1-3/16″ round x 2″ depth tialn cutter bits
TIALN COATED: Titanium Aluminum Nitride ( TIALN) is a thin film coating that was developed from Titanium Nitride. TIALN offers higher temperature resistance than TIN, as well as slightly higher hardness and especially higher hot hardness. This coating works by forming a thin surface layer of Alumina ( AL203), or Aluminum Oxide ceramic. As the layer wears it continuously reforms.
– Is harder than carbide and chrome on the Rockwell C scale
– Is dense and non-porous
– Tools typically last 3-10 times longer than uncoated tools.
Use this coated tool for longer tool life or for cutting harder materials such as stainless steel, harden steel, etc. Does not require very much lubricate, in fact, the hotter the material is processed, the better the coated tools work.
M2 High Speed Steel:
- Hardened & Precision Ground
- 3/4″ Weldon Type Flat Shank
- Traditional V & Flat Dual tooth Design
- Pilot Pin comes with each cutter and is included in the price
What is the purpose of coated cutters, or cutters made from premium steel?
Cutters made from M2 high-speed steel (HSS) are recommended for materials with a Brinell hardness number (BHN) of up to 275. A titanium aluminum nitride (TIALN) or similar coating may be applied to M2 to fortify wear resistance in materials up to 325 BHN. For materials up to 350 BHN, cobalt steel (M42) is recommended with a titanium nitride or similar coating.
