NM Attachments - 18" Class 8 Heavy-Duty Tooth Bucket - 4 CAT-Style Teeth - 0.3 cu yd, AR400 Wear Areas [NM-8HD-18]

The NM Attachments 8HD-18 Heavy-Duty Tooth Bucket is an 18-inch excavator bucket designed for machines in the 7–12 ton operating-weight class. Built from high-grade structural steel, it combines heavy-duty construction with AR400 wear protection in critical areas, including the bottom wear straps, side wear plates, and side cutters. The CAT-style teeth configuration is suited to demanding digging work, while the required mounting configuration can be specified to match the excavator and installation needs.

Built for Demanding Excavator Work

The 8HD-18 is a heavy-duty tooth bucket for excavators with an operating weight of 14,000–24,000 lb. Its 18-inch working width provides a focused digging profile for excavation and material-handling applications where a durable tooth bucket is required.

High-grade structural steel forms the main bucket construction, while AR400 wear areas reinforce locations exposed to repeated contact with soil, rock, and other abrasive materials. The wear protection includes the bottom wear straps, side wear plates, and side cutters, helping support durability in high-contact areas during regular operation.

Wear Protection for Extended Service

AR400 wear material is used in the bucket’s critical wear areas to provide added protection where abrasion and contact are concentrated. The bottom wear straps, side wear plates, and side cutters are specifically identified as AR400 components. This construction makes the bucket suitable for excavator work requiring a robust attachment for repeated digging and material handling.

Tooth Configuration and Mounting

The bucket uses a CAT-style teeth configuration, and other tooth options are available. The mounting configuration must be specified before ordering. The exact pin-on or quick-hitch configuration is not verified for this model, so mounting details should be confirmed for the intended excavator and installation.
