Vincent CNC Core Drill Adapter – 10 mm to 1/2 Gas, with Grub Screw

The Vincent CNC Core Drill Adapter is a basic adapter with grub screw, 0.39 in. (10 mm) shank to 1/2 in. Gas.

Type: Basic adapter with grub screw, 0.39 in. (10 mm) shank to 1/2 in. gas
Fitting: 1/2 in. Gas

An adapter carries no diamond, so Vincent publishes no spindle speed, feed rate or stock removal for it. The parameters come from the tool it holds.

Key Features

• Converts to the 1/2 in. Gas fitting that Vincent's CNC range and most CNC tool holders use.
• Supplied with its screws — the part that is always missing when a wheel arrives without one.
• Listed by Vincent as a separate line item, which is why a wheel ordered on its own may not include it.

Who Is This For

Anyone fitting a Vincent tool whose own fitting does not match the spindle — most often a bore-mounted wheel going onto a 1/2 in. Gas holder.

It is not a consumable and does not affect the cut. If a tool is chattering, the adapter is worth checking for runout, but it is not the reason a wheel stops cutting.

Check what you are ordering: the diamond wheel and the fitting are separate part numbers in Vincent's catalogue, so a wheel ordered alone arrives without one.

Frequently Asked Questions

Does this include the diamond wheel?
No. Vincent lists the diamond wheel and the fitting as separate part numbers; this is the fitting.

Are the screws included?
Yes — Vincent lists this part as the fitting with screws.

What speed do I run it at?
An adapter has no parameters of its own. Run whatever the tool it holds is rated for.
