DLC & TiSiN Coated Inner-R Corner Rounding End Mills
Questo 4-flute solid carbide inner-R corner rounding end mill features a precision-ground concave cutting profile for consistent external edge radiusing. DLC coating is suited to aluminum and selected non-ferrous metals, while Rivestimento in TiSiN supports steel and hardened-steel applications. Cutting geometry and coating are selected according to the workpiece material and finishing requirements.
DLC vs. TiSiN Coating Options
Select the coating according to the workpiece material and machining conditions.
DLC Coating — Aluminum
Low-adhesion coating helps reduce material buildup and supports smooth corner rounding in aluminum and suitable non-ferrous metals.
Ideale per: Aluminum alloys and selected non-ferrous materials.
TiSiN Coating — Steel
Wear-resistant coating supports stable edge radiusing in steel and selected hardened-steel applications.
Ideale per: Alloy steel, mold steel and suitable hardened steel.
Coating and cutting-edge geometry are application-specific. Confirm the selected configuration before ordering.
