Daemo DMB Standard Series Breaker Chisel Wear Resistant Rock Bit For Excavator

Product Introduction

The Daemo DMB Standard Series Breaker Chisel Wear Resistant Rock Bit For Excavator is designed for excavator-mounted hydraulic breakers used in demolition, road construction, quarrying, mining, trenching, foundation excavation, concrete breaking, and secondary rock breaking. It is suitable for Daemo DMB Standard Series hydraulic breaker hammers, including common models such as DMB50, DMB70, DMB90, DMB140, DMB180, DMB210, DMB220, DMB230, DMB250, DMB300, DMB360, and DMB450.

As the direct working tool of a hydraulic breaker, the breaker chisel plays an important role in impact energy transfer. It contacts concrete, asphalt, hard rock, reinforced structures, and other tough materials during operation. A properly matched and wear resistant rock bit can help improve breaking efficiency, reduce abnormal wear, protect the breaker bushing and front head, and lower maintenance costs.

This product is made for aftermarket replacement use and is compatible with Daemo DMB Standard Series hydraulic breakers. The Daemo and DMB model names are used only for compatibility reference.

Product Features

Our Daemo DMB Standard Series breaker chisel is manufactured from selected alloy steel, commonly 42CrMo or equivalent material, depending on customer requirements. This material is widely used for hydraulic breaker tools because it offers a good balance of strength, toughness, wear resistance, and impact fatigue resistance.

The production process includes forging, CNC machining, heat treatment, and surface finishing. Heat treatment is one of the key processes for breaker chisels. The surface needs enough hardness to resist wear from stone, concrete, and asphalt, while the core must remain tough enough to absorb repeated impact force. A good breaker chisel should not be too soft or too brittle. The correct hardness and toughness help extend service life and reduce the risk of breakage.

Each chisel is produced according to the required model dimensions, including tool diameter, total length, working length, retainer pin groove, and head shape. Accurate machining helps the chisel fit correctly with the front head, bushing, retaining pin, and piston impact area. Good fitting can reduce tool shaking, improve impact energy transfer, and protect other hydraulic breaker spare parts.

Different tool types can be supplied for different working conditions. Chisel type is suitable for directional breaking, trenching, road cutting, and concrete removal. Moil point type is used for general rock breaking and penetration work. Blunt type is suitable for secondary breaking in quarry and mining applications. Wedge type can be used for layered rock, reinforced concrete, and controlled breaking work.

Main Advantages

The main advantage of this Daemo DMB Standard Series breaker chisel is its combination of wear resistance, impact strength, and dimensional accuracy. It is suitable for continuous job site use where hydraulic breakers must work under strong impact force and harsh material conditions.

For demolition contractors, the chisel can be used for breaking reinforced concrete, building foundations, bridge structures, walls, and old pavements. For road construction teams, it is suitable for asphalt removal, road repair, trenching, and municipal engineering. For quarry and mining customers, it can be used for secondary rock breaking, stone splitting, and hard material separation.

A correctly matched breaker chisel can also help reduce the maintenance cost of the hydraulic hammer. If the chisel is too loose, too short, incorrectly grooved, or made from poor material, it may damage bushings, retaining pins, front heads, pistons, and other internal parts. By choosing a proper wear resistant rock bit, customers can improve working stability and reduce unexpected downtime.
