Item #
GRP32570
Rating:
100% of 100
Designed specifically to fit the Robert Sorby TurnMaster system, these carbide cutters offer excellent durability and all-around turning performance. The cutters are disposable, which eliminates the time and expense of sharpening. Available in three profiles: round, square and detail point (diamond). The same cutters are also available in HSS and Titanium-Nitride coated HSS (e.g. #49956 and #45438, sold separately).

Features:
  • Solid tungsten carbide for an incredibly long cutting life.
  • Cutters can easily be swapped by removing the high tensile torx screw on the TurnMaster shank.
  • be easily removed to change the cutter.vRound Carbide Cutter is 9/16" in diameter, and is ideal for waste removal and shaping of concave surfaces.
  • Square Carbide Cutter measures 9/16" x 9/16", and is ideal for waste removal and shaping of flat and convex surfaces.
  • Detail Point Carbide Cutter measures 1/2"W x 1-3/32"L, and is used for parting and line detailing.

Which cutter material should I use?
Cutters for the Robert Sorby TurnMaster are available in Tungsten Carbide, High Speed 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 its coarse 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 will dull more quickly.
  • Very economical - can be re-sharpened multiple times with standard sharpening equipment.
  • Provides unmatched quality for the discerning woodturner keen on getting the 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 longevity before sharpening is required.
  • No specialized equipment is required for sharpening.
  • Repeated sharpening does not remove the titanium nitride coating, it simply renews it.
  • Sharpens to 0.15 - 0.2 microns.
  • Hardness of titanium coating is up to 85 RC.
  • Material: Titanium nitride coated M2 HSS.

I like the convenience of not having to sharpen the tool every time I use it and during usage.

Because it is always handy to have a spare and it is carbide.

My son and I have been turning items from Alabaster blanks, and we've had good success using these Carbide Cutter inserts. They are easily sharpened using a diamond sharpening card held flat against the top circular cutting surface. If you try turning alabaster, use a powerful dust collector system and respirator.
