4 flute solid carbide roughing mill with a TiSiN coating giving it a capability to cut materials up to HRC55. This mill is primarily used for edge or peripheral milling at high feed rate and chip clearance. A flute end mill will be required to cut your material with a finish
I highly recommend this bit, I've used in wood and it leaves a clean cut and is very quiet compared to HSS the same size
The 14mm roughing end mill I got is perfect for ripping metal off edges of blocks. On my relatively small 240V machine vibration and time required on task is greatly reduced. These cost a bit more than normal mills but are good value.
