Online tutoring has been famous for quite some time now. It's an interesting concept because it works wonders breaking down the language barrier by helping non-English speakers learn the language through native speakers. It allows easy-access for homeschooling for people who cannot go to school and it allows people to share their own set of skills with another. Here's how you can earn money while sharing your skills with others. Read more http://www.make-lots-of-money.com/make-money-tutoring-online/

Officials have launched a manhunt for the absconders, with police glance all roads in the Arcadins coastal zone near Arcahaie prison.

Tunnel boring machine cutters referred to as "TBM Cutters", are excavation tools installed on the cutter heads of tunnel boring machines and shield machines, which include TBM disc cutters (single disc cutter, double disc cutter, twin disc cutter) and soft ground cutters (eg. scrapers, cutting knives, buckets, rippers and other cutting tools). These types of disc cutters and soft rock cutters, in different sizes and specifications, can also be used on MTBM, pipe jacking machines, and other similar rock-breaking equipment.

Raise boring cutter (RBM cutter) is a tungsten carbide insert roller cutter mounted on the reaming head of raise boring machine (RBR, raise borer), which is an excavation tool for breaking rocks. As the most important raiseboring drilling tools, the raise boring cutters are mainly used in the construction of vertical shafts, inclined shafts, surge shafts, ventilation shafts, and escape shafts, and can be widely applied in underground engineering construction fields such as mine, hydropower, transportation and so on.

The construction of every tunnel excavation and underground project requires the coordinated operation of various types of equipment. Rock drilling tools & tunneling tools used in underground tunnel construction are crucial instruments for penetrating and breaking through rock layers. Choosing the right rock tools not only withstands the harsh conditions and high pressure encountered during tunnel construction but also significantly enhances the speed and safety of underground tunnel construction. This, in turn, shortens project timelines and improves cost-effectiveness.

Single disc cutter, also known as single disk, is a kind of disc cutter with only one cutter ring, which is mounted on the front and gauge area of the cutter head. It is mainly used as face cutter and gauge cutter to break hard rock with high uniaxial compressive strength (UCS≥70Mpa) and mixed ground. It is a key cutting tool for rock excavation.
