DTH drilling refers to a method where the drilling bit is located at the end of a drill string, below the surface of the ground. This technique is distinguished by the use of high-performance percussion hammers, which are positioned on the drill bit. DTH drilling involves the use of compressed air to deliver rapid impacts, breaking rock into smaller fragments. This method is particularly effective in hard rock formations, making it a preferred choice for mining operations and various drilling applications.

  • The block is unlikely to distort except after severe overheating, but check anyway using a steel ruler or similar high-quality straight-edge.

  • Another way to test spark plug wires is by using a multimeter. This tool can measure the resistance of the wires to determine if they are still conducting electricity effectively. To do this, disconnect the spark plug wires from the spark plugs and the ignition coil. Set the multimeter to the resistance setting and touch the leads to the terminals of the wires. The resistance reading should be within the specified range for the wires to be considered in good condition.
  • Resistant to steam, petroleum oils, amine corrosion inhibitors, and hydrogen sulphide. 
  • Oil seals are a critical component in the operation of machinery, providing a vital barrier between the internal lubricated parts and the external environment. These seals prevent the leakage of oil, which is essential for the proper functioning of the machine's components. They also prevent contaminants from entering the system, maintaining the quality of the oil and ensuring its longevity.

  • Improved Performance and Fuel Efficiency

  • When it comes to maintaining the performance of your vehicle, one of the most important components to consider is the spark plug. The spark plug plays a crucial role in igniting the air-fuel mixture in your engine's combustion chamber, which in turn powers your vehicle. Among the various brands and types of spark plugs available in the market, Mico spark plugs are known for their quality and reliability.


  • Overall, E3 spark plugs are a top choice for drivers looking to improve their vehicle's performance, fuel efficiency, and emissions. With their innovative design, durable construction, and easy installation, E3 spark plugs offer a reliable and cost-effective solution for optimizing engine performance and extending the life of the vehicle.

  • In addition to their functional role, oil seals also contribute to the overall performance of the vehicle. By ensuring a consistent supply of lubricating oil, they help maintain the engine's smooth operation, reducing noise and vibration, and enhancing fuel efficiency.

  • Runout must be kept to a minimum. Movement of the center of rotation is usually caused by bearing wobble or shaft whip. When coupled with misalignment, this problem is compounded. Contrary to popular belief and common practice, the installation of flexible couplings cannot correct or compensate for misalignment.
