• [Patented TR Processing] Triangle-shaped threads with low friction speed up insertion compared to conventional course threads.
• Since the chips are stored in the vertical rollers, the expansion of the wood is prevented and the wood cracking is reduced.
• Low friction load, low torque and long battery life.
• The special tip cutting process allows for smooth entry of hardwood.
• For woodworking.
• For hardwood or inner wear.
