BSN Medical Teflon PTFE Cast Saw Cutter Blade | 31-0265 |7203315| 2.5 Inch |

PTFE (Teflon coated)
Teflon is a very lubricious, slippery coating which is applied to the stainless-steel blade. The process is much like spray painting and takes place at room temperatures. When dry, and cured, the Teflon provides a non-stick, low drag coefficient surface that slides smoothly through casting materials.  The drawbacks are that Teflon tends to wear off not long after first use. So, despite the low friction surface, the material often fails to stay permanently bonded, so some degradation is seen. Despite this small downside, PTFE-coated blades remain quite popular.

Blades fit a variety of cast saw types. Hex heads have a 6-sided hexagon on the top hub, whereas pin head saws have a pin that runs through the middle of the head, then secured by a nut.
