The most common tooth types are the regular tooth and
the variable tooth. (Variable tooth is only available in
the Bi-Metal). See Below.
REGULAR TOOTH - Straight faced tooth with deep gullets
to rake out chips. This style is used for general metal cutting.
HOOK TOOTH - Widely spaced teeth and deep gullets with
teeth that have a ten degree undercut face which helps to
dig in and take a good cut while the gullets tend to curl
the chips. This type is good for harder nonferrous alloys,
harder woods and many plastic operations. Available in raker
set only.
SKIP TOOTH - Very similar to the hook tooth but characterized
by a straight 90 degree tooth and a sharp angle at the junction
of the tooth and gullet This type tends to break up the chips
This style is good for soft nonferrous metals that have a
tendency to gum and clog the blade and it is also popular
in wood cutting. Available in raker set only.
VARIABLE TOOTH - (Bi-Metal only) Also known as vari-tooth
or broach tooth this tooth has varying set angles and gullet
depths The variable tooth cutting edge reduces vibration
while the back absorbs the impacts of cutting in and out
of holes slots and narrow webs This is the best all-purpose
blade for production work and for general shop cut-off and
contouring. Use it for cutting off solids bar stock and especially
structural. |
