7° Coal Mining Shank 22 mm x 159 mm Rock Hex Rock Drill Rod
Description
Tapered equipment affords drillers the ability to change drilling bits whilst still using the same drilling rod. Different taper sizes have different characteristics when it comes to the “knock-off” index – the smaller angle will prevent the bit from spinning.
• Suitable for small hole range
• Widely used in Dimensional Stone Quarrying Industry
• Widely used in Underground Mining Industry
Color: Based on Customer requirements
Material: Tungsten carbide and high strength alloy steel
Processing: CNC milling and proprietary heat treatment process
Type: 7° Tapered Hex 22 Tapered Rod Shank 22 mm x 159 mm
Applications
• Underground Mining
• Tunneling
Why There are many different Taper?
Different taper angles are used for different rock formations and rock drills. A wide taper angle is normally used when drilling with high impact hydraulic rock drills in medium hard to hard and abrasive rock formations. Taper angles of 11°and 12° are common on modern rigs.
A narrow taper angle of 7°is used for low impact rock drills and softer rock formations. This angle can also be used if you have spinning problems when using 11° or 12° equipment.
In addition, a 4°46' angle is ideal for soft rock when you’re using pneumatic or hydraulic drill rigs – to prevent bits from spinning or becoming detached.
