Description
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?
- Dry Magic Vacuum Brazed (this product) — 10 sizes from 1/4" to 2"; optimized for sintered stone, Dekton, Lapitec, and ultra-compact surfaces; vacuum brazed for heat management on brittle materials
- Blitz Dry Diamond Core Bit — 1-3/8" and 2" only; interior & exterior vacuum-brazed diamonds; 60–150 hole life; optimized for granite, quartz, and marble at high RPM
- Dry Magic Hex Head Core Bits — hex shank for drill driver use; no grinder required
Key Features
- Vacuum brazed diamond bond — fully exposed diamonds for maximum cutting speed and heat reduction
- 10 sizes available — 1/4" (6mm) through 2" (50mm) for all standard drilling applications
- Sintered stone optimized — effective on Dekton, Lapitec, and ultra-compact surfaces
- Minimizes chipping — controlled cutting action on brittle materials
- Dry use — no water required; ideal for jobsite and field drilling
Works Well With
- Weha Blitz Dry Diamond Core Bit — high-speed alternative for granite and quartz with interior & exterior vacuum-brazed diamonds
- Weha Dry Magic Hex Head Core Bits — hex shank version for drill driver use without a grinder
- Weha T-31 Anchor Bit — for drilling anchor holes after core drilling is complete
- Weha Ceramica R-Mesh Turbo Blade — for cutting the same Dekton, Lapitec, and sintered stone materials
- Weha Rock Dog Router — for edge profiling on the same sintered and engineered stone after drilling
