The Right Tools for Micro Grooves
Mack Tool and Engineering used modified inserts to create micro-grooves, but they were prone to breaking. After switching to Thinbit Groove ‘N Turn tools from Kaiser Tool, the company experienced increased tool life.

In the Groove for 50 Years
It’s an American success story. In 1964, William and Hazel Kaiser founded a company to produce and market Thinbit, an innovative line of grooving tools. At first, the business operated out of the couple’s attic and garage. Fifty years later, the Kaiser Tool Company’s products continue to help shops such as Mack Tool and Engineering with successful solutions for demanding grooving applications.

10 Considerations When Using Grooving Tools
The dynamics of chip formation and evacuation make grooving in turning operations unique in almost every way. Innovative insert designs and coatings can improve your grooving operation, but to be completely successful, there are some other things you should know.

OD Grooving Tool as Rougher

Multitasking Tools Cut More Than Grooves
Once, grooving tools were only thought of for making grooves or cutting off the part. Improved designs, materials and coatings make them perfect sense as all-purpose tools under the right conditions.
