CoroMill® 327
Designed for holes over 12 mm (.472 inch), Coro-
Mill 327 offers inserts for metric, UN and Whitworth
threads. The front-mounted inserts are positioned in
grooves for secure mounting, and through-tool coolant
aids chip evacuation, giving secure and continuous
performance.
CoroMill 327 is available in versatile grade GC1025,
for all material types.
Weldon shank
Use CoroMill 327 with steel or solid carbide shanks, available in
four diameters, and in overhangs from 74 – 160 mm
(2.193 – 6.3 inch).
• Steel shanks - for general machining,
when milling conditions are good
• Solid carbide shanks - provide lower
defl ection, enabling longer overhangs
and tougher machining with minimized
vibration.
