Long-Life Carbide Blade Flat-Surface Scrapers


Rubber Handle and Straight Blade with Knob	Plastic Handle and Triangular Blade	Plastic Handle and Straight Blade with Knob

Plastic Handle and Straight Blade	Rubber Handle and Triangular Blade

Made of carbide, the blades stay sharp longer than steel blades.

Rubber Handle—Scrapers with a rubber handle are more comfortable to grip and less likely to slip than scrapers with a plastic handle.

Knob—Scrapers with a knob are good for high-resistance applications that require you to use two hands.

Choose from a range of blade shapes to scrape burs from flat surfaces to tube edges. Insert blades with a 0.1" dia. shank into a changeable-blade deburring scraper. For blades without a shank, they require a blade holder (sold separately); they are only for use with adjustable-length deburring scrapers, which secure the blade holder.

Carbide Blade—Carbide blades are harder than steel and cobalt blades, stay sharp longer, and withstand higher temperatures. Use them for deburring tough materials, such as hardened steel.

Diamond-Coated Steel Blade—Diamond-coated steel blades are the toughest blades we offer. They are hard enough to deburr carbide and sharp enough to deburr hard nonmetals, such as glass.

Extra Long-Life Multipurpose Oscillating Tool Blades

Open

Mount

These blades have the longest life in our oscillating tool blade offering—they’ll stay sharp 100 times longer than bimetal blades with high-speed steel teeth. Use them to cut through wood, metal, plastic, and drywall without changing blades. Because of their size, they’re typically used for small jobs, such as making notches in sheet metal. These blades mount to your oscillating tool at any angle, so you can avoid awkward cutting angles and reach into tight spots.

Open Blade Mount—Since they’re open mount, they’re compatible with all non-Starlock tools.

Carbide Teeth—With teeth made of a specialized carbide blend, even hundreds of cuts through nail-filled wood won’t dull them down.

Black-Oxide Steel Body—They have a black oxide finish for mild corrosion resistance in dry environments.

Changeable-Blade Sheet Metal Deburring Scrapers

Swap out the blades on these scrapers to smooth sheet metal in different thicknesses. The V-shaped blades remove burs from both sides of an edge at the same time. Pull the collar down to change blades. You can also slide the blade holder in or out of the handle and lock it at any length you need.

Reciprocating Saw Blades for Grout

Attach these blades to your reciprocating saw to remove grout from between tiles. The saw moves them back and forth at high speeds to grind through grout faster than oscillating or rotary tools. They’re also coated with a tungsten carbide grit that cuts quickly and resists wear—it’s nearly as hard as diamond. These blades have a _1/2” universal shank that fits most reciprocating saws.

Deburring Scraper Drill Attachments for Pipe and Tube Edges

These drill attachments scrape both the inner and outer edges of plastic pipe and tube to finish them for connections. There’s a hex shank on each end—flip attachments around in your drill to switch from deburring inside edges to outside edges. Use in drills 14V and up.

Mount

No need to add a sanding sheet to your oscillating tool—these plates come with carbide abrasive already built in. Shaped for edges and corners, they’re often used in tight spaces. They work well for heavy material removal on small sanding jobs.

Starlock Mount—Starlock-mount plates can be used with any Starlock-compatible oscillating tool. Their vacuum holes let sanding dust escape during material removal so it doesn’t build up on the abrasive surface.

Open Mount—Open-mount plates have a universal mounting pattern for use with non-Starlock oscillating tools. Operate your oscillating tool at two-thirds its maximum speed when using one of these plates.
