GWS Tool Group

GWS Tool Group acquires Carbide Tools Mfg. Inc.

The acquisition of Carbide Tools Mfg. Inc (CTMI) strengthens GWS capability and capacity in the arena of custom carbide round tooling. From porting tools and reamers to complex form tools and custom end mills, CTMI’s customer-driven mission marries perfectly with that of GWS.


GWS Tool Group acquired Carbide Tools Mfg. Inc., adding capability and capacity in custom round tools for GWS and expanding the GWS manufacturing footprint in the upper-Midwest region of the United States.

Carbide Tools Manufacturing, Inc., in Menomonee Falls, Wisconsin, provides carbide round tools with customer service, supported by grinding equipment, in-house PVD coating technology, and a long-tenured team committed to excellence.

Started in 1992 by President Wayne Riekkoff, Carbide Tools began servicing the greater Milwaukee area manufacturing industries with special carbide round tooling. CTMI expanded their products and services nationwide.

“CTMI has a tremendous reputation for service and ingenuity,” says Rick McIntyre, GWS’ CEO. “Their experience with round tools and commitment to quality perfectly mirrors that of the GWS organization and will further enhance our capacity to support the round tool segment of our business,” McIntyre continued.

“I am very excited for Carbide Tools Manufacturing, Inc. to be joining GWS Tool Group,” says Wayne Riekkoff, President of CTMI. “The skill sets of our business could not align more closely with that of GWS. Being able to plug our facility into the GWS engine will undoubtedly increase customer exposure and fuel future growth for years to come.”
