A bolt cutter is a pair of pliers for the production process of cutting metal when dividing metal (in Germany according to DIN 8588). It is operated with both arms. Long levers and a double lever mechanism with a corresponding translation allow a large force to be exerted on the hardened cutting surfaces and the workpiece. The form with an angled cutting edge is called a mat cutter . The cutting heads are usually interchangeable.

For lighter applications there is the compact bolt cutter that can be operated with one hand.

Area of ​​use

The langheblige bolt cutters is designed primarily and dimensioned to prepare uncured reinforcement mesh and reinforcing steel in reinforced concrete . Depending on the size and weight of the model, the material thickness that can be processed is between 8 and 13 mm, correspondingly less for harder materials. The ability to quickly cut through screws, pins , wires , bolts , rivets , chains, etc. opens up the field of application for cracking padlocks and bicycle locks and as a burglary tool.

The compact bolt cutter has a wide range of uses in industry and trade for cutting soft and hard wires and piano wire.

More powerful alternatives

Correspondingly more powerful bolt cutters are also manufactured for cutting through larger cross-sections or stronger materials. Hydraulic cutting devices, such as those used in rescue operations by the fire brigade and in Germany by the technical relief organization (so-called hydraulic rescue kit ), can cut solid objects without the dangerous flying sparks of an angle grinder that can be used as an alternative .

There are also pneumatic bolt cutters that work faster than hydraulic cutters.
