Description

Polycrystalline PCD Router Bit | 90° V-bit | Amastone

Polycrystalline diamond (PCD) bits are ideal for engraving granite, quartz, and lava stone on CNC machines and CNC routers.

Angle: 90°
Cylindrical shank: 10mm dia
Bored with the inner water flow

Recommended operating parameters:

7000/8000 rpm
Feed rate: 200/250 mm per minute
Max plunge depth 2 mm
Plunge rate (the rate at which the cutter is moved vertically into the material or during ramping moves): 50 mm/min – 20% of the feed rate
We recommend ramp movent for stone penetration
We recommend both internal and external water.

I am looking for a diamond bit that won't dull I'm cutting into a 60% limestone composite product for flooring do you have something that may work better than the carbide tool I am currently using?

Hi Ray,

Carbide tools are typically suitable for softer materials, while polycrystalline diamond (PCD) tools are designed for harder materials like granite.

If you're currently using carbide bits and they’re wearing out too quickly, it’s likely because the material is too abrasive or dense for carbide. In that case, switching to a PCD tool would be a better solution—it offers much greater wear resistance and durability.

I hope this answers your question! If you need further assistance or would like a specific recommendation, feel free to contact us anytime.

Hi Can the PCD router bits work effectively running at 6000RPM, the maximum of a machine I am looking at? Thankyou

Hi Niall, for granite, the recommended spindle speed for PCD router bits is typically around 7000–8000 RPM, so running at 6000 RPM is still acceptable.
We just suggest slightly reducing the feed rate to compensate for the lower rotation speed.

When you start, always begin with a slower feed and monitor how the machine and tool behave.
Also, we strongly recommend making a ramp entry into the material (not a straight plunge) to avoid damaging the PCD tip at the entry point.
