Taper bore style is the most reliable and accurate locking in tool manufacturing. Most of the spindles for CNC machine, lathes, drill machines, routers are made with taper bores. For our spiral cutterheads, the screw taper fits into the taper of the carbide insert, which can precisely lock the inserts in the seats of the cutter block. The carbide inserts with taper bore are the most popular style of cutterheads. These standard-size carbide insearts can be easily purchased online at low cost in the future.
