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.
