Sawzall Blades for Metal: Cutting Through the Confusion
Sawzalls, also known as reciprocating saws, are fantastic tools for making quick and rough cuts in various materials, including metal. But with a wide array of Sawzall blades available, selecting the right one for metal cutting can be daunting. This Sawzall blades for metal review dives into different blade types, material suitability, and key features to consider for efficient metal cutting.
There are three primary types of Sawzall blades designed for metal: bi-metal, demolition, and carbide-tipped blades. Bi-metal blades offer a good balance between flexibility and durability, making them suitable for general-purpose metal cutting. Demolition blades prioritize speed over longevity and are ideal for fast cuts in thin or soft metals. Carbide-tipped blades are the toughest option, featuring teeth reinforced with carbide grit for tackling thick and hard metals.
Matching the blade type to the specific metal being cut is crucial. Bi-metal blades are versatile and can handle mild steel, aluminum, and copper. Demolition blades are suited for thin sheet metal, conduit, and PVC with embedded metal. Carbide-tipped blades are the go-to choice for stainless steel, cast iron, and reinforced metals.
Beyond blade type and material, several features influence Sawzall blade performance for metal cutting. Teeth per inch (TPI) determines cutting speed and finish. Higher TPI blades (18-24 TPI) create cleaner cuts but are slower, while lower TPI blades (6-14 TPI) offer faster cuts with a rougher finish. Blade length impacts reach and maneuverability. Short blades (6-inch) provide better control in tight spaces, while longer blades (12-inch or more) offer greater reach for deeper cuts.
Some Sawzall blades come with features like variable tooth profiles for tackling various metals or a wider blade body for increased stability during cuts. Consider the noise level as well, with some blades featuring noise reduction technology.
Choosing the right Sawzall blade for metal cutting depends on the specific application. By understanding the different blade types, suitable materials, and key features, you can select the optimal blade for clean, efficient, and safe metalwork. Remember, prioritizing safety by wearing proper eye protection and gloves is paramount when using any Sawzall blade.
