Big Hole Black Blanks (7”)

This listing is for 7" big hole black blanks, sold in packs of 10.

All blanks made with the highest quality 2mm PETG, this means that your swarf is the same colour as the disc, for example:

• Transparent discs have transparent swarf
• White discs and white swarf
• Black discs have black swarf
  

All Spinner Town blanks are exactly the same material and will cut the same. If you have already purchased  or sampled our white blanks and like them, then you will like the black.

The reason we are making this point is due to the lathe cutting world previously working with other black discs from other suppliers. The way they work is like a sandwich, a black plastic which is then covered in a thin transparent layer of plastic to cut into. This is why your swarf is transparent, yet your discs appear black.

We are not working like this, rather using 100% PETG. It costs way more for us to produce as it is specialist, but we believe it is worth it. The plastic is manufactured perfectly flat, without the need for secondary processing which can cause problems such as warping.

Cutting Info

Heat lamps are not needed for clean cuts with the lowest possible noise floor. Please ensure the room is warm, and if using a heat lamp, use sparingly. 

Ideal room and disc temperature is 23 to 26 degrees for the optimum humidity levels while cutting.
