machines
GLOBAL CNC COLLABORATION
Broaching Now Possible On Advanced Turning
And Milling CNC Machines.
To help manufacturers get more from their machining centers, duMONT CNC has partnered with Global CNC to combine our motorized slotting technology with their advanced right-angle interface systems. Together, we expand machine versatility, improve productivity, and reduce the need for secondary operations across a wide range of applications.
Whether you’re running vertical or horizontal machines from Okuma, Mazak, DMG Mori, or other leading platforms, this collaboration delivers a powerful combination of broaching expertise and machine interface innovation. In one application, we developed a custom right-angle head for an Okuma 2SP-2500—providing the clearance, rigidity, and precision that standard solutions could not achieve while opening the door for more automated machining workflows.
What This Partnership Enables
Lower Cost Per Part With Replaceable Inserts
Faster Changeovers That Reduce Machine Downtime
Reduced Secondary Operations With Automation-Ready Workflows
Custom Right-Angle Solutions For Greater Machine Versatility
Why It Matters
By combining duMONT CNC broaching expertise with Global CNC interface knowledge, Pilot can help manufacturers solve complex turning and milling applications that demand precision, access, and process confidence.
