Diamond Finger Bits for Stone
Finger bits for cut-outs and truing saw lines
When a sink cut-out lands a couple of millimetres out, the fix is a side-cutting bit rather than a new slab. Item IDs SA25DFB-SA60DFB are hot-press sintered for a long working edge.
What Diamond Finger Bits for Stone Is For
The plant specification sheet describes this tool as used for grinding the holes or truing up saw lines of natural stone and artificial stone. That is exactly where it belongs, and where it stops.
The specification table lists 7 sizes, Item IDs SA25DFB to SA60DFB.
Diamond Finger Bits for Stone is the whole of the Diamond Finger Bits 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.
