The cemented-carbide blade is ideal for scraping on wood, metal, and concrete. It stays sharp and productive for up to 50 times longer than a regular steel blade. The blades are precision-ground with a slightly convex shape to prevent scratching the work surface. There are different sizes available, including the 442 double-edged blade with a length of 50 mm, the 451 double-edged blade with a length of 65 mm, and the 449 triangular blade with a length of 25 mm. The 442-3P set includes 3 blades of the 442 model. These blades are replacements for the 625, 650, and 665 scrapers. They are easily turnable and repositioned for different radii or angles.
