1-3/16" x 1" depth TIALN COATED HSS Annular Cutter

Description

HSS   M2  Steel TIALN COATED Annular Cutters - this listing is for :
(1)   1-3/16" diameter  x 1" depth of cut cutter
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
With their unique centerfree design,  annular cutters cut only the periphery of the hole, ejecting the remaining center as a slug. These cutters produce reamed quality, burr-free holes in one operation, eliminating costly pilot holes and step drilling. Our cutters reduce torque and horsepower requirements by only cutting the periphery of the hole using the proper tooth geometry.
