+ Thanks to the small cutting load of the serrated cutting edge and helical
interpolation, low power consumption of the spindle is required.
+ Circular ramping milling, maximum ramping angle is 20°.
For example: tool HD27 machining Ø50 mm hole, 9 mm pitch for
aluminum, 6 mm pitch for carbon steel.

+ Cuts by helical interpolation.
+ Each holder can machine different diameters and hole depths.
Example:

+ Serrated cutting edge makes the chips short and small, and easier to evacuate.
+ Eliminate swarf and vibration problems while drilling diffcult or deep holes.

+ Not only a drill, but an end mill too.
+ Small radius path to cut a hole or step hole, various curved cavity shapes
on different materials.
