THE HI-HELIX ANGLE reduces Tool Deflection by transferring stress vertically NOT
horizontally. This allow the End Mill to produce vertical Chip Ejection. CGS'
End Mills are 100% CNC Ground.
THE HI-HELIX ANGLE creates a greater Shearing Action, resulting in increased speeds and feeds, and
greater stock removal. Horsepower consumption is decreased while Radial-Side chip control on the cutting
flutes is eliminated, thus generating better chip control and surface finish.
Inherent to the manufacturing of HI-HELIX END MILLS is an extra heavy
core at the center of the End Mill. The
benefits of a large diameter core is that maximum tool rigidity is
obtained, which decreases tool deflection and chatter.
