Thank you for viewing. This is a scrap piece of Daiflon round bar. Size: Φ20 x 20mm (The length that seems to be the processable range is 20mm, and the actual product is a little longer.) Quantity: 17 pieces, sold as a set These are scraps from processing new materials. Materials have become expensive these days, making them valuable. We can no longer use them mechanically, so we are selling them. The manufacturers are a mix of Yodogawa Seisakusho and Daikin. Daiflon is a PTFE-based fluororesin, a high-performance resin with excellent chemical resistance and heat resistance. Please use it for research, trial production, DIY projects, etc. Due to the short length of the scraps, they are more suitable for prototypes and crafting materials than for practical use. They should be easy to process with 3-jaw or 4-jaw general-purpose lathes or desktop lathes (This is my personal opinion, but please be careful as the material is short when processing.) Please understand and purchase. No claims and no returns are accepted. It may take 4-5 days to ship. We will do our best to respond quickly and carefully. ✦ Instant purchase OK ✦ Shipping included (Shipping will be via either Nekopos or Takkyubin Compact.) ✦ Please feel free to negotiate the price.
