Description de produit

22mm Small Diameter High Efficiency Rock Drill Bit With Universal Taper Connection For Confined Spaces

Discover high performance 22mm small diameter taper chisel drill bit, low carbon rock drilling tool for underground roadway support, dimensional stone quarry, and tunnel shallow blast holes. Factory direct supply with CE, ISO certification, fits Hex22 taper drill rods and handheld pneumatic rock drills.

Market Context Industry Demand

Global infrastructure localization, Belt Road overseas engineering expansion, and green low carbon mining transformation have reshaped the demand logic of small caliber rock drilling consumables. For small section underground roadways, slope anchoring, stone trimming and municipal foundation reinforcement projects, standard large size drill bits often face operation limitations in narrow construction spaces. The 22mm small diameter taper chisel drill bit fills this market gap perfectly.

New energy mineral exploration (nickel, copper, lithium mines in Indonesia, Zambia, Peru) fuels a huge volume of shallow anchor pre drilling work in narrow roadways. Large button bits are too bulky for confined underground spaces, while the compact 22mm small diameter chisel taper bit matches lightweight Y24 / Y28 handheld rock drills, greatly improving construction flexibility.

The streamlined single blade chisel structure of 22mm small diameter taper drill bit reduces impact resistance, lowers air compressor power consumption by nearly 12%, and cuts waste rock residue accumulation.

Key Features

Compact Small Diameter Body

The optimized 22mm small caliber main body shortens overall bit length, solving the industry point that large drill bits cannot operate in narrow roadways, steep slopes and small stone trimming gaps. Compared with 28mm / 32mm taper bits, its lightweight design eases operator fatigue during long time handheld drilling, highly recognized by municipal and small quarry construction teams searching for narrow space rock drill bits.

Universal Taper Connection System

Built in standard taper socket supports mainstream 7°, 11°, 12° taper angles, fully compatible with global general Hex22 taper drill steel, pneumatic jack hammers and miniature hydraulic drill rigs. The self locking conical friction interface realizes 10 second quick bit replacement, cutting equipment downtime caused by frequent consumable switching — an indispensable advantage for contractors focusing on construction efficiency and equipment idle loss control.

Single Chisel Flat Cutting Head

Integrated high frequency brazed YG8 / YG11C tungsten carbide chisel tooth targets medium hard rock f8 - f14 (limestone, granite, sandstone, marble). Wider chip removal grooves prevent drill jamming when drilling shallow anchor holes, produce neat hole walls with minimal rock overbreak, raising finished stone yield rate for dimensional stone quarries.

Applications

Underground Coal Non Ferrous Metal Mine Anchor Support
Highway Railway Tunnel Shallow Peripheral Blast Holes
Hydropower Slope Anti Slide Anchor Municipal Foundation Reinforcement
Dimensional Stone Quarry Trimming Rock Splitting Pilot Holes
