Electro Arc Bolt Eater is a portable metal-disintegration system designed for removing large broken or seized bolts, studs, HSS tools, carbide tooling and other difficult metallic obstructions.
Designed to take the equipment to the repair rather than the repair to the machine shop, Bolt Eater provides a specialised solution for demanding maintenance and extraction work.
Large Bolt RemovalDesigned for broken and seized bolts and tooling from 1/2 inch and larger.
Portable OperationMobile system designed to be taken to the equipment requiring repair.
Precision ControlServo-controlled disintegrating head with controlled feed.
Difficult Material CapabilityCapable of disintegrating HSS, carbide tooling, drill bits and large metallic fasteners.
Overview
When Conventional Removal Becomes the Problem
Broken and seized bolts can turn a maintenance job into extended downtime, particularly when drilling, torching or conventional extraction methods are impractical or risk damaging the surrounding component.
The Electro Arc Bolt Eater uses metal-disintegration technology to remove unwanted conductive material through controlled electrical arcs.
Its portable configuration allows the system to be positioned at large equipment and difficult repair locations, making it particularly relevant for turbines, heavy machinery, large studs, drilling equipment and critical plant maintenance.
