Vacuum Brazed Diamond Core Bit
Dry core bits from 5 to 83 mm
Drilling through tile, then brick, then concrete normally means changing bits twice; a brazed bit goes through all three. Dia 5-83 mm with mesh sizes 30/40 and 40/45.

What Vacuum Brazed Diamond Core Bit Is For
The plant specification sheet describes this tool as used for fast and long-life drilling stone, concrete, brick, ceramic and other abrasive materials. That is exactly where it belongs, and where it stops.
Standard specification: Dia5-83mm , mesh size:30/40 40/45.
Vacuum Brazed Diamond Core Bit is the whole of the Brazed Core Bit category, so specification work happens inside the item rather than by picking between siblings.

Use Guide
Confirm the fit
Check diameter, bore and segment dimensions against the table above and against your machine.
Set the parameters
Start at the machine builder's figures for your material, then adjust feed until the cut runs quiet and the surface stays clean.
Keep it free-cutting
If the tool stops cutting and the face goes shiny, it has glazed. Dress it, then tell us — that means the bond should change.
