Vincent CNC Core Bit – 35 mm Diameter, 80 mm Length, 1/2 Gas Fitting, for Ceramic

The Vincent CNC core drill is a 1.38 in. (35 mm) CNC core drill for cutting faucet and fixture holes in technical ceramics and Dekton.

Spindle speed: 2,000 RPM
Feed rate: 1–1 in./min (27–35 mm/min)

Diameter: 1.38 in. (35 mm) · Diamond thickness: 0.04 in. (1 mm) · Fitting: 1/2 in. Gas

Drilling depth is not stated on this page. The title, the catalogue and the price list give three different lengths for this part; see the discrepancy note rather than assume one.

Key Features

• Vincent publishes 2,000 RPM at 1–1 in./min (27–35 mm/min) for a core drill of this diameter. Speed drops as diameter rises — the figure is per size, not one number for the range.
• Thin wall at 0.04 in. (1 mm). Less material to displace means less power at the rim and less chipping on the exit face.
• Vincent's instruction for ceramic slab and Dekton: proceed in 0.20 in. (5 mm) steps with a few seconds' pause between steps, and reduce speed entering and leaving the material. That is what stops the exit blow-out.
• 1/2 in. Gas fitting.

Who Is This For

A high-production shop drilling faucet holes on the CNC rather than by hand, where a consistent hole and a clean exit matter more than raw speed. Speed drops with diameter for a reason: rim velocity rises with size, and on dense material a rim run too fast glazes instead of cutting.

It is not a profiling or stubbing tool, and it is not for enlarging an existing hole — a core drill needs full rim contact to stay round. Use a finger bit to open out a hole that is already cut.

This is the ceramic and Dekton drill. On granite it will be slow and will glaze; Vincent lists separate universal, premium and long-life granite core drills.

Frequently Asked Questions

What speed should I drill at?
Vincent publishes 2,000 RPM at 1–1 in./min (27–35 mm/min) for this diameter.

How deep will it drill?
We have not printed a figure. Three sources give three different lengths for this part number, and the difference is between total tool length and usable drilling depth. It is flagged for review rather than guessed.

What does it fit?
A 1/2 in. Gas tool holder.
