Cutting edge
The anti-seismic design of the cutting edge can slow down the vibration during the processing and improve the quality of the processed surface.
The drill bit has a large chip removal space: small chip removal resistance, smooth chip removal, low drilling heat, and reduced drilling pollution;
Cutting edge sharpness: Due to the use of nanotechnology and advanced grinding technology, the cutting edge of the drill bit is sharper than before, which can reduce cutting force, reduce drill breakage rate, and improve hole wall quality;
Tool design based on customer application: A wide range of drill bits can meet different application needs. All parameters of the drill bit, such as drill core thickness, drill core taper, etc., are well-designed and very practical;
The cutting edge is strictly symmetrical: it is conducive to cutting and avoids drilling deviation.
