Lisle Carbide Scraper Set 5/8" & 1-1/4" — Tungsten-Carbide Tips, 6" Ergonomic Handles

The Lisle 81780 Carbide Scraper Set is a two-blade scraper kit with tungsten-carbide tips designed to remove gasket residue, carbon build-up, and light rust from steel and aluminum surfaces.

The Lisle 81780 offers two blade widths—5/8" and 1-1/4"—mounted into sturdy 6" handles so you can tackle tight passages and larger flat surfaces without changing tools. Each scraper features a precision-ground tungsten-carbide tip fixed to a steel blade that is molded into the ergonomic handle for control and durability. This set is made for automotive and mechanical cleanup tasks where metal-to-metal contact is required but you want a long-lasting cutting edge that stays sharp under repeated use.

How do these carbide scrapers remove old gaskets and carbon deposits?

The tungsten-carbide tips concentrate cutting power into a very hard edge that scrapes away residue without flexing like softer materials. Because the tip is ground to a sharp profile and bonded to a steel blade, it shaves away gasket material and carbon while resisting dulling from repeated scraping. They are intended for use on metal heads and manifolds where controlled scraping is needed.

• Precision-ground carbide tips maintain a sharp edge for longer life.
• Steel blades provide rigidity and support under forceful scraping.
• Two widths let you access narrow passages and larger flat areas.
• Molded 6" handles improve leverage and control during use.

Which surfaces and tasks are these scrapers best suited for?

The Lisle 81780 scrapers are intended for steel and aluminum surfaces such as cylinder heads, intake manifolds, and brake caliper slides. They handle baked-on carbon, gasket residue, and light surface rust where a sharp, hard edge is needed to remove material without excessive blade wear. They are not designed as a substitute for powered grinding on heavy corrosion.

• Cylinder heads and intake manifold flange cleanup.
• Removing gasket remainers and sealant from mating surfaces.
• Cleaning carbon deposits from ports and valve areas.
• Light rust and brake-caliper slide surface prep.

How are the scrapers constructed and how do they hold up over time?

Each scraper uses a tungsten-carbide tip attached to a steel blade that’s molded into a contoured 6" handle. Carbide is much harder than steel, so the tip resists dulling and will stay serviceable through many uses. If a tip becomes worn, Lisle offers the scrapers individually, making replacement or single-tool purchases possible without buying a whole new set.

• Carbide tips are precision ground for consistent cutting geometry.
• Steel blades give strength and support under scraping pressure.
• Molded handles reduce slippage and improve comfort during extended work.
• Individual availability lets you replace one scraper without replacing both.

Which scraper width should I use for specific jobs?

Choose the 5/8" blade when you need to access tight ports, passages, or around threaded holes. Use the 1-1/4" blade for broader, flat surfaces like manifold flanges or larger gasket areas. Both widths are included so you can switch between precision work and general surface cleanup without compromising effectiveness.

• 5/8" blade: narrow spaces, detailed scraping, port work.
• 1-1/4" blade: wider flanges, gasket faces, larger surfaces.
• Both together cover most common automotive cleanup tasks.

Who is this for: The Lisle 81780 Carbide Scraper Set is aimed at professional mechanics, home-garage enthusiasts, and technicians who need a durable, long-lasting hand scraper for removing gaskets, carbon, and light rust from metal parts. If you routinely service cylinder heads, intake manifolds, brake components, or any steel and aluminum mating surfaces, this set gives you two common blade widths and carbide durability in a compact, user-friendly package.
