10x nyomtatott áramköri nyomtatott áramköri keményfém mikrofúrószerszám 0,3 mm-1,2 mm N5S4

10x PCB Print Circuit Board Carbide Micro Drill Bits Tool 0.3mm-1.2mm N5S4

bit chip space is large: small chip resistance, chip and smooth, heat a small drill, drill reduce pollution;
extraordinary cutting edge sharpness: As a result of nanotechnology and advanced grinding technology, bit more sharp
cutting edge than before, can reduce the cutting force, reduce the broken drill rate, improve the hole wall quality;
cutting edge strictly symmetrical: beneficial and efficient cutting, avoid offset drilling.
