The 20mm Diamond Core Bit is the professional’s choice for installations requiring slightly wider clearances. Designed with a high-density diamond-bonded edge, it offers the strength needed to penetrate the hardest natural stones without the vibration or wandering common in lower-quality bits. This tool is essential for ensuring that holes for plumbing, electrical conduits, or heavy-duty anchors are cut cleanly and accurately.
Constructed for both durability and speed, this bit minimizes the risk of thermal stress or cracking on expensive stone slabs. The 20mm diameter provides that extra bit of space needed for easier pipe threading and adjustment. Whether working on a kitchen countertop or a full stone-tiled bathroom, this core bit delivers the precision and reliability required for a seamless, high-end finish.
