Air Angle Grind. Service Kit Housing & Muffler (1-4/8) For At0013

At a Glance: Housing and muffler service kit for the AT0013 Proline—restores body fitment and helps reduce exhaust noise while keeping airflow working as intended.

A grinder body does more than “hold the parts together” — it keeps alignment true, protects internals, and routes air where it should go. The AirCraft AT0013-SK09 Service Kit is a housing and muffler refurbishment kit for the AirCraft AT0013 125mm Proline air angle grinder. It supplies key housing and exhaust muffler-related components used in the tool body assembly. This kit is ideal if the housing has been damaged, cracked or worn from hard use, or if the exhaust/muffler section has become noisy, restricted or compromised. Replacing these parts helps restore correct fitment, improves user comfort, and keeps the grinder running with cleaner airflow control.

A compromised housing can cause alignment issues and extra vibration. A tired muffler can make the grinder unnecessarily loud and uncomfortable on long shifts. This kit tackles both where it matters.
