Cone-shaped bit, a small diameter at the top to ensure that the performance of cutting cone into the ground to reduce the cutting resistance; diameter of the bottom bit, the shank to provide protection. Bit connected through a special metal brazing on the knife handle, high bonding strength, can withstand applied to the tip, the bending moment and handle a 45-degree direction 6 t force generated.
Road milling bit of the shank upper and lower portions have different mechanical properties, the upper half to create friction with the road surface and milling waste, so they need high hardness, the lower half of the rod into the knife block, you need to be able to absorb the milling shock during planing, so good toughness. Such holders will need to have a dual performance: wear and bending. In the middle there is an undercut, you can use removable knife pliers pulled out the knife blade holder (some heads did not undercut, the use of head punch it out from the rear). Some new heads, handle head cloth with grooves also increases the friction with the ground rotation performance in the process, prevent partial wear.
