Product Description
JGZUI SDS Plus drill bits are built for rotary hammer work in concrete granite marble brick and block. The YG8C carbide tip is brazed to a hardened 40Cr chromium steel body that absorbs percussive impact and resists bending under load. The SDS Plus 4-slot shank fits standard SDS Plus rotary hammers. A two-cutter tip scores the material while the flute channels dust out of the hole so the bit stays cooler and cuts faster even at depth. Choose the diameter and length for your application. Shorter 110 mm and 160 mm bits work for electrical boxes cabinet hardware and anchor holes. Mid-length 210 mm and 260 mm bits handle framing walls and general construction. The 350 mm and 450 mm lengths reach through thick masonry and foundations. Bits are available with single or double flute designs. Single flute improves dust removal on deep holes while double flute balances speed and chip clearance on standard depth work. Each bit ships in a plastic case to protect the cutting tip. Use water cooling when drilling hard stone or engineered brick to extend bit life.
