Most Reiff and Nestor metric tap sets offer a full array of surface treatments and coatings. Each metric tap set with these special treatments is available to enhance the metric tap set performance
depending
on application and material being tapped. Listed below are the standard treatments
we offer for our metric tap set products. Please consult factory for price and delivery on the new metric tap set coatings Reiff & Nestor Company now has to offer
for tapping all the
exotic materials.
METRIC TAP SETS WITH NITRIDE** Recommended where abrasive or wearing conditions exist. It may be used for
ferrous, nonferrous,
or nonmetallic materials.
METRIC TAP SETS WITH NO. "5" Is very effective where an anti-galling characteristic is required, combined
with high wear resistance.
Recommended for use in ferrous materials.
METRIC TAP SETS WITH NO. "0" This treatment imparts a lubricant retaining surface that has high anti-galling
characteristics. It is recommended for use in ferrous materials.
METRIC TAP SETS WITH 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.
METRIC TAP SETS WITH BLUE DIAMOND Is a specially treated electro chemical surface designed to eliminate
surface welding when
tapping soft stringy materials.
METRIC TAP SETS WITH TITANIUM NITRIDE (TiN) Is also available upon request. (Prices for this treatment are
available from our Sales Department.)
METRIC TAP SETS WITH MULTICOAT C3 (CrN) Multilayer Coating recommended for machining softer materials such as
titanium, aluminum, and copper alloys, Good anti-galling properties, (Consult factory for pricing.)
METRIC TAP SETS WITH MULTICOAT C4 (TiCN) 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.)
* Metric tap sets with 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.
** Metric tap sets with 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.
