Multipurpose Oscillating Tool Blades

Style A

Style D

Style E

Cut wood, metal, plastic, and drywall without changing blades. Also known as bimetal blades, these blades have a carbon steel body with high-speed steel teeth. Use these small blades for small jobs, from plunge cutting notches in sheet metal to flush cutting a protruding nail. Mount them to your oscillating tool at any angle to avoid awkward cutting angles and reach into tight spots.

Starlock Blade Mount—They fit Starlock-compatible tools.

High-Speed Steel Teeth—High-speed steel teeth are harder than steel teeth, so they can cut harder materials and last longer than carbon steel blades.

Controlled-Dispensing Lab Spatulas

Curved Blade

A thumbwheel on these spatulas creates small vibrations to dispense tiny amounts of liquids or powder. This makes them a great choice to transfer material bit by bit into a weighing dish. Made from stainless steel, these spatulas are corrosion resistant for use with chemicals, as well as easy to clean and sanitize.

Curved Blade—Spatulas with a curved blade have a slight curve at the tip to keep samples from falling off the end in large quantities. These spatulas lack edges, so they are a great choice when you want to dispense every last speck.

PTFE-Coated Stainless Steel Blade—Spatulas with a PTFE-coated stainless steel blade let liquid and powder slide easily off the blade. The coating meets FDA requirements for use in direct food contact applications.

Long-Life Oscillating Tool Blades for Cutting Wood


Starlock Mount	Open Mount

The teeth are shaped to cut wood without leaving burn marks. To further prevent burning, these blades have a coating that limits heat buildup. Since they stay cool, they resist dulling and getting gummed up with sawdust. Mount them to your oscillating tool at any angle to avoid awkward cutting angles and to reach into tight spots.

Starlock Blade Mount—Starlock-mount blades work with Starlock-compatible tools.

Open Blade Mount—Open-mount blades work with all non-Starlock tools.

Carbide-Tipped Steel Teeth—With carbide-tipped teeth that contain titanium and cobalt, these blades stay sharp 50 times longer than bimetal blades with high-speed steel teeth.

Curved Blade—They have a slightly curved edge, so you can make plunge cuts without having to angle your tool like you would with a straight-edge blade.

Nonsparking Floor Squeegees

1-Ply Blade

Curved Blade

A nonsparking aluminum frame allows you to safely move volatile liquids. The blades resist oil, gasoline, and most chemicals.

Curved Blade—Squeegees with curved blades collect more liquid within the width of the blade than squeegees with straight blades. The handle flips for pushing or pulling.

Fast-Cut Oscillating Tool Blades for Cutting Wood

Curved Blade

Open

Mount

Cut wood twice as fast as standard oscillating tool blades. Also known as Japanese tool blades, each tooth has three bevels ground into it for increased sharpness. The teeth are designed to cut wood without leaving burn marks. Use them for small jobs, from straight and plunge cuts in tight spaces to curved cuts for custom designs. Mount them to your oscillating tool at any angle to avoid awkward cutting angles and to reach into tight spots.

Curved Blade—Curved blades have a slightly curved edge, so you can make plunge cuts without having to angle your tool like you would with a straight-edge blade. This allows for cleaner cuts with less tool vibration. These blades are finished with black oxide for mild corrosion resistance in dry environments.

Black-Oxide High-Speed Steel Teeth—Made of high-speed steel, their teeth are harder than carbon steel teeth, so they last longer and cut harder materials.

Black-Oxide Carbon Steel Body—Since these blades have a carbon steel body, they’re also called bimetal blades.

Open Blade Mount—Open-mount blades work with all non-Starlock tools.

Oscillating Tool Blades for Cutting Thin Metal


	Starlock Mount	Open Mount

With hardened teeth, these blades make precise cuts in screws, nails, thin-walled pipe, and other thin metals. Because of their size, they’re typically used for small jobs, such as making notches in sheet metal. They mount to your oscillating tool at any angle, so you can avoid awkward cutting angles and reach into tight spots.

Starlock Blade Mount—Starlock-mount blades work with Starlock-compatible tools.

Open Blade Mount—Open-mount blades work with all non-Starlock tools. They have a coating that resists heat buildup, so they’ll stay sharp and won’t get gummed up with metal shards.

High-Speed Steel Teeth—The teeth are high-speed steel, so they last longer than carbon steel teeth and cut through harder materials.

Carbon Steel Body—Also known as bimetal blades, these blades have a carbon steel body.

Curved Blade—They have a slightly curved edge, so you can make plunge cuts without having to angle your tool like you would with a straight-edge blade. This allows for cleaner cuts with less tool vibration.
