Depending on the shape, there is a variety of Crescent Nicholson
®
files. Suggested files are found in the “job by job” file selector of
this book, or you may contact your Crescent Nicholson

Filing Stainless Steel
The use of stainless steel and alloy steels has created other filing
techniques. These steels with hard chromium and nickel content
are tough and dense. This causes them to be abrasive, which
shortens the life of the normal file.
To overcome these problems, files have been developed with
good wearing qualities. These files, when used with a light
pressure and a slow, steady stroke, will remove metal and provide
a good finish.
Filing Aluminum
Aluminum is soft and is difficult to file; file teeth clog even under
moderate pressure. Filing aluminum is divided into:
• Filing roughness from aluminum castings
• Filing sheet and bar aluminum
• Filing aluminum alloys
To produce a good finish, the
aluminum type A file has been
developed. The file upcut is deep
with an open throat, the overcut
fine which produces small scallops on the upcut. This breaks
up the filings and allows the file to clear. This also overcomes
chatter and prevents too large a bite. By using a shearing stroke
toward the left, a good finish can be obtained.
Filing Brass
Brass is difficult to file because
it is softer than steel, but tough.
This demands teeth that are
sharp and sturdy, cut to prevent
grooving and running the file off
the work.
The Magicut
®
file has a short upcut angle and a fine long angle
overcut which produces small scallops to break up filings and
enable the file to clear. With pressure, the sharp high-cut teeth
bite deep. With less pressure, the short upcut angle smoothes.
