Satellites. Airplanes. Rockets. Life-saving medical devices. RobbJack makes the carbide tools that do the cutting — which means the work you do here reaches people you will never meet, in ways that matter.
Satellites
01 / 07
01Satellites
A soldier calls home on a birthday. A student overseas video-chats with her parents. A rural clinic gets online for the first time. Every one of those signals bounces off a satellite overhead.
Where our tools come in
Satellite frames, brackets and antenna housings are machined from aluminum and lightweight composites — exactly the cuts our end mills and routers are built for.
02Aircraft
A daughter makes it to the hospital the morning her dad wakes up. A family sees the ocean for the first time. Airplanes shrink the world so people can be there when it matters.
Where our tools come in
An airliner is built from thousands of machined parts — wing ribs, brackets and engine components in aluminum, titanium and heat-resistant alloys. Carbide end mills ground in Lincoln are made for exactly those metals.
03Electric vehicles
Quieter streets. Cleaner air for kids on their way to class. Electric vehicles are changing how the world moves — and how it breathes.
Where our tools come in
Battery trays, motor housings and lightweight aluminum structures are milled at high speed with solid carbide end mills, and slitting saws cut the precise slots in between.
04Rockets
Weather satellites spot a hurricane days before it lands, and a coastal town gets out of the way. GPS guides an ambulance to the right door. Rockets put those satellites in orbit — and the next ones will take us farther than we have ever been.
Where our tools come in
Rocket engines and structures demand tight tolerances in some of the toughest alloys on Earth. That is where precision carbide earns its keep.
05Medical equipment
A ventilator keeps someone’s dad breathing. A veteran walks on a new leg. After cataract surgery, a grandmother sees her grandchildren’s faces clearly again. Medical devices give people their lives back.
Where our tools come in
Implants, prosthetics and surgical instruments are machined from titanium, stainless steel and medical plastics to exacting tolerances — small parts where every thousandth of an inch matters.
06Electronics
The phone that wakes you up. The laptop where a kid writes her first line of code. The wireless signal that lets a small business sell to the world. Electronics speed up every other kind of progress.
Where our tools come in
Device housings — and the molds that shape plastic parts — are cut with carbide end mills, while routers and slitting saws trim, slot and separate the pieces.
07A Certified Green Business
We believe the tools that build the future should be made responsibly. RobbJack is a Certified Green Business: 95% of our power comes from solar and green energy, right here in Lincoln.
How we make them
Carbide is precious. Our GO GREEN reclaim program recycles worn tools, and our regrind service puts used ones back to work — getting the most from every blank.
Every tool we ship carries a little of Lincoln into the world. And the people who make them?
They own the companyThere is no outside owner. RobbJack belongs to its employees through an Employee Stock Ownership Plan (ESOP) — so when you build a better tool here, you are building something that is partly yours.
Company shares go into an account in your name through our Employee Stock Ownership Plan. It doesn’t come out of your paycheck.
Your account grows with the company’s success — so every good tool, every happy customer and every smart improvement builds your future too.
When you retire or leave, your vested account is paid out to you under the plan’s rules — on top of your 401(k).
Eligibility and vesting follow the plan documents — we walk every new team member through them.
A RobbJack tool starts as a plain carbide rod and leaves as a precision cutter. Here are the kinds of work it takes to get it there — and to get it to the people who need it.
Run the CNC grinders that turn solid carbide rod into end mills, routers and slitting saws — and learn how every flute and edge is made.
Measure every critical feature against the print with precision measuring equipment, so the tool that ships is the tool that was promised.
Write and prove the grinder programs that define a tool’s geometry — the craft behind the cut.
Design new geometries and help machinists solve their toughest cuts in titanium, superalloys, composites and aluminum.
Pack, label and ship finished tools to distributors and machine shops across the country and around the world.
Answer customers, process orders, quote tools and keep the business running — customer service is everyone’s job here.
You don't need to walk in a master machinist. We train good people to make great tools — and we have practiced Lean continuous improvement since 2010, so getting a little better every day is simply how we work.
