Reliability & Durability

Hyundai breakers are precision designed with trusted and proven components and systems.  Our breakers are designed to be rugged and reliable for longer up time, reduced operating cost and  improved productivity.

Hyundai breakers are manufactured with the high grade of steel and rigid box frame construction.  Product testing is conducted in the design and manufacturing process of all new models insuring optimum durability and reliability.



Two stroke selector system

The 2-stroke selector allows users to change from long stroke to short stroke according to the performance needs for their application.


Multiple chisel types

Multiple chisel types are available in stock for your local Hyundai dealer. No matter what type of material you are engaging, we have the right tool for your needs.


Auto Grease System

An optional auto grease system provides greasing throughout the day, eliminates manual greasing, and increases overall tool life. (Available - HDB140 - HDB250)


TPC System - 2-stage stroke valve (Option)

Allows users to change from short stroke to long stroke based on application and material requirements.


NOK Seal System

Longer seal life versus other breakers in the market is achieved with high quality NOK type seals.


Auto ABF (Anti-Blank Firing) System

Standard on HDB140 - HDB250 models, protects chisel points, bolts and front heads from blank firing regardless of application. Auto control starts and stops breaker operation based on pressure on chisel point.


Hyundai-backed support and warranty

Backed by Hyundai, all Hyundai breakers carry a 1 year warranty and are fully supported by the Hyundai dealer network across North America.


Larger Chisel Diameter

Larger diameter chisel points improve durability and reduces operating cost.
