In addition to regular inspections, proper lubrication is also key to ensuring the longevity and effectiveness of gearbox seals

gearbox seals. Lubricants help reduce friction between moving parts, which in turn reduces wear and tear on the seals. It is important to use the right type and amount of lubricant for the gearbox to ensure that the seals remain properly sealed and functioning optimally.

Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.

Twist drills, with their helical cutting edges, became the standard for 75mm drill bits in the 1960s. These drills cut by shearing the material and ejecting it through the flutes, resulting in cleaner holes with less material buildup. The development of twist drills also led to the refinement of drill bit geometry, including the addition of secondary cutting edges and better chip evacuation channels The development of twist drills also led to the refinement of drill bit geometry, including the addition of secondary cutting edges and better chip evacuation channels
