Any gauge wear to the bit-face and bit-skirt is now more synchronous due to the steps on the skirt, and the skirt always has sufficient gauge to provide good guidance in the hole.Not only does this improve the long-term rotating ability of the drill bit, it also reduces wear, cuts energy demands and provides better quality holes.Uniface drill bits combine the best features of the former Flat-Face series of bits (for hard, abrasive rock formations) with those of the former Drop-Center series (for mixed rock conditions and fractured formations).One characteristic is the high number of buttons in the face, as well as their optimal placement and larger dimensions.  1. Made by high quality alloy steel bar and tungsten carbides. Through heat treatment, they are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks.2. In addition, customized thread button drill bits are available according to different drilling application, and custom drill bits are applicable to drill soft rock, medium hard rock and hard rock.Process & 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.
