TOP HAMMER BITS / CASING SHOES
Top hammer bits consist of a steel body with cemented carbide buttons or inserts on the face of the bit. These buttons are arranged in a pattern that maximizes the drilling efficiency and reduces wear on the bit. The carbide buttons are made from a tough and wear resistant material, which allows the bit to maintain its cutting performance for longer.

PWF Long Standard / PWF Long Set to Liner
Stepped drag bits are a type of drill bit used for drilling holes in soft to medium-hard formations such as sandstone, shale, and clay. These bits are designed with a stepped profile, which means that they have different sizes of cutting elements placed at intervals along the length of the bit.
TUNGSTEN CARBIDE INSERT BITS
From precision-engineered cutting structures to robust Tungsten Carbide Inserts strategically placed on the cones, these bits guarantee extended lifespan, optimal penetration rates, and reliable results.
STEEL TOOTH TRICONE
Our Steel Tooth Tricone Bit models are designed with long “A” shaped teeth, widely spaced and fully hard faced from crest to root for maximum penetration rates in formations that range from moderately soft to medium soft.
FULL FACED PCD BITS
We offer a wide range of full-hole drill bits with polycrystalline diamond cutters (PCD). These span between small bits 3” diameter used in mines for drilling holes for roof-bolts to larger diameter bits used for horizontal drilling. All these bits have a full tungsten carbide matrix crown imparting a much superior wear resistance than equivalent steel-head bits.
PCD Coring
PCD (polycrystalline diamond) coring bits are a type of diamond drilling bit used in various industrial applications. These bits are made of a polycrystalline diamond layer that is bonded to a tungsten carbide substrate, providing high wear resistance and durability. We use these different types of barrels:
- T6-116 Standard / T6-116 Set to Liner
- T2-101 Standard / T2 -101 Set to Liner
- T6-101 Standard / T6-101 Set to Liner
- 412 Standard / 412 Set to Liner
- PWF Long Standard / PWF Long Set to Liner
- PWF Long Standard / PWF Long Set to Liner
DTH - DOWN THE HOLE
Our DTH system boasts advanced features that set it apart from the rest. With its state-of-the-art down-the-hole hammer technology, you can achieve faster and more accurate drilling operations, ensuring optimal penetration rates and reduced downtime. We use DTH from 2 ½ to 18inch drilling. Special sizes will be available upon request
DRILL RODS
We offer All types of drilling rods for conventional and wireline drilling. The exceptional durability of METADRILL WJ rod can be attributed to the high strength alloy teel and the superb plasma arcwelding process
ADAPTERS
Adapters are critical components of the drilling system and play a significant role in the overall drilling performance. The quality and compatibility of the adapter with the drilling rig and bit can have a significant impact on the drilling efficiency and accuracy.
MANUAL/AUTOMATIC SPT ASSEMBLIES
The Standard Penetration Test (SPT) assembly is a widely used in-situ testing method in geotechnical engineering to determine the geotechnical properties of soils at various depths below the ground surface.
METADRILL offers you both Manual Trip hammer or the Full Automatic SPT Assembly.
SAMPLING CONES/SPLIT TUBES
Sampling cones are specialized tools used in geotechnical and environmental drilling to gather soil or sediment.
These cones are typically attached to drilling equipment, such as cone penetration testing (CPT) or standard penetration testing (SPT) rigs.
Split tubes, also known as split spoon samplers or split core barrels, are widely used tools in soil sampling operations, particularly in geotechnical and environmental investigations.
