Vincent Z50 CNC Peripheral Wheel – Position 3 Fine, 1/2 Gas Fitting, 20 mm Diameter

The Vincent Z50 1/2 in. Gas CNC profile wheel is a 0.79 in. (20 mm) position 3 fine metal-bond profiling wheel for shaping a CNC edge on granite, engineered stone and natural quartzite.

Spindle speed: 8,000 RPM
Feed rate: 31–59 in./min (800–1,500 mm/min)
Stock removal: up to 0.004 in. (0.1 mm)

Diameter: 0.79 in. (20 mm) · Fitting: 1/2 in. Gas

Key Features

• Position 3 of Vincent's 0–6 set. Positions 0–3 are metal bond and take the edge to shape; positions 4–6 are resin and take it to gloss.
• Vincent publishes 31–59 in./min (800–1,500 mm/min) at 8,000 RPM for this position, with stock removal up to 0.004 in. (0.1 mm).
• The softer bond releases spent diamond as it wears instead of polishing over, so the wheel keeps cutting without glazing on dense material such as quartzite and porcelain.
• Fitment: 0.79 in. (20 mm) diameter, 1/2 in. Gas fitting. Vincent sizes its resin polishers to match the metals in the same set, so positions swap without re-setting the tool length.

Who Is This For

A high-production shop programming Z50 edges on a CNC and running them in volume. At 31–59 in./min (800–1,500 mm/min) this is a wheel built for unattended cycles and production throughput rather than one-off work.

It is not a polisher. Position 3 leaves a ground surface by design; the gloss comes from the position 4–6 resin polishers in the same Z50 set. Do not try to close the surface by slowing this wheel down — that glazes the bond and shortens its life.

Vincent lists this wheel for granite, engineered stone and natural quartzite. For technical ceramics and Dekton it publishes a separate CERAM range; running a granite bond on ceramic slab is the usual cause of chipping at entry and exit.

Frequently Asked Questions

What feed rate and spindle speed should I run at position 3?
Vincent publishes 31–59 in./min (800–1,500 mm/min) at 8,000 RPM for a position 3 profiling wheel of this type, with stock removal up to 0.004 in. (0.1 mm). Those are the manufacturer's figures for the position, not a shop rule of thumb.

Will it polish the edge?
No — positions 0–3 are metal bond. They cut the profile; the resin positions 4–6 polish it. Expect a ground surface off this wheel.

Will it hold up on quartzite and porcelain?
That is what the softer bond is for: it releases spent diamond rather than glazing, so the wheel keeps cutting on hard material. Vincent lists the range for granite, engineered stone and natural quartzite.

How does it mount?
On a 1/2 in. Gas tool holder — the small-wheel fitting Vincent uses so the tool can reach inner bores and blind spots as well as outside edges.

Is "engineered stone" the same as quartz?
Yes — engineered stone is Vincent's catalogue wording for quartz surfaces such as Caesarstone, Silestone and Cambria. The wheel is listed for them.
