Products Description LEANOMS
DTH Hole Opener Bits from rock drilling tool maker LEANOMS are made from the best aviation alloy steel. which are most frequently used for foundation drilling, blast hole drilling, quarrying, DTH drilling, water well drilling, oil drilling, and construction to extend the size of a pilot hole.
LEANOMS provides DTH Hole Opener Bits in a variety of sizes, including 3.5 inches, 5 inches, 6 inches, 8 inches, and 12 inches, with all DTH hammer shanks used in the industry as a match.
For a variety of down-the-hole hammer drilling application needs, including those related to drilling rig and equipment capabilities, worksite conditions, and job specifications, LEANOMS DTH Hole Opener Bits can provide hole enlargement.
LEANOMS DTH Hole Opener Bits are also offered in a variety of designs, each of which may be best suited for particular uses. This device is frequently used in industry to drill holes with extremely large diameters.
When trenching and excavation are impractical, DTH Hole Opener Bits is employed. This drilling technology enables steerable, trenchless underground drilling. There are three steps, the first of which is to drill a pilot hole with a small diameter. The second step is to enlarge the hole using a reaming or DTH Hole Opener Bits with a larger cutting diameter. The third step is placing the casing pipe or other item within the bigger hole.
Products Advantage LEANOMS
DTH Hole Opener Bits Feature Advantage:
1. Factory direct marketing reduces expenses.
2. Professional heat treatment techniques and high wear resistance are used to ensure quality.
3. Stable inventory, detailed product information, and a wide variety of models.
4. After-sale warranty: 24-hour after-sale service system, so you can relax.
5. Wear pads, buttons for the back reamer, and/or buttons for the pilot can be added at an extra cost.
6. The ability to employ equipment with less power than what is necessary to drill a hole with a big diameter.
7. The smaller pilot hole produces straighter holes.
8. Better material clearance after cutting.
Products Description LEANOMS
"DTH Hole Opener Bits" and "Regular DTH Bits" refer to different types of Down-the-Hole (DTH) drill bits used in rock drilling and mining applications. Here are the key differences between the two:
Function and Purpose:
DTH Hole Opener Bits: These bits are specifically designed for enlarging existing boreholes or drilled pilot holes. They are used to increase the diameter of the hole, typically after a smaller initial hole has been drilled.
Regular DTH Bits: These are standard DTH drill bits designed for the primary drilling process. They create the initial hole or pilot hole in the rock or other formations.
Design:
DTH Hole Opener Bits: They have a design that allows for the efficient enlargement of the hole. They often have a larger diameter than regular DTH bits and are equipped with additional cutting structures for this purpose.
Regular DTH Bits: These bits are designed to cut into the rock efficiently to create the initial hole. They come in various designs based on the rock type and drilling requirements.
Size and Diameter:
DTH Hole Opener Bits: These bits are typically larger in diameter compared to regular DTH bits. The size of a DTH hole opener is specified by the final desired hole diameter.
Regular DTH Bits: They come in various sizes depending on the application and the required hole diameter.
Application:
DTH Hole Opener Bits: Used in applications where an existing hole needs to be enlarged to a larger diameter, often in mining or construction projects.
Regular DTH Bits: Used for the primary drilling process to create holes of various diameters in rock or other geological formations.
Drilling Process:
DTH Hole Opener Bits: Used after the initial hole has been drilled, either with a regular DTH bit or another method. The hole opener enlarges the hole to the desired diameter.
Regular DTH Bits: Used in the initial drilling process to create the pilot hole or the main hole.
