RK3-PT Kennametal Concrete Grinder Teeth For Road Stabilization And
1. Road Milling Bits Description
Road milling bits are also known as asphalt and concrete cutting
bit, road planning picks, road milling machine cutter teeth, which
are used as wear parts of road milling machine in road
construction. Bit is installed in milling drum of milling machine
and cut the road surface. The bits have two type, asphalt bits and
concrete bits. Different bits are used on different aggragate and
different milling machines.
Alloy steel Body, made by material ASTM4142 or 42CrMo,heat
treatment with 40-44HRC hardness, has high toughness and wearable
character. Tip with above 50 HRC hardness is made from low press
sintered technology, reasonable proportion of tungsten cobalt alloy
to ensure the wear resistance and fracture resistance of the
SRK3-PT is cylindrical carbide tip for removing concrete, pick head
without or with extractor groove as a dismantling aid. The shank
diameter is 20mm, carbide tip diameter is 13mm, recommend for the
large milling machines of Wirtgen, Dynapac, Cat, Kennametal and

4. Carbide Milling Tips Character
- Be used for road milling, ground stabilizing, cutting asphalt and
- the material of tooth body is 40CrMo or better, the machining
process is forged
- Various design can be applied to most of cutting conditions
- High purity carbide tips are used for great strength
- Consistently high, pore-free tungsten carbide quality produced
through an exact process resulting from years of experience
5. Carbide Picks Structure
1. Reasonable proportion of tungsten cobalt alloy to ensure the
wear resistance and fracture resistance of the cutting pick.
2. Excellent flow solder to ensure weld strength.
3. Unique design of the body to improve the efficiency of
retraction, to ensure smooth rotation, new heat treatment process
to guarantee the wear resistance and fracture resistance of the
4. Thicken gasket design, ensure long life of the toolholder.
5. Thickening the sleeve, ensure moderate tension and clamping
force, easy installation and removal.
6. Milling Machines Type
