Diamax Cyclone 1-3/8 in. Core Bit – Vacuum Brazed for Marble
Diamax Cyclone 1-3/8 in. Core Bit – Vacuum Brazed for Marble
The Diamax Cyclone 1-3/8 in. Core Bit is a 1-3/8 in. vacuum brazed core bit for drilling marble.
Vacuum brazing bonds diamond directly to the steel rather than sintering it into a segment, which is the right construction for soft stone: it stays sharp where a sintered segment would load up and polish.
Key Features
- 1-3/8 in. coring diameter
- Vacuum brazed diamond, not a sintered segment
- Bonded for marble
Not Recommended For
Not the bit for granite or quartz — brazed diamond wears off quickly in hard stone. Use the same diameter in a sintered-segment bit for those: the Diamax Cyclone Dry/Wet Turbo Core Bit – 1-3/8 in., for Granite & Quartz.
Who Is This For?
Fabricators drilling marble, where a sintered bit polishes instead of cutting.
Frequently Asked Questions
What does vacuum brazed mean?
The diamond is brazed straight onto the steel in a single layer instead of being sintered into a segment. It stays aggressive in soft stone.
What is it for?
Drilling marble with a vacuum brazed coring bit.
Can I use it on granite?
It is the wrong bit — brazed diamond strips quickly in hard stone. Use the Diamax Cyclone Dry/Wet Turbo Core Bit – 1-3/8 in., for Granite & Quartz.
