Product Description
Flat Drill Bit (Single-Blade Bit)
Flat drill bit (also known as straight-blade drill bit, flat rock bit) is a core rock drilling tool suitable for soft to medium-hard rocks in rock drilling operations. Specially designed for hydraulic/pneumatic rock drills and pneumatic drills, it adopts a structure of single-blade symmetrically distributed cemented carbide cutting edges and high-strength alloy steel matrix, and is accurately connected to the drill rod through standard threads such as R32 and T38.
Widely used in coal mining, soft rock tunnel excavation, coalbed methane drilling, building foundation soft rock construction, geological exploration and other fields, it supports both dry and wet operation modes. Its core advantages include small cutting resistance, fast centering and smooth slag discharge, greatly improving soft rock operation efficiency and construction stability.
Fast Centering & Straight Drilling:
Single-blade symmetric cutting structure with precise blade guidance, which can complete centering instantly when contacting the rock formation. The drilling verticality error is ≤0.8%.
Smooth Cutting & Minimal Resistance:
The cutting edge is forged with cemented carbide and designed with an arc blade. The cutting resistance is 30%-40% lower than traditional multi-blade drill bits.
Quality Control & Service
In terms of quality control, a scientific, standardized, and institutionalized full process quality inspection system has been established. From raw material procurement and warehousing to finished product delivery, strict inspection standards are implemented. Professional inspectors and advanced testing equipment are used to ensure zero defects. A 24-hour technical response mechanism provides customers with guidance, maintenance training, and troubleshooting.
