Vincent Gold CNC Finger Bit – 23 x 50 mm, 1/2 Gas

The Vincent Gold CNC Finger Bit is a 0.91 in. (23 mm) CNC shaft milling cutter — a finger bit for cutting sink and cooktop openings and inside radii on a CNC.

Diameter: 0.91 in. (23 mm) · Diamond length: 1.97 in. (50 mm) · Fitting: 1/2 in. Gas · Colour grade: Gold — engineered stone — quartz

No spindle speed or feed rate is published here. This part number appears in neither the 2026-I Vincent catalogue nor the current Vincent price list, so there is no manufacturer row to read the parameters from, and the figures published for the catalogue's other finger bits belong to different part numbers. The dimensions above come from the product title.

Key Features

• Gold in Vincent's colour system means engineered stone — quartz. It is the grade Vincent's distributors list for engineered stone, which is quartz surfaces in the customer's words. The colour code is Vincent-specific: the same colours mean different things on other manufacturers' bits, so do not read it across brands.
• 1/2 in. Gas fitting, so it runs in the same holders as the rest of the Vincent 1/2 in. Gas range.
• Flagged for review: no Vincent-published machining parameters could be tied to this part number, so none are printed.

Who Is This For

A fabricator matching bit grade to material rather than running one bit on everything — which is the whole point of a colour-coded range.

It is not a drill and not a profiling tool. A finger bit cuts on its side; plunging it loads the end face, where the diamond is not meant to work.

Do not program it from another bit's numbers. Vincent publishes different speeds and feeds for each grade and length in this range, and this part number is not in the current tables.
