Everdigm EHB Series Front Head For Chisel Seat Protection And Hammer Nose Rebuild

Product Introduction

The Everdigm EHB Series Front Head For Chisel Seat Protection And Hammer Nose Rebuild is a key structural replacement part used in excavator-mounted hydraulic breaker hammers. It is suitable for Everdigm EHB Series hydraulic breakers, including common models such as EHB02, EHB04, EHB05, EHB13, EHB17, EHB20, EHB25, EHB30, EHB40, and EHB50.

The front head is the lower body section of a hydraulic breaker. It holds the chisel, inner bush, outer bush, rod pin, retainer system, and lower guide structure. During breaking work, the chisel receives impact force from the piston and transfers that force into concrete, asphalt, rock, pavement, and hard ground. The front head supports this impact area and keeps the working tool in the correct position.

When the front head is worn, cracked, deformed, or damaged around the bushing seat or rod pin hole, the breaker may suffer from tool shaking, chisel misalignment, pin damage, abnormal noise, front-end looseness, weak impact, and fast wear of related parts. In serious cases, a damaged front head can affect the piston strike line and shorten the service life of the whole hydraulic breaker.

This product is an aftermarket replacement front head compatible with Everdigm EHB Series hydraulic breakers. The Everdigm name and EHB model references are used only for compatibility identification.

Material

Our Everdigm EHB Series front heads are commonly produced from selected alloy steel or customer-specified material according to breaker size, working condition, and repair requirement. A front head must have strong structural strength, good impact resistance, stable hardness, and reliable machining accuracy.

The front head works in a harsh lower impact area. It is exposed to dust, stone particles, concrete fragments, repeated tool movement, and strong shock load. The bushing seat, rod pin hole, chisel guide area, and mounting surfaces must be strong enough to handle long-term breaker operation.

Heat treatment and precision machining are important for front head production. Proper processing helps improve strength, fitting accuracy, and service stability. Accurate machining of the bushing position and pin hole can help the chisel move more smoothly and reduce abnormal wear on the inner bush, outer bush, rod pin, and chisel shank.

Product Features

The main feature of the Everdigm EHB Series front head is lower hammer structure support. It is not only a housing part, but also the main guide body for the working tool. The front head must hold the chisel securely while allowing controlled movement under impact.

The chisel seat and bushing bore are critical areas. If these positions are worn or out of tolerance, even new bushings may not fit correctly. This may cause the chisel to shake, tilt, or wear unevenly. A properly machined front head helps keep the chisel aligned and improves impact energy transfer.

The rod pin hole is another important area. If the pin hole becomes enlarged or damaged, the rod pin may loosen or wear quickly. This can increase stress on the chisel groove and may lead to tool drop or front-end failure. Replacing the damaged front head in time helps protect the breaker structure and reduce repeated repair.

This front head can be supplied for hydraulic breaker rebuild projects, front-end repair, chisel seat restoration, spare parts replacement, and workshop stock. It can also be ordered together with chisels, inner bushes, outer bushes, rod pins, pistons, seal kits, diaphragms, cylinders, through bolts, side bolts, buffers, and wear plates.

Main Advantages

The main advantage of the Everdigm EHB Series front head is that it helps rebuild the lower impact structure of the hydraulic breaker. When the front head is correctly matched and accurately machined, the chisel, bushing, and rod pin system can work more smoothly.

For demolition contractors, a strong front head helps the breaker handle concrete slabs, foundations, walls, road surfaces, and reinforced structures. For road repair and municipal construction, it supports stable chisel movement during asphalt removal, curb breaking, trenching, and pavement maintenance. For quarry and stone breaking work, the front head must resist continuous vibration and tool load.

Timely replacement of a damaged front head can prevent larger repair costs. If a worn front head continues working, it may damage new bushings, rods pins, chisels, pistons, and even the cylinder alignment. Replacing the front head during a breaker rebuild can improve overall hammer stability and extend the service life of related parts.

For repair workshops and spare parts dealers, the front head is a high-value structural part. Supplying the correct Everdigm EHB Series front head helps customers complete hydraulic breaker overhaul work more efficiently.
