descriptionSolid tungsten carbid under cut type drill series UC,Features a spade shape and outstanding from other competitors by the following charateristics:
Special designde diamter-cutting length ratio,thus minimized flection of the drill.
The margins are maintained only over a short length while the rest is reliefground,thus considerably reduces the friction,hence with less heat build-up and smear.
The transition from OD to the relief-ground section has been carefully made,thus prevent wall damage during the rapid return stroke.
