Packing: 20pcs ( 2pcs for each Value ) 2 x Plastic box

Fit for: PCB drilling machines, engraving machine, CNC and high precision special drilling equipment

Carbide rods and tungsten steel rods, with high hardness, high wear resistance, high strength, resistance to bending, anti-impairment and long tool life
Large drill bit chip space, chip resistance,Chip smooth, small drilling heat, reduce smear.
Drill has a large scraps discharge space,little resistance and smoothly during the scraps discharge.
Using high quality materials and fine grinding process makes bit more sharp cutting edge,reduce cutting force and broken drill and improve the quality of hole wall.
Cutting edge strictly symmetrical: beneficial and efficient cutting, avoid offset drilling.
