What tool coatings do you offer?


GARR TOOL offers a variety of different tool coatings, available on certain catalog items. Some coatings can be added to stock items. If a particular coating is not available by either of those options, you can request a quote.

TiN Coated TiN (Titanium Nitride)
General purpose coating – low heat resistance. Good lubricity.
TiCN Coated TiCN (Titanium Carbonitride)
Good abrasion resistance. Recommended for aluminum, brass, and bronze applications. Low heat resistance – good lubricity.
TiAlN Coated TiAlN (Titanium Aluminum Nitride)
Multi-layer coating with good thermal stability for increased speeds and feeds. For semi-dry to dry cutting of most steels, high-nickel alloys, stainless steel and cast iron. Excellent heat resistance, good lubricity. For materials that are 40Rc and under.
AlTiN Coated AlTiN (Aluminum Titanium)
A single-layer coating whose hardness, oxidation resistance and thermal stability were optimized for material hardness above 38Rc and high-speed machining of materials that are difficult to work (titanium alloys, Inconel).
TiB2 Coated ALUMASTAR® (Titanium Diboride – TiB2)
A thin film coating with a low affinity for aluminum, ideal for machining aluminum alloys. The resistance to adhesion of aluminum allows higher speeds or feeds. Coating thickness is intentionally kept lower in order to maintain a sharp edge.
Improved productivity in composites. Excellent choice for cutting graphite and fiberglass. Can be added to a special for milling or drilling applications.
AlCrN Coated AlCrN (Aluminum Chromium)
Aluminum Chromium-based coatings have excellent wear resistance, thermal shock stability, and hot hardness. Well suited for Titanium, Inconel, and carbon fiber.
Multi-layer coating with thermal stability and lubricating properties needed for the drilling of steels, high-nickel alloys, stainless steel, cast iron, aluminum, brass, and bronze. Excellent heat resistance, great lubricity.
AlTiN Coated AlTiN-based
Greater abrasion resistance, extra shear strength, lower adhesion tendency, maximum toughness and a very smooth surface achieve a quantum leap in drilling performance. This coating is particularly advantageous for carbide drills. With its unique nanostructure, AlTiN plus AlCrN, it boosts productivity in various materials.
AlCrN-based Coated AlCrN-based
High wear resistance even under severe thermal stress. Revolutionary smooth coating with outstanding adhesion. Prevents sticking and build-up on edges. Precise high-performance coating. Maintains sharp edges. Primarily for high-temp alloys, stainless, and tool steels.
