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.
