13-Inch Spline Shank Bit
The ARTU 02020 is a 1/2-inch diameter drill bit with a 13-inch overall length. It uses a spline shank for positive drive in heavy-duty rotary hammers. The two-cutter head geometry is intended for drilling concrete and masonry.
Spline Lock and Deep Reach
The spline connection prevents the bit from slipping under high torque, a practical advantage when drilling deep holes in hard aggregate. The 13-inch length allows access through thick walls or flooring without needing an extension. The two-cutter design clears dust efficiently during continuous drilling.
Replaces Worn Two-Cutter Bits
This bit replaces a worn or damaged two-cutter spline shank bit of the same diameter and length. The upgrade is justified when the old bit no longer cuts straight or its shank engagement has become loose. It is not suited for users who require a four-cutter head for reinforced concrete or a different shank system such as SDS-max.
