Vincent T40 R3 Eased Edge Epic CNC Profile Wheel – Position 2 Medium, 120 mm

The Vincent T40 R3 Eased Edge Epic CNC Profile Wheel is a 4.72 in. (120 mm) position 2 medium metal-bond profiling wheel for shaping a CNC edge on granite, engineered stone and natural quartzite.

Spindle speed: 4,800–5,500 RPM
Feed rate: up to 374 in./min (9,500 mm/min)
Stock removal: up to 0.008 in. (0.2 mm)

Diameter: 4.72 in. (120 mm) · Height: 2.17 in. (55 mm) · Bore: 1.38 in. (35 mm)

Key Features

• Position 2 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.
• EPIC HS3 metal bond. Vincent publishes up to 374 in./min (9,500 mm/min) for this position against 197 in./min (5,000 mm/min) for its standard slotted wheel — roughly twice the feed rate for the same cut, which is where the cycle time comes from.
• 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: 4.72 in. (120 mm) diameter, 2.17 in. (55 mm) working height, 1.38 in. (35 mm) bore. 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 T40 R3 edges on a CNC and running them in volume. At up to 374 in./min (9,500 mm/min) this is a wheel built for unattended cycles and production throughput rather than one-off work.

It is not a polisher. Position 2 leaves a ground surface by design; the gloss comes from the position 4–6 resin polishers in the same T40 R3 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 2?
Vincent publishes up to 374 in./min (9,500 mm/min) at 4,800–5,500 RPM for a position 2 profiling wheel of this type, with stock removal up to 0.008 in. (0.2 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.

What bore does it need?
1.38 in. (35 mm). That is the standard Vincent profile-wheel spindle fitting for this range.

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.
