💡 How does negative rake geometry improve finish quality on round wood lathe tool holders?
Understanding insertion angles matters because the cutter direction determines chip flow.
- negative clearance reduces resistance when planing dense timber stocks
- 30 degree wedge design breaks chips cleanly for smoother sanding jobs
- solid carbide core holds its sharpness through repeated grinding cycles
- exact 12 millimeter width slots perfectly into standard groove blocks easily
