Diamond Bit
The FATE Engineering Diamond Bit offers safe, fast and long-lasting drilling performance in challenging rock.
About the product
Diamond Bit
A diamond bit is a drilling bit designed for high-performance drilling, particularly in hard and abrasive rocks. Manufactured by FATE Engineering, these bits drill quickly and precisely through rock and mineral surfaces thanks to the industrial diamond grains in their tips. High durability and long life are the most distinctive features of the diamond bit.
The diamond bit's design is optimized to provide maximum cutting and breaking performance during drilling. This shortens drilling time, reduces energy consumption, and lowers drilling costs. Various diameter and diamond hardness options are available to suit different rock types and drilling machines.
Applications
Hard rock drilling in tunnel and mine excavations
Drilling in dam, road, and infrastructure construction
Drilling in hard rocks such as granite and basalt
High-performance applications in difficult geological conditions
Features
Industrial diamond bits at the tip
Maximum breaking and drilling efficiency
Low wear and long service life
Designed for different rock types
Compatible with different drilling machines
FATE Engineering Diamond Bits provide safe and efficient drilling in challenging tunneling and mining projects by offering high performance, reliability, and long life.

Tunnel
Self-Drilling Anchor (SDA)
A hollow, continuously threaded steel anchor system for loose, weathered and collapsing ground that combines drilling, anchoring and grouting in a single operation. Fitted with a drill bit, the bar advances into the ground acting as the drill rod, and remains in place as support once installation is complete. There is no need to insert a bolt into a pre-drilled hole, even where the hole collapses. Cement grout pumped through the bar’s central channel exits through openings in the drill bit, filling the space around the anchor and transferring load between the ground and the anchor. Depending on the method, grouting can be carried out during or after drilling. Bars are joined with couplers to reach the required length, and the anchor head is completed with a plate and nut. Used in tunnel and mine support, slope stabilisation and ground improvement, the bar type, length and drill bit type are selected according to ground conditions and project requirements.

Button Bit
A drill bit used in top hammer drilling for tunnel and mine excavation and for drilling rock bolt holes. Tungsten carbide buttons set into a heat-treated steel body transfer impact energy to the rock and break it. The bit rotates slightly after each blow, so the buttons strike a fresh point on the rock and advance the hole. Flushing holes and channels help clear the cuttings from the hole. Spherical or ballistic button geometry and face design are selected according to rock strength, abrasiveness and fracturing. Produced in a range of diameters with R32, T38 and T45 thread connections; the bit is matched to the hole diameter and drill string.

Tunnel
Cross Bit
Four-wing cross bit with tungsten carbide inserts, giving straight holes and steady penetration in fractured, medium-hard rock. Continuous cutting edges sweep the hole bottom without gaps, keeping the bit on line through fractures. The central port delivers water, air or grout to clear cuttings. On self-drilling anchors (SDA) it is fitted to the bar tip and remains in the hole as a sacrificial bit. In very hard, abrasive rock a button bit is preferred, and in clay or loose ground a clay bit.

SDA Coupler
Coupler that joins self-drilling anchor (SDA) bars to extend the anchor to the required length, rated to match the ultimate load of the bar. It is cut and threaded from seamless tube produced from steel billet in our rolling mill, so every step from raw material to finished part is traceable. Bars enter the coupler to equal depth from both ends, giving full thread engagement on each side. Load capacity is verified by tensile testing. Available in R25–R38 and T38–T51 threads, in lengths of 150–225 mm. Made in the same plant as the bar and nut, so it does not reduce the load capacity of the anchor system.

Tunnel
Nut
Hex nut for self-drilling anchors (SDA) that locks the plate to the bar and transfers load into it, rated to match the ultimate load of the bar. Its spherical seat, used with a dome plate, keeps the load on axis when the anchor is installed at an angle. Made for R32 to R51 threads in the same plant as the bar and coupler.

Tunnel
Bearing Plate
Domed bearing plate that spreads anchor load over the rock or shotcrete surface, rated to match the ultimate load of the bar. The pressed dome stiffens the plate. Used with a spherical nut, it keeps the load on axis when the anchor is installed at an angle. Flattening of the dome under overload gives a visible warning on site. Compatible with self-drilling anchors (SDA) and SN rock bolts, made in the same plant as the bar, nut and coupler.
