Mytee Products 66″x4″x1/2″ Cutting Edge
Size and format: 66″ x 4″ x 1/2″. Material: 16Mn steel with heat-treated properties for enhanced hardness and wear resistance. Mounting options include bolt-on or weld-on. The blade type is a single bevel, designed to deliver efficient cutting and easier material release, while the heat treatment supports higher yield strength at 343 MPa. Suitable for a range of loader and excavator applications where a lighter-duty edge is acceptable but still rugged.
Mytee Products 60″x4″x1/2″ Cutting Edge
Size and format: 60″ x 4″ x 1/2″. Material: 16 Mn steel with weld-on and bolt-on mounting compatibility. Features a single bevel blade and heat-treated construction. Yield strength is listed as 900 MPa, indicating strong resistance to deformation under heavy loads. Hardness specification ranges from 36-40 HRC, providing good wear resistance for typical earthmoving tasks without compromising toughness.
Titan Attachments 72″ Cutting Edge
Size and format: 72″ x 4″. Material: 1055 carbon steel. Unpainted finish that allows field hardening and customization. Mounting options include weld-on and bolt-on after drilling holes. This edge is designed for sturdy performance in demanding digging and trenching work, with straightforward installation and routine maintenance in mind.
Titan Attachments 72″ Carbon Steel Edge
Size and format: 72″ x 6″. Material: 1055 carbon steel, unpainted. Weld-on or bolt-on mounting options allow flexible installation on many bucket styles. This edge emphasizes durability and resistance to wear while providing reliable performance in heavy-duty applications. The unpainted finish keeps options open for field treatments or coatings as needed by users.
Titan Attachments 66″ Carbon Steel Edge
Size and format: 66″ x 4″. Material: 1055 carbon steel, unpainted and ready for bolt-on or weld-on mounting. It offers a balance between edge length and thickness, suitable for moderate to heavy digging conditions. The unpainted design supports field customization and coatings to extend service life in harsh environments.
Buying Guide: Key Considerations When Selecting Excavator Bucket Edges
Material selection matters for wear life, impact resistance, and work rate. Carbon steel edges like 1055 offer strong performance at a reasonable price, while 16Mn and boron-containing boron steel variants provide additional hardness and wear resistance. Consider the following:
- Workload and material: Harder edges resist wear on abrasive soils but may be more brittle under heavy impact. Softer edges can absorb impact but wear faster in sandy or rocky soils.
- Mounting method: Bolt-on edges offer quick swaps; weld-on edges are typically more secure for high-load tasks. Ensure compatibility with your bucket and machine model.
- Edge profile: Single bevel blades improve cutting efficiency and release, but some tasks benefit from a double bevel or a stepped edge for multi-purpose use.
- Hardness and heat treatment: Higher hardness (e.g., 36-40 HRC or 500 HB equivalent) boosts wear resistance but may reduce toughness. Balance needs with working conditions.
- Maintenance and replacement: Consider ease of replacement, availability of spares, and whether you prefer unpainted edges (easier field treatment) or painted finishes for corrosion protection.
- Cost vs. longevity: While more wear-resistant edges may cost more upfront, longer service life can reduce downtime and total cost per hour of operation.
- Compatibility: Verify length, width, and thickness match your bucket’s throat and足 mounting holes to avoid fit issues and ensure secure attachment.
