It has many sizes, complete specifications, convenient and flexible installation, convenient maintenance, and better cost performance. Wide range of uses. Such as: used in mold manufacturing; chamfering, rounding, grooving of mechanical parts; cleaning of castings, forgings, welding parts of flash, burrs and welds; smoothing of pipes and impeller runners, metal and non-metallic materials (Bone, jade, stone) handicraft carving. It has good chip removal performance, avoids sticking to the kn ife edge, can cut quickly, accurately and smoothly, without burrs, and can process smooth decorative edges. Significantly improve production efficiency. The universal chamfering round shank is easy to use and has good compatibility, which enhances the vibration resistance and cutting speed of the tool, and makes the clamping more firm and non-slip. Product parameters: Material: TCT (tungsten carbide tip) Head shape: wheel type (T type) Blade style: single blade Cutting diameter: 8mm, 10mm, 12mm, 16mm (optional) Shank Diameter: 6mm Applicable equipment: mold grinder The supporting driving speed is generally 6000-50000 rpm.

Single-edge type: The single-edge design reduces drill stress and is superior to the double-edge design when cutting high-hardness materials.
