Lisle81780 Carbide Scraper Set

These work great for removing old RTV gasket maker. Just be mindful with aluminum as it will gouge if you put too much pressure or accidentally lift one side.

High quality and should have spent the money years ago

This carbide scraper works awesome, it’s my new favorite for cleaning any sealing surface from engine blocks to timing covers it works way better than a razor blade.

Easy to use on flat machined surfaces. Just be careful on soft aluminum.

I bought this set because I had heard good things about them when it came to removing old gasket material. I was working on a 1972 Honda CB500/4, and the side cover and head gaskets were near impossible to remove. I used a combination of brake cleaner, WD-40 and aircraft remover to loosen them up, and these to scrape down the gasket until it could be scraped off completely - you're not going to just be able to scrape the old gasket away, you have to work at it a bit, but I would say that when used in conjunction with the above liquids and an X-Acto knife, these scrapers DID shorten the job. They ARE very sharp though, and you have to let the tool do the work lest you gouge the aluminum - but you'll get the hang of it. Definitely worth having in the tool chest.

Goog product..Used to clean head gasket material off Caterpillar block...

I was trying to clean the thermostat and water pump mating surfaces from an older 1991 Jeep Wrangler. Needless to say, the gasket and antifreeze deposits were like built on metal and very difficult to scrape off. I used chemical gasket removers, acetone, wire brush and 3M green scrubber. I started to use a rotary tool, but stopped quickly as it can quickly remove metal and damage your surface. I decided to invest is these tools and they are perfect. You need both sizes to work different areas to minimize accidental damage because of bad angles or space constraints. These tools will scrape away those hard deposits, gaskets, etc leaving a nice smooth and flat surface. Take your time and don't rush and you will have a great surface to work with. I liked the handles quite a bit. Thick enough to fit comfortably in your hands. The product needs a case. There are covers for the blades, but no one would complain to have case. I bought a cheap case from Harbor Freight. The case had two permanent plastic partitions that I had to cut away using a dremel wheel. But the case fit perfectly.

these have their place, always pull these never push
