Description

The NM Attachments NM-6HD-12 12-inch Class 6 Heavy-Duty Tooth Bucket is built for demanding excavator work in sand, gravel, clay, and utility trenching applications. Part of NM Attachments’ 6HD series, this tooth bucket combines high-grade structural steel construction with AR400 steel in key wear areas, including the bottom wear straps, side wear plates, and side cutters. Its standard CAT-style tooth configuration provides an aggressive digging edge for material penetration, making it suited to general excavation and trenching work with compatible 6–7 ton excavators.

Heavy-Duty Construction for Excavation Work

The NM-6HD-12 is designed as a durable digging attachment for applications where the bucket encounters abrasive material and repeated ground contact. The main structure uses high-grade structural steel, while AR400 wear steel is used throughout the identified wear areas. This includes the bottom wear straps, side wear plates, and side cutters, helping reinforce the areas exposed to abrasion during digging, loading, and trenching.

With a nominal working width of 12 inches, the bucket is configured for narrower excavation work and trenching. The supplied product specification identifies a capacity of 3.75 cubic feet and three CAT-style teeth, providing a defined digging profile for breaking into and moving common excavation materials.
