QUALITY

Precision is a process, not a final check.

Process controls run from the initial application review through packaging. Advanced metrology—including PG-1000, Deltronic comparators, super-micrometers, and Zoller inspection—helps maintain repeatability from piece to piece and order to order.

Quality is remembered long after the price is forgotten.

OUR PROGRESS

Where we came from.
Where we are now.

Ostrem Tool began in 1989 in the basement of Ken Bolds’ home. Today, we operate from a 70,000-square-foot precision manufacturing facility—growth earned by continually investing in our people, technology, and customers.

Our facility has changed dramatically. The standard behind every tool has not.
