CNC router carbide inner coolant twist drill bits for metal drilling
Inner coolant drill as HSS drill or carbide drill
The inner coolant channel is used for optimum tool cooling directly on the tool cutting edge. On modern drill lines, an air - coolant lubricant mixture is forced through the holes directly into the borehole at high pressure. This mixture optimally reduces the dissipation of the extremely high frictional heat generated during the machining of the steel profiles and steel plates.
Using high-quality tungsten material, high-precision imported Germany Wlater CNC machine processing, so the drills have high centering ability and can get a stable dimensional accuracy and good surface quality; be suitable for processing system excellent rigidity occasions.
