Tungsten Carbide Burrs
TC Burrs with Long Shank
Tungsten carbide burrs with
Tungsten carbide burrs with long steel shank
(designation SL 75 mm or SL 150 mm) can, if
long shank (75 and 150 mm)
required, be shortened by the user.
Small tungsten carbide burrs with long shanks
(75 mm) are perfect for work on small hard-
Tungsten carbide burrs with the designation
to-reach components.
GL 75 mm are produced from solid metal
and can therefore only be shortened using

diamond tools.
(150 mm) are ideal for cost-effective work in
deep, hard-to-reach places.
GL = Total length (solid tungsten carbide)
SL = Shank length (long steel shank)
