About This Product
Segmented CNC Tooling for Porcelain & Sintered Slabs
Alpha CNC Finger Bits are designed for machine-controlled cutting in porcelain, sintered slabs, Dekton®, Neolith®, crystallized glass, and other vitreous materials. Their segmented construction gives fabrication professionals dedicated tooling for working with these hard, specialized surfaces.
Controlled Cutting with Reduced Blow-Out
The selected diamonds and matrix help minimize blow-out as the tool exits the material. Designed for compatible CNC machines and radial arm workstations, the 20mm-diameter tool supports controlled material removal during cutout and exterior cutting applications.
Two Lengths with a 1/2" Gas Connection
Available 30mm and 40mm lengths accommodate different material and fabrication requirements. Both versions use a 1/2" Gas thread for compatible tool holders and share the same 20mm diameter, 6,000 RPM rating, and published traverse parameters.

Common Questions
Frequently Asked Questions
What materials can Alpha CNC Finger Bits cut?
Alpha recommends these finger bits for porcelain and sintered slabs, including Dekton® and Neolith®. They are also designed for crystallized glass and other compatible vitreous materials. Machine setup, tool-holder compatibility, and working parameters should match the selected material and fabrication requirements.
Which machines are compatible with the finger bits?
The finger bits are designed for compatible CNC machines and radial arm workstations. Both sizes require a tool holder that accepts a 1/2" Gas thread and can operate within the listed 6,000 RPM limit and published traverse parameters.
What fabrication applications are these finger bits designed for?
Alpha identifies its CNC finger bits for sink-hole cutouts and exterior cutting applications in compatible porcelain, sintered slab, and vitreous materials. Their segmented construction and machine-controlled operation support detailed fabrication after the proper tooling and machine setup have been selected.
What is the difference between FBD030 and FBD040?
The FBD030 has a 30mm tool length, while the FBD040 has a 40mm tool length. Both versions have a 20mm diameter, 1/2" Gas thread, and 6,000 RPM maximum. Select the length suited to the material thickness and planned fabrication work.
What tool-holder connection do the finger bits require?
Both sizes use a 1/2" Gas thread designed for compatible CNC and radial arm tool holders. Confirm the exact thread connection before ordering because the machine must accept this attachment method along with the tool's 20mm diameter and selected working length.
What working parameters does Alpha recommend?
For 3/4" (2cm) material, Alpha lists an operating speed of 6,000 RPM, a traverse speed of 10" (250mm) per minute, and a traverse exit speed of 5" (125mm) per minute. These published parameters apply to both available lengths.
How do the finger bits help reduce blow-out?
Alpha selects the diamond formulation and matrix to minimize blow-out where the tool exits the material. This feature is especially valuable when fabricating hard porcelain, sintered slabs, and vitreous surfaces where protecting the finished edge is an important consideration.
Can the finger bits be used on materials not listed by Alpha?
The product is centered on porcelain, sintered slabs, Dekton®, Neolith®, crystallized glass, and other vitreous materials. Compatibility with unlisted materials should not be assumed because performance depends on the surface composition, machine, tool holder, speed, and traverse settings.
