Fast, clean dry drilling across a wide range of ultra-hard stone materials. Weha Dry Magic Vacuum Brazed Core Bits are purpose-built for fabricators and installers who need speed, durability, and versatility on the job. Available in 10 diameters from 1/4" (6mm) to 2" (50mm), these vacuum-brazed core bits deliver aggressive cutting performance with long working life — particularly effective on sintered and ultra-compact surfaces like Dekton and Lapitec where standard core bits struggle. Available Sizes 1/4" (6mm) 3/8" (10mm) 1/2" (12mm) 3/4" (20mm) 1" (25mm) 1-1/4" (32mm) 1-3/8" (35mm) 1-1/2" (40mm) 1-3/4" (45mm) 2" (50mm) Vacuum Brazed Technology The vacuum brazed diamond matrix keeps diamonds fully exposed throughout the life of the bit — delivering superior cutting speed compared to traditional electroplated core bits. Fully exposed diamonds improve drilling efficiency and reduce heat buildup during dry use, making these bits particularly effective on hard, brittle sintered stone surfaces where heat management is critical. Compatible Materials Granite (light & dark) Marble Dekton, Lapitec, Neolith, and other sintered stone Ultra-compact surfaces Engineered stone and quartz Applications Faucet holes and plumbing cutouts Anchor holes Jobsite modifications and field drilling Shop fabrication drilling Dry Magic vs. Blitz — Which Core Bit Do You Need?
