Why Choose the Rittal SM2414.500 Contact Cutter?
The Rittal SM2414.500 is a specialist contact cutter for earthing bolts, designed to prepare reliable electrical contact points on painted or coated enclosure surfaces. It enables EMC-compatible preparation of the contact area for components such as earthing straps, helping establish a dependable conductive connection to the enclosure.
The cutter uses a plastic-bound abrasive with an integrated guide pin for accurate positioning in Rittal round system punchings. By locally removing the insulating surface coating around the earthing point, the tool exposes the underlying conductive metal without requiring unnecessary removal of coating from a larger area.
Designed for use with a drill, grinder or similar powered tool, the SM2414.500 provides panel builders and electrical engineers with a quick and repeatable method of preparing earthing contact surfaces. The tool is specifically designed for earthing bolts and is supplied individually for professional enclosure assembly and electrical installation work.

Reliable Preparation of Earthing and EMC Contact Points
Paint and powder coatings provide valuable corrosion protection for electrical enclosures, but they can also act as electrical insulators. Where an earthing strap or similar bonding connection must make conductive contact with the enclosure, the coating around the connection point needs to be prepared correctly. The Rittal SM2414.500 provides a purpose-designed method for exposing the required contact surface around an earthing bolt.
The integrated guide pin helps centre the cutter in compatible round system punchings, while the abrasive surface removes the coating from the contact area. This makes the tool particularly useful during enclosure assembly, modification and electrical installation work where repeatable earthing and EMC bonding points are required. Rittal notes that this contact cutter is not necessary with VX and TS enclosure systems.
