Product Introduction LEANOMS
DTH drill bits are tools designed for rock drilling by directly sending the drill bit down the hole using a drill rod. These bits are engineered to adapt to various types of rock, offering efficient, fast, and flexible drilling characteristics.
Product Design LEANOMS
The DTH Drill Bits' heads are designed to fit specific rock formations. It often comes in four shapes:
1. Plane type： The type is appropriate for severely corrosive and hard rock formations.
2. Concave type: This type DTH Drill Bits appropriate for all types of rock formations, particularly medium-hard and homogeneous rock formations
3. Convex kind is appropriate for soft-medium-hard layers.
4. Type of center depression: The DTH Drill Bits appropriate for cracked and soft, medium-hard, and hard rock formations
There are primarily three types of alloy teeth used in DTH Drill Bits:
Ball teeth, Animal thread teeth, and Spring teeth. These alloy teeth come in a variety of designs.
It is crucial to select an appropriate DTH Drill Bits shape when utilizing DTH drilling equipment since it may increase productivity and save expenses.
Ordering Instructions: Bit Diameter, Shank, Face form, Carbide Button Shape.
DTH Drill Bits have a limited range of rocks they can break with each contact. When the speed of the drill bit is too high, it will inevitably leave behind a portion of the rock tumor that is not broken by impact between the secondary chisel marks, which increases the rotary resistance moment, aggravates the vibration of the drilling machine, and accelerates the wear of the carbide on the DTH Drill Bits end face and radial, which not only slows down drilling but even results in drill clamping accidents; The phenomena of recurrent crushing may happen when the rotation speed is too low.

Product Introduction LEANOMS
Key Components:
Cutting Structure: The cutting structure of DTH drill bits is typically made of hard alloys to enhance hardness and wear resistance.
Cooling System: DTH drill bits often include cooling holes, introducing coolant into the cutting area to reduce temperature and extend tool life.
Flush Holes: Some DTH drill bits have flush holes designed to expel rock cuttings from the hole during the drilling process.
Connection Section: The part connected to the drill rod ensures the smooth transmission of rotation and thrust forces.
Packing LEANOMS
Using ply-wooden cases and pallet for package to protect the products and avoid the damaging during transportation. Also we can customize package according to your special requests.
