Tungsten Carbide Burs for TOUGH Applications
NEW
.
TOUGH-Burs represent a PFERD product line devel-
oped for users whose required applications result in
tooth breakage and bur failure, rather than normal
wear. Designed especially for hand-held applica-
tions in tough operating conditions common to
shipyards, foundries and on steel fabrication.
Advantages
Innovative, special cuts providing exceptional
impact resistance.
These extremely durable, high-performance cut
patterns minimize tooth chipping/breakage,
splintering and bur head failures.
The 3R and 3RS cuts can be used on materials up
to 55 HRC.
These products can also be used at low speeds.
Their extremely high impact resistance means
that they are perfectly suited for use as long
shank variants. Available in special shaft lengths.
Developed specifically for applications involving
high impact loads, the new 3R and 3RS cuts are
the latest addition to the existing PFERD range.
Application Examples
High-impact applications due to long shank
design.
Heavy-duty applications, due to angled
working.
High angle of surface contact.
Milling of narrow contours.
