Company Profile

For over five decades, RobbJack has practiced a simple, but powerful mission – to lead our industry by serving our customers.

Established in 1959, RobbJack Corporation specializes in the engineering, manufacture and sale of solid carbide cutting tools. We continue to offer the broadest line of carbide end mills with the closest tolerances available for CNC milling equipment. In addition, we manufacture solid carbide slitting saws and PCD diamond-tipped routers, and provide physical vapor deposition (PVD) coating services.

The benefits of high-speed solid carbide tools are as compelling today as they were 50 years ago. With today’s emphasis on process efficiencies for increased profitability, users realize that properly engineered tooling offers not only closer tolerances and longer life, but extremely high feed rates. RobbJack has worked with several aerospace partners since 1974, to support the demand for superior performance, with progressively more challenging application requirements.

RobbJack Corporation has been employee-owned for more than 25 years, which is the average term of service for over 20% of the staff. The management team has a combined 185 years of experience in the cutting tools industry. Whether your needs are for standard stocked items, or customized tools for your specific application, this experience is here to help you. We define “Service” in our customer’s terms, delivering consistently superior quality products and solving problems quickly and effectively.

An End Mill Designed to Control Chatter
This end mill design enables it to vibrate at the same frequency as the workpiece, preventing vibration from turning into chatter.

Amerimold 2017

Amerimold: Moldmaking's Biggest Show Captures Current Metalworking Technology
Many of the emerging developments and key trends in metalworking technology were represented at this show, making it a revealing cross-section of current advances.

A Practical Approach to Milling Titanium
When the right cutting tool, toolholder, cutter paths and machining parameters are applied intelligently, a shop may have more capability to mill titanium effectively than it recognizes.

Drills Offer Improved Shearing of Composites
RobbJack/Crystallume will highlight a variety of cutting tools, including its PCD drills, which feature a solid diamond tip with geometry designed to shear better than typical flat-plane drills.

End Mills Laser-Measured for Higher Accuracy
The RobbJack Group’s Crystallume division will present enhancements to its Mold Maker line of end mills that are smaller than 1/4" (6 mm) in diameter.
