The New Uniface bitsare expected to add value through higher productivity, better blasting results and lower rock-excavation costs.   The guidelines for choosing the right Uniface bit are1. spherical buttons for very hard rocks;2. ballistic buttons for less-hard rocks;3. regular bit-skirt for solid homogenous formations;4. retrac skirt for mixed, jointed or fractured formations.   The versatility of Uniface bitsmeans, however, their respective ranges of use are now much wider than before and the changeover boundaries are less strict.Retrac button bitTop ViewDiameterButton NumberThread TypeButton ShapePackage  64mmFront:4      Guage:8T38Spherical8pcs/ctn 76mmFront:4      Guage:8T38/T45/T511.Parabolic 2.Mixed 89mmFront:5pcs      Gauge:8pcsT38/T45/T511.Spherical 2.Parabolic 3.Mixed6pcs/ctn 102mmT51Mixed4pcs/ctn 115mmProcess & Application:Procedure:Shipment & Payment:FAQ:Q:Can I get some samples?A:Yes,sample orders are welcomed.Q:Have thread button bit assembled well in stock?A:No,all thread button bit will be newly produced according to your orders including samples,but we have some stock for your urgency.Q:Could I use my own logo or design on goods?A:Yes,customized logo and design on mass production are available.Q:Can I choose the colors?A:Yes,customized color is available.Q:What is the delivery time?A:A week for sample,15-30days for mass production.Q:What is the payment term?A:T/T,L/C at sight,Western Union,Paypal etc.Q:Can I trust you?A:Absolutely sure.We are famous company in china and "alibaba" verfied supplier.Q:May I visit your factory?A:Sure,welcome any time.We can also pick you up at airport and station.Related Product: Exhibition & Visit:About us: 1.China biggeest manufacturer.2.More than 15 years professional experience of producing rock drill bit.3.Professional producing team,quality control team,engineer team and sales team.4.Super after service.5.Powerful production ability.Certifications:
