Product Description

The Uniface comprises a series of three new, universal bit-face designs:
one for Ø51-64mm bits;
one for Ø70-96mm bit;
one for Ø102-152mm bits.
 
The Uniface design brings together, in a single drill bit, a range of features that formerly necessitated two or more different models. 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 are:
1. 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.

Application and Advantages:
All Uniface Retrac bits feature a new stepped-splines Retrac skirt, designed to give the best possible hole-straightness and retract ability in mixed and/or fractured rock formations.
Since the long, splined skirt is stepped diametrically, bit rotating ability improves immediately. 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.
