Using a hand drill is sometimes considered easier than CNC or ADU, because the device itself is less technical. However, alignment, feed, and speed control can make hand drilling inconsistent and error prone, even when you're using a drill jig or guide bushing. For hand drilling applications, AMAMCO designs features into the cutting tool to accommodate these elements.
- an adjustment in point geometries can allow for more control in the drilling process
- a double step angle on a reaming step can give you a smoother transition to the finished diameter
- reducing flute helix can minimize the force needed to penetrate the material, making the process more ergonomic
