Overview
The PFERD EDP 61002 is a Type 27 depressed center grinding wheel engineered for general-purpose metalworking applications. With a 4-1/2″ diameter and aluminum oxide abrasive, this wheel delivers consistent material removal across steel, stainless steel (INOX), and cast iron surfaces. The INOX construction ensures compatibility with stainless steel grinding without ferrous contamination.
Key Features
- Type 27 depressed center design for safe angular grinding and edge work
- Aluminum oxide abrasive with 24 grit for coarse stock removal
- INOX designation—manufactured without ferrous, sulphurous, or chlorinated fillers to prevent surface contamination
- High stock removal rate with smooth grinding action at low contact pressure
- Reinforced bonding for durability and long service life
- Suitable for both high-power and low-power angle grinders
