The excavator cutting edge is a core wear-resistant stress component mounted on the front of an excavator bucket, consisting of the main cutting edge and side cutting edges. It serves as the key connecting 

structure between tooth holders and bucket teeth.Its material is selected based on working conditions: Q345 alloy steel for standard operations, NM360 wear-resistant steel for heavy-duty tasks, and imported HARDOX 

ultra-high-strength wear-resistant steel for severe mining abrasion conditions. Processed by quenching and tempering, it gains high hardness and impact resistance.

Assembled via bolt fastening or groove welding, it mainly functions to cut and scoop materials, effectively protecting the bucket body and directly affecting the excavator’s working efficiency. It is an essential accessory

 for earthmoving, infrastructure construction, mining and other operations.

1.  High Wear Resistance    Made of special materials like NM360 wear-resistant steel and HARDOX ultra-high-strength wear-resistant steel, and strengthened by quenching and tempering processes, it boasts excellent hardness and impact resistance, and can withstand friction and impact in severe working conditions such as earthmoving and mining.2.  Strong Working Condition Adaptability    Divided into two structural types: main cutting edges and side cutting edges, its materials can be flexibly selected according to different scenarios including standard operations, heavy-duty construction and high-abrasion mining, and it is compatible with various excavator bucket specifications.3. High Assembly Convenience    Supporting two assembly methods—bolt fastening and groove welding. Bolt connection enables quick replacement and maintenance, while welding connection is suitable for long-term fixed operation needs, meeting different construction rhythms.4. Dual Functions of Protection and Efficiency Improvement    As a stress-bearing component at the front of the bucket, it not only directly undertakes material cutting and scooping operations to improve construction efficiency, but also isolates the bucket body from direct contact with hard materials, thus prolonging the overall service life of the bucket.

1、What information do I need to find the correct parts for my equipment?

You will need to get near the equipment with a tape measure and share the following information with an Equipment Blades representative:

a. Machine Make & Model

b. Overall length of bucket / moldboard / plow

c. number of pieces

d. Length of each piece

e. Best guess at original thickness X width (front to back / height)

f. number of holes in each piece

g. Bolt Diameter

h. Bolt spacing center to center across each piece

2、What territory do you serve? 

We supply and export wear parts to all over the world. You can buy from us directly.

3、What is your warranty? 

All XZHM Blades products are warrantied by manufacturers defects. Certain products are guaranteed against breakage within a reasonable lifespan of the part. 

4、Does XZHM Blades offer discounts? 

Yes, XZHM Blades offers reseller discounts, high volume discounts, qualified orders.

5、What makes through hardened blades different from standard high carbon blades?

Unlike high carbon blades that are often only surface-hardened, our through hardened blades are heat-treated throughout the entire thickness to achieve uniform hardness. This creates consistent wear patterns as the blade wears down, preventing uneven edge development.

6、How much longer do through hardened blades last compared to standard blades?

Through hardened blades typically last 1.5-2 times longer than comparable high carbon blades in abrasive conditions, significantly reducing the frequency of blade changes and associated downtime.

7、Are through hardened blades worth the higher initial cost?

Yes. While through hardened blades cost about 20-30% more upfront, their significantly longer service life and reduced downtime for replacements make them more economical in the long run. This is especially true for operations where equipment downtime is costly.

8、What applications are through hardened curved blades best suited for?

These blades excel in highly abrasive materials, finish grading operations requiring precision, long-duration grading tasks, hard-packed materials, and applications requiring consistent blade geometry for predictable performance.

9、How do these blades perform in hot weather operations?

Through hardened blades maintain their properties better than surface-hardened alternatives in high-temperature environments, providing consistent performance regardless of weather conditions.

10、Will these blades help with crowning issues?

Yes. Unlike standard motor grader blades that develop an uneven wear pattern known as “crowning,” our through hardened curved blades maintain a straight, clean cutting edge throughout their life, ensuring consistent grading results.
