Surface Treatments

A full array of surface treatments and coatings are available to enhance the taps performance depending on application and material being tapped. Listed below are the standard treatments we offer. Please consult factory for price and delivery on the new coatings.

Reiff & Nestor Company now has to offer for tapping all the exotic materials.

NITRIDE** Recommended where abrasive or wearing conditions exist. It may be used for ferrous, nonferrous, or nonmetallic materials.

NO. “5” Is very effective where an anti-galling characteristic is required, combined with high wear resistance. Recommended for use in ferrous materials.

NO. “0” This treatment imparts a lubricant retaining surface that has high anti-galling characteristics. It is recommended for use in ferrous materials.

CHROME A special Bright Hard Chrome plating process developed to increase tap life and impart an antigalling surface to taps. It is recommended for use in all materials.

CONIT* Developed for use where extremely abrasive or wear-inducing, materials are encountered, both ferrous and nonferrous.

BLUE DIAMOND Is a specially treated electro chemical surface designed to eliminate surface welding when tapping soft stringy materials.

TITANIUM NITRIDE (PVD) Is also available upon request. (Prices for this treatment are available from our Sales Department.)

MULTICOAT C3 Multilayer Coating recommended for machining softer materials such as titanium, aluminum, and copper alloys, Good anti-galling properties, (Consult factory for pricing.)

MULTICOAT C4 Multilayer Coating having high hardness and anti-wear properties. Recommended for tapping tool steel, mold steel, and other heat treated materials. (Consult factory for pricing.)

* The Conit treatment has been broken down into progressive degrees of surface concentration called Conit-1, Conit-2, Conit-3 and Conit-6 — the larger number indicating the greater wear resistance.

** The Nitride treatment has been broken down into progressive degrees, as found applicable to various materials and tapping conditions. These treatments are: 1-N, 2-N, 3-N and 6-N. For ferrous, nonferrous and nonmetallic materials which cause dulling of the tools because of their abrasive characteristic. The numbers are individual specifications applied by our engineers for particular applications.
