Stepped drag bits are drill bits used to drill holes in soft to medium-hard formations such as sandstone, shale, and clay.
These bits have a stepped profile, meaning they have different-sized cutting elements spaced along the bit.
The cutting elements on stepped drag bits are typically made of tungsten carbide or diamond inserts, which provide high wear resistance and durability.
The stepped design allows the bit to penetrate the formation more efficiently and reduces the risk of getting stuck in the hole.
We supply all sizes of drag/clay bits

- Faster drilling cycles: Core is retrieved without tripping the rods, cutting non-productive time.
- Deep-hole capability: Efficient and economical for deep drilling where conventional coring becomes slow.
- High core quality: Good recovery and well-preserved samples for logging, assay, and testing.
- Borehole stability: Rods act as temporary casing, protecting the hole in difficult formations.
- Lower labor and wear: Less handling of rods reduces operator effort and equipment wear.
- High penetration rate: Direct percussive impact for efficient drilling in hard rock.
- Durable construction: Heat-treated, wear-resistant components for long service life.
- Reliable performance: Stable operation across a wide range of air pressures.
- Easy maintenance: Simple design that is quick to service and repair.
- Versatile use: Suitable for water wells, exploration, geotechnical drilling, and quarry work.
