Sorby Excelsior TiN unhandled Bowl Gouge 3/8" (10mm)
Description
Robert Sorby Code B842G100
Excelsior 3/8 inch Unhandled Bowl Gouge
The Robert Sorby range has been designed with the connoisseur woodturner and those who regularly turn hardwoods in mind. A plasma bonded titanium nitride finish layered over traditional triple tempered high-speed steel provides longevity and edge retention.
The Titanium Nitride coating increases performance and resistance to edge wear. The cutting edge on these tools will outlast the normal Sorby HSS tools by a minimum of three fold. Spend less time sharpening and more time turning.
3/8 inch or 9.5mm between the tips of the flute (often called a 10mm Bowl Gouge)
Chisel shaft is 13mm diameter
A traditional radial grind (an English grind) of 45 degrees.
Regrind to your preferred angle or fingernail shape.
Titanium Nitride (TiN) plasma bonded coating:
* TiN is bonded onto quality High Speed Steel. It provides the same advantages as HSS whilst enhancing the cutting life close to that of Tungsten Carbide.
* Uses the same traditional sharpening equipment as used for HSS
* Sharpens to 0.15-0.2 microns - HSS is 0.2-0.4 Microns, Carbide is 0.7 Microns (smaller is sharper)
* Hardness of coating; up to 85RC (HSS is 62RC. Tungsten is 90RC)
Note, when you grind a Nitride coated chisel you grind the bevel which moves the cutting edge slightly up the flute providing a fresh edge of Nitride coating on the cutting surface.
Note: fits Sovereign Handle.
