Scientific Cutting Tools AS5202-04XA | 0.4375-20 UNJF-3B Thread x 0.500" Shank x 2.750" OAL 3 Flute AlTiN Coated Carbide Tipped Pilotless Porting Tool

Description

The Scientific Cutting Tools AS5202-04XA porting tool is made for precision threading and porting in aerospace and high-performance engine components. It features a 0.4375-20 UNJF-3B thread form optimized for UNJF specification threaded holes. The carbide-tipped construction provides exceptional wear resistance and long cutting life in production runs. An AlTiN coating improves thermal stability and reduces flank wear during elevated-temperature cycles. With a 0.500" shank, the tool offers secure clamping and compatibility with common toolholders. The 2.750" overall length balances reach and rigidity for access to confined port geometries. Its 3-flute AlTiN-coated pilotless porting cutter geometry promotes uniform chip evacuation and consistent surface finishes. Pilotless design removes the need for a separate pilot drill, streamlining setup for threaded holes and ports. Carbide tipping enables higher feed rates while maintaining thread accuracy in difficult-to-machine alloys. The AS5202-04XA is made for aerospace/engine applications where UNJF-3B thread accuracy and repeatability are critical. Precision-ground flutes deliver stable cutting action and reduced vibration in interrupted cuts. This high-performance AlTiN porting cutter minimizes rework by producing clean threads with low burr formation. Use with appropriate coolant and recommended spindle speeds for optimal life when machining stainless steels and nickel-based alloys. The compact profile supports access in restricted assemblies without sacrificing bending strength. Manufactured to rigorous tolerances, the Scientific Cutting Tools AS5202-04XA provides reliable, repeatable results in demanding metalworking environments.
