What are aviation snips used for in HVAC work?

Aviation snips are used to cut sheet metal when fabricating or modifying ductwork, fittings, and metal components. In HVAC applications, snips allow technicians to make straight cuts, curves, and tight turns in materials such as galvanized steel, aluminum, and stainless steel.

What is the difference between left-cut, right-cut, and straight-cut snips?

Different snip types are designed to control material direction and cut accuracy:

• Straight-cut snips: Best for straight cuts and gentle curves
• Left-cut snips: Designed for cutting tight left curves while directing scrap away
• Right-cut snips: Designed for cutting tight right curves while maintaining control

What gauge metal can aviation snips cut?

The cutting capacity of aviation snips depends on the model and material. Many HVAC-grade snips are designed to cut up to 16 or 18 gauge cold-rolled steel, as well as thicker aluminum and lighter stainless steel used in ductwork and flashing.

What are sheet metal seamers used for?

Sheet metal seamers are used to bend, flatten, and form seams in ductwork and metal panels. HVAC technicians commonly use seamers to close Pittsburgh seams, create hems, bend flanges, or align sections of duct for a secure fit.

What are duct crimpers used for?

Duct crimpers are used to corrugate the ends of round duct or stovepipe so one section can fit inside another. Crimping helps ensure proper airflow direction and creates a tighter connection before fastening or sealing.

What are cleat tools used for in sheet metal work?

Cleat tools are designed to install and secure drive cleats and hanging straps on ductwork. These tools help reduce repetitive motion and strain while improving speed and consistency during duct installation.
