SPLINE JET-HEAD Concrete & Masonry Drill Bits – Made in Germany
Built for demanding concrete and masonry drilling, these German-made SPLINE JET-HEAD drill bits combine a rugged quad-carbide cutting head with a heavy-duty SPLINE shank for professional rotary hammer applications.
The advanced JET-HEAD carbide design provides fast, smooth drilling with reduced vibration, while the center point helps the bit start accurately on hard surfaces. A high-performance TWINMAX flute design quickly moves concrete dust and debris out of the hole for more efficient drilling.
