Description
The 'Purple' line of tooling is designed specifically for cutting wrought titanium alloys.
The 'Pointer' line is a tight-tolerance 3D point/ball finishing tool which uses only the tip of the tool for cutting. This line is intended for machine tools with spindles capable of speeds up to 20K rpm.
'R' form tools are the classic end-mill shape, straight sides (flanks) with corners ranging from sharp (flat tip) to completely round (ball tip). This form is the most common of all, and good for almost everything.
