Really enjoying AXYZ’s weekly tips, especially when it’s something recently discussed in other circles – in this case polycrystalline diamond (aka ‘synthetic diamond’) CNC bits:
The notion of PCD tooling has been a hot topic of late and with very good reason. These tools are much more expensive than the solid carbide router bits which we’ve all come to love, but is the price justified? This blog reviews PCD tooling and discusses the applications in which a PCD tool should be your tool of choice.
What is PCD?
Polycrystalline Diamond (PCD) tooling is composed of diamond particles that are sintered with a metallic binder at extreme temperatures and pressures. This manufacturing method allows diamond particles to be fused onto a carbide substrate and creates the hardest and one of the most abrasive resistant materials used in CNC router bits.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
