What Is the Delrin Die for the 186.00A Bender?
The Delrin die is an optional accessory designed specifically for the #186.00A Ring Shank Bending Tool. If you already own or are considering that bender, this die gives you a way to bend softer materials—like precious metals or delicate wire—without leaving tool marks.
Delrin is a high-quality engineering plastic known for its hardness, low friction, and resistance to wear. Unlike a standard metal die, Delrin is non-marring, making it a smart choice when surface finish matters.

When to Choose Delrin Over a Metal Die
A metal die is durable and works well for hard materials like steel or thick wire, but it can leave impressions, scratches, or polish marks on softer metals such as silver, gold, or annealed copper. The Delrin die solves this: its slightly softer surface grips the workpiece without digging in or transferring tool texture.
Use the Delrin die when you are bending finished pieces, pre-polished wire, or any material where surface integrity is a priority. If you routinely work with hardened steel or need heavy repeated bending, a metal die may still be the better long-term choice for durability.
Compatibility: It Only Fits the 186.00A Bender
The Delrin die is not a standalone tool. It is an accessory for the #186.00A Ring Shank Bending Tool. Before purchasing, confirm that you own or are acquiring that specific bender. The die is made in the U.S.A. and is available in a standard variant.
If you have a different bender model, this die will not fit. Check your tool's compatibility before ordering.
What the Evidence Does Not Cover
The supplied information does not include operating instructions, recommended bending radii, or maximum material thickness for the Delrin die. For those details, refer to the documentation that comes with the #186.00A bender or contact the manufacturer. The die's performance also depends on proper setup and technique.
