30B068 - Walter 7-Inch Type 1 Closed Cutting Guard for Model 6170

Technical Overview of the Walter 30B068 Closed Guard

The Walter 30B068 is a specialized safety accessory designed for use with 7-inch angle grinders, specifically engineered to fit Walter models such as the 6170. This guard features a "Closed" or "Type 1" design, which is a critical requirement for industrial safety standards when performing cutting operations with bonded abrasive wheels. Unlike standard Type 27 (depressed center) guards which leave the bottom of the wheel exposed for grinding, a Type 1 closed guard covers a significant portion of the wheel's periphery and sides.

Constructed from high-grade, impact-resistant steel, this guard is built to withstand the rigorous demands of heavy industrial environments. Its primary function is to contain wheel fragments in the unlikely event of a wheel burst, directing high-velocity debris away from the operator. Furthermore, the closed design significantly improves the capture and deflection of sparks and abrasive swarf, contributing to a cleaner and safer work environment. The 30B068 integrates seamlessly with the tool's existing mounting mechanism, ensuring a secure fit that does not vibrate loose during operation.

For MRO managers and safety officers, ensuring that angle grinders are equipped with the correct guard for the specific application is a matter of regulatory compliance (OSHA/ANSI). When switching from grinding discs to cutting wheels, the installation of this closed guard is mandatory to meet these safety protocols. The Walter 30B068 offers a robust, reliable solution that maintains the operational efficiency of the tool while prioritizing operator protection.
