hardware-cutting tool

ULTRA POINT DRILL(Solid carbide drill) Extremely,3 time fast than the speed of HSS cutting feed. -Improve centering, 7 times long tool life by special coated(Tin,TiCN,TiALN) -ULTRA POINT DRILL proper in Automation machinery and machining center because cutting chip break. -Ultra point drill is possible to drilling in 3 times of diameter at once and ULTRA oil hole point drill is possible to drill in 5-7 times of diameter at once. -It is much improved hole accuracy and roughness,so it is not necessary centering & reaming process(the accuracy of hole diameter and hole position is under 0.05mm)
