Aimed at the discerning woodturner and those that regular turn hard woods the Robert Sorby Excelsior range incorporates titanium nitride (TiN) plasma bonded steel coating technology.
In tests the TiN coating outperforms the hardest wearing steel tools and will even better tungsten carbide, which can be chip. In terms of cutting edge life Robert Sorby Excelsior tools will outlast standard tools by four times and are more than a match for the various metallurgies available to today's woodturners.
The advanced TiN finish is applied in a thicker layer than was possible before. This ensures the Excelsior range performs at the highest levels of durability and unlike carbide, tools are still quick and easy to sharpen.
Coated on premium quality flawless high-speed steel (HSS), TiN also provides the added advantage of reducing friction for a smoother more refined cut. This is particularly effective when working with extremely hard and abrasive exotic woods, or cutting through knot-riddled burrs.
Edge retention and sharpening are the key assets to the Excelsior range. The hardness of woodturning tools, usually measuring in between 60 and 65 on a Rockwell scale, do not come close to the 3500 Brinell (the equivalent of 80 on the Rockwell scale) of the TiN range. Despite the hardness, the combination of TiN and traditional HSS ensure the Excelsior range retains its edge whilst keeping its toughness and eliminating the possibility of brittleness and chipping, which can be associated with more resistant metals.
The Robert Sorby Excelsior range is available in all hard working tool types including roughing gouges, bowls gouges and in the many versatile and popular Robert Sorby cutters on the market.
Features and Benefits:
1. Extended tool life
2. Cutting edges last up to four times longer
3. Titanium nitride (TiN) plasma coating â€“ outperforms cryogenic and powder metallurgy tools
4. TiN is a corrosion resistant ceramic coating
5. Friction coefficient helps chip flow, reducing the build up of material at the working edge
6. Quick and easy to sharpen
7. Edge retention second to none
8. The result - spend more time turning and less time sharpening
Prices: The range starts at £21.85 for a handled 6mm (1/4in) spindle gouge (inc VAT)
