Product features:
The bit chip space: chip resistance of small, smooth chip removal, drilling small calorific capacity, reduce the drilling sewage;
The extraordinary cutting edge sharpness: due to the use of nanotechnology and advanced grinding technology, bit more sharp cutting edge, can reduce the cutting force, reduce the broken drill rate, improve the hole wall quality;
The application of tool design based on customer: bit rich varieties, to meet different application requirements. Bit all parameters such as thickness, core drilling, core drilling taper, are carefully designed, apparent actual effect;
The cutting edge: strict symmetry facilitates efficient cutting, avoid offset drilling.
