Overview

Excelsior cutters are manufactured from a combination of materials: a highspeed steel core for the sharpest possible edge and finest finish, and a titaniumnitridecoating which helps it rival carbide in terms of edge retention. Unlikecarbide, however, these turning tool cutters are easily sharpened on standardsharpening equipment. Available in a range of profiles to fit almost any turningapplication. Cutters for the TurnMaster system are also available in TungstenCarbide and standard HSS (e.g. 49356 and 49956, sold separately). See the"More Info" tab for more on the different cutter materials.

Technical Details:
  • Hybrid "Excelsior" material combines the fine finishing qualities of HSS with atitanium-nitride coating that helps it rival carbide in durability.
  • Coating does not "wear off". Instead, with each sharpening, a fresh, coatededge is exposed.
  • Cutters can easily be swapped by removing the high tensile torx screw on theTurnMaster shank.
  • Round Excelsior Cutter is 9/16" in diameter, and is ideal for waste removal andshaping of concave surfaces.
  • Square Excelsior Cutter measures 9/16" x 9/16", and is ideal for waste removaland shaping of flat and convex surfaces.
  • Detail Point Excelsior Cutter measures 1/2"W x 1-3/32"L, and is used for partingand line detailing.
  • French Curve/Inside Excelsior Cutter is used for shaping and finishing ofinternal/concave surfaces.
  • Box/Detail Excelsior Cutter has parallel side walls, which are perfect for makingboxes and dovetails.
  • Teardrop/Inside/Outside Excelsior Cutter is ideal for scraping and shearscraping of both concave and convex surfaces.
  • Mushroom Excelsior Cutter is used for undercutting small hollow forms.

Which cutter material should I use?
Cutters for the Robert Sorby TurnMaster are available in Tungsten Carbide, HighSpeed Steel (HSS) and HSS coated with Titanium Nitride ("Excelsior").

Tungsten Carbide:
  • Designed to be disposable, these carbide cutters don't require any sharpening.
  • (Carbide tips can be sharpened, but require specialized diamond abrasives).
  • Carbide stays reasonably sharp for a longer period of time, but because of itscoarse grain, can never be sharpened as finely as HSS.
  • Gives extended cutting life with the toughest of woods.
  • Sharpens to 0.7 - 1 microns.
  • Hardness: 90 RC.
  • Material: micro grade tungsten carbide.

High Speed Steel (HSS):
  • Due to its finer grain structure, HSS holds a sharper edge than carbide, but willdull more quickly.
  • Very economical - can be re-sharpened multiple times with standardsharpening equipment.
  • Provides unmatched quality for the discerning woodturner keen on gettingthe greatest detail from their tools.
  • Sharpens to 0.2 - 0.4 microns.
  • Hardness : 62 RC.
  • Material: M2 HSS.

Titanium Nitride-Coated HSS (Excelsior):
  • These cutters provide the same advantages as HSS but give added longevitybefore sharpening is required.
  • Sharpens to 0.15 - 0.2 microns.
  • Hardness of titanium coating is up to 85 RC.
  • Material: Titanium nitride coated M2 HSS.
