Description
- 15º spiral flutes for improved chip removal
- More flutes than Type 374 for use where less feed per tooth is required, but table speed is maintained for same productivity
- Spiral flutes distribute the impact load evenly, improving finish and increasing tool life.
- Radial edged for longer tool life
- Geometry and carbide grade, O.D. relief and end clearance appropriate for material being machined
- Flute long carbide tips brazed to tough hardened alloy steel body
- Spiral flute carbide tips formed to true helix angles
- Straight shanks have standard Weldon drive flats
- Non-center cutting end mills have the ends cleared to depth of carbide
Modifications
- Modified tool diameter
- Metric tool diameter
- Cutting diameter reduced for step or pilot
- Corner chamfer or corner radius
- Shortened shank or reduced shank diameter
- Additional shank drive flat(s)
- Coolant outlets
- Stocked coated tools priced below
Coatings available:
- TITANIUM NITRIDE - TiN
- TITANIUM CARBONITRIDE - TiCN
