Not your average tool supply.
A family-run cutting tool house for CNC shops, built on people who know tools and technology that makes buying them easy. Local in the Bay Area, shipping nationwide.
It started as Just End Mills.
JEM began with one job: give Destiny Tool’s carbide end mills better representation at home, in the Northern California and Bay Area shops that make things. Guy Calamia had founded Step Tools Unlimited and built Destiny Tool, and the new division went to his son, Justin.
That first version of JEM was one person, one product line and a small front lobby office. Justin was the whole team: every customer, every call, every order. Over time, the local manufacturing community came to trust the name, and those customers started asking what else we could help with.
So we brought on more lines, and the name outgrew the business card. Just End Mills became JEM Tool Supply. We moved into larger spaces, built inside and outside sales teams, and started our own delivery service. Destiny Tool is still our sister company, and its end mills are still close to our heart.
The goal hasn’t changed: another level of service, the newest technology we can put to work, and a path of our own.

Family run
JEM has been a family business since 2007. When you call, you get people who know your shop, your machines and what you ran last month, not a phone tree.
The latest technology
In a conservative industry, we’d rather lead. We build our own tools: this site, your prices and live stock, plain-language search, and every order tracked to your door.
A new standard
We’re paving a path for a new standard in tool supply: the know-how of a local counter with the speed of the biggest catalogs, and nobody left on hold.
Serious tools. A little fun on the side.
We take the work seriously: the right tool, straight answers, and orders out on time. Our sticker drops are how we have fun with it, and you’ll find them on toolboxes and machines in shops all over.
