The WILLIAMS COMFORT PRODUCTS 850-1 is a 2-inch wavy replacement blade designed for use with the 650 and 665 scraper models. The wavy blade profile is engineered to improve surface contact and material removal efficiency during scraping tasks. At 0.026 pounds, it is a lightweight consumable component intended for routine replacement in professional scraping applications. Licensed tradespeople and maintenance technicians working in facility maintenance, HVAC service, and general mechanical trades rely on this type of blade for clean material removal from flat and irregular surfaces.
This replacement blade fits the 650 and 665 scraper handles and is sold individually. It is suited for professional use in trade environments where scraper blades are regularly rotated or replaced as part of routine tool maintenance. The wavy edge design makes it particularly effective when working on surfaces where a standard straight blade may skip or chatter, providing more consistent cutting contact across the blade width.
Designed as a direct replacement blade for the 650 and 665 scraper models.
Blade replacement on hand scrapers is a straightforward task performed by maintenance and trade technicians. Always ensure the scraper handle is free of debris and the blade retention hardware is not worn before installing a new blade. Use appropriate personal protective equipment, including cut-resistant gloves, when handling bare scraper blades. Dispose of used blades in a puncture-resistant container in accordance with local safety regulations.
