Honing tool and method of making
First Claim
1. A method of making a honing tool comprising the steps of forming a compact bundle of relatively short abrasive containing monofilaments, inserting the bundle into a holder so that a portion of the monofilaments projects a uniform short distance from the holder with the tips of the monofilaments forming the working face of the tool, and encapsulating said bundle in an elastomer to provide improved support for said portion of said monofilaments.

Abstract
Honing tools and methods of making such tools utilize a compact bundle of abrasive containing plastic monofilaments projection a relatively short distance from a holder with the compacted tips forming the working face of the tool. The bundle may be secured to the holder by a thin layer of adhesive or by a clinched or swaged girdling lip or rim on the holder which embraces the bundle. In addition, the bundle is further infused with an elastomer, preferably foamed. The bundle is enclosed in a mold which may be part of the clinching process and an elastomer is injected into the mold to infuse and encapsulate the bundle. The encapsulation fills the interstices of the bundle and form an integument around the bundle in effect making the tip action tool into a solid yet elastic block. This enables the abrasive monofilaments to have a higher abrasive loading since they are additionally supported by the matrix, and the tool to be applied at higher pressures. The matrix may be injected through the working face, the bottom of the holder or through mechanical anchor holes in the sides of the holder.
