Products Description LEANOMS
LEANOMS Thread Shank Adapter are made of high-quality steel and are designed to give ideal wear resistance, strength, and toughness for maximum energy transmission from the hammer to the drill string.
Rock Drilling Tools T38 Thread Shank Adapter is an essential downhole tool used for connecting drill bits and accessories to the drill steel/tooling string in DTH hammer drilling operations.
The "T38" refers to its 38mm diameter threaded ends, which complies with common thread specifications for many rock drill bits and tools. This standardized sizing allows the shank adapter to be compatible with a wide range of drilling equipment.
One end contains a male T38 thread profile that directly screws into the rear female receptacle of drill bits, reaming heads, casing installers and other downhole components. The opposing end has an matching female thread for locking onto the male end of drill steel inserted from the rig.
Company profile LEANOMS
The shank adapter's job is to transmit rotational torque, feed force, impact energy, and flushing medium to the drill string, also known as the shank adaptor or shank adapter.
As a result, the shank adapters are made of specially chosen material that is also cauterized to harden it so that it can withstand the high impact power of modern rock drills. There are currently about 300 different shank adapters available for various rock drills from the Atlas Copco, Tam Rock, Garden Diver, and other drifter series.LEANOMS means Lean Operation, Lean manufacture and Lean Service, reflecting our dedicated industry focus, pursuit to the high-quality Rock Drilling Tools, and the great importance to customers. We are aiming to be your first choice in rock drilling.
Power is transmitted from the rock drill to the drill stems via Shank Adapter. Male threaded Thread Shank Adapter and female threaded Thread Shank Adapter are the most common. Male shank adapters are more common than female shank adapters. Male shank adapters are typically used in drifting, tunneling, and extension applications where high stresses are present. Female shankadapters are used when drilling space is limited.
Development History LEANOMS
Here is a brief history of the Rock Drilling Tools T38 Thread Shank Adapter specifically:
1960s - Early shank adapters started with coarse internal thread profiles like T38 to basicly connect drill steel to bits. Materials were low-grade steels.
1970s - Rising tunneling and mining drove demand. Refinements standardized T38 as a global construction industry size. Hardened steel improved durability.
1980s - Production drilling boomed. Adapter designs optimized for heavy quarry use through Finite Element Analysis. HARDOX adoption boosted strength.
1990s - Thread specifications were regulated under ISO and API standards for consistent connections. Numerical control aided manufacturing.
2000s - Downhole performance in muds enhanced with seals and coatings. Premium steels like CalDie extended service life furthur.
2010s - 3D modeling refined T38 profiles. Non-destructive test methods ensured connection integrity. Modern grades use machinable tungsten carbide composites.
Today - The T38 size remains dominant due to legacy usage. Newer grades like Supra Alloy 3000 offer double impact/abrasion resistance of steel. Digital inspections and automated assembly aid mass production.
packing LEANOMS
The most common packing methods for Rock Drilling Tools T38 Thread Shank Adapter include:
Bag packaging: Individual adapters are placed inside low-density polyethylene (LDPE) bags sealed with thermal welding. This provides a basic moisture/dust barrier.
Tray packaging: Adapters are arranged snugly in molded plastic trays, with dividers to keep threaded ends isolated. Trays are then stacked on pallets.
Tube packaging: Larger quantities are loaded end-to-end into cardboard tubes of suitable diameter to fully contain the shank length. Tubes are sealed on both ends.
Box packaging: Adapters in trays or loose are nested tightly inside corrugated fiberboard boxes or crates. Interior is lined with plastic or foam sheeting for cushioning.
Reel packaging: Longer shanks are wound around reusable plastic reels which turn to efficiently load/unload from packaging lines.
Strapping/banding: Heavy-duty polyester or steel straps are applied around the exterior of boxes/crates to secure lids during transport.
