to R K Tool Inc.

R K Tool, Inc. is a third generation, woman owned, CNC Milling and Turning manufacturing company. We have been providing industry leading quality since 1995. We are located in Sterling Hts., MI and have been servicing the greater Detroit area in multiple industries. Being a family owned business, ownership is personally involved with every aspect of production and each individual part manufactured to be delivered to you.

We are known and trusted for our consistent quality. R K Tool is big enough to provide quality that meet or exceed your standards, yet small enough to provide the personal attention to detail that makes the measurable difference in the finished product.
