Maintenance of the DTH bits
As DTH bits are consumables, the maintenance of the DTH
bits in daily life can extend the bits’ service life and reduce the cost. Once
finishing the drilling work, we should examine the situation of the button of
bits. If the buttons are worn down a lot that affect the drilling efficiency,
we recommend a hand-held tool to sharpen the button.
It is a complete manual grinding system with easy and
simple operation. Driven by air, its inner rotor can reach over 22000RPM that
can sharpen the worn-down button in a few seconds, making grinding job
efficiently.
