Robust, Nitrided HSS, 1" x 5/16" Large Negative Rake Scraper with Maple Handle

All Scrapers and Detail Gouges offered by Robust Tools are manufactured in the United States using premium high speed steel (HSS). Each tool is treated with a proprietary Nitriding process which results in significantly improved edge-holding and reduced sharpening.

After machining the tools to shape, they are heat-treated 62-64 Rockwell C. The hardened tools then go through the Nitriding process, increasing surface hardness to 1880 Vickers (75+ Rockwell C). Because the treatment is diffused into the metal itself, it will not flake, peel or chip. The tools are just as easy to grind as regular HSS and sharpen well on conventional and CBN wheels.

To sharpen your Robust Scraper, just grind the bottom bevel. This leaves the Nitriding on the top surface, so the burr is Nitrided.

Tool Width: 1" | Tool Thickness: 5/16" | Handle Length: 16" | Overall Length: 23"

Made from Nitrided M42 High Speed Steel

Scrapers will not produce a finish that is as good as a gouge, but are useful in many situations where cutting with a gouge would be difficult or a fine finish is not required. The bottom edges are radiused so that you can use it at an angle for even more effective cutting

Nitriding reduces surface friction, improves wear resistance and significantly enhances edge holding

All Robust Tool handles are hard rock Maple, turned to their specifications in Pennsylvania and feature stainless steel ferrules.

Robust combines skillful engineering and quality materials to produce premium woodturning lathes and accessories.
