Product Information
Full details
The NTI 2.5 Inch Tungsten Carbide Scraper is a heavy-duty surface preparation tool designed for contractors, DIY renovators, and woodworkers who need to remove paint, varnish, and stubborn residues quickly. Its primary strength lies in its long-lasting, reversible tungsten carbide blade, which drastically reduces the frequency of sharpening compared to standard steel scrapers, though its rigid construction may require extra caution to avoid gouging softer wood surfaces during heavy-duty stripping.

FAQs
Can I sharpen the tungsten carbide blade?
Tungsten carbide is extremely hard and typically requires diamond sharpening stones or professional equipment; however, the blade is reversible, giving you two edges before replacement is necessary.
Is this tool safe for use on softwoods?
Yes, but use caution. Due to the hardness of the carbide, it can easily gouge soft woods like pine if used with excessive force.
Does the scraper work on metal surfaces?
Yes, the tungsten carbide blade is durable enough to scrape paint and rust off metal surfaces without sustaining damage.
How do I replace the blade?
Loosen the securing screws on the head of the tool, slide out the old blade, and insert the new or reversed blade into the slot before retightening.
Can this be used for wallpaper removal?
While it can remove stubborn wallpaper backing, it is better suited for paint, varnish, and heavy residue removal.
Troubleshooting
Blade chatter or bouncing during use
Adjust your pulling angle; ensure the blade is held firmly flat against the substrate.
Visible scratches left on wood
Reduce downward pressure and ensure no debris is trapped under the blade edge.
Blade slips during operation
Check the tightening mechanism to ensure the blade is fully locked into the housing.

Setup, Compatibility & Care
To begin using the NTI scraper, ensure the blade is securely fastened according to the manufacturer's mounting mechanism. No specialized assembly is required beyond confirming the blade is flush against the seating area. To maintain the tool, wipe the blade clean of resin and paint buildup after every use using a solvent-compatible rag. Store the tool in a dry environment to prevent corrosion of the handle fasteners. When the cutting edge becomes dull after heavy use, simply unfasten the blade, rotate it 180 degrees to the unused edge, and reinstall it securely.
