  Now the alloy drill bits on the market are generally made of tungsten steel monolithic drill bits. Although the material is the same, the product quality of each brand is very different due to the processing technology. Imported and domestic alloy drills are also very different. Therefore, domestic graduate students produced HSS cobalt drill bit . The biggest difference between high-speed steel drills and cobalt-containing drills is the amount of cobalt. The higher the cobalt content, the higher the quality! The HSS cobalt drill bit not only has the characteristics of high-speed steel drill hair, but also combines the characteristics of cobalt, and the quality is more advanced.

  So do you know how to grind HSS cobalt drill bits? After the cutting edge is in contact with the grinding wheel, we need to grind from the main cutting edge to the back, that is, the cutting edge of the drill starts to contact the grinding wheel, and then slowly grinds down the entire flank surface. When the drill bit is cut in, you can lightly touch the grinding wheel, first perform a smaller amount of sharpening, and pay attention to the uniformity of the sparks, adjust the pressure on the hand in time, and pay attention to the cooling of the drill bit. , And to the edge annealing. When the temperature of the cutting edge is found to be high, cool the bit in time.

  Know how to grind high-speed steel cobalt drill bits, do you know the history of wood drill bits?

  Woodworking is a craft, a unique technique, and a commonly used technique in construction. It is one of the three traditional Chinese lines (that is, woodworking, wood, and carpentry).

  It is said that houses were built in ancient times, and on the day the houses were built and capped, "woodworkers" must be hired to suppress evil!

  When suppressing evil, the woodworker took out his own tools and stood on the roof screaming for good luck, so as to protect the future safety and wealth! In today's society, "woodworking" has a wide range of professional applications.

  For example, in the field of housing construction, shipbuilding, landscape construction, and the most common decoration and decoration fields.

  It can be seen that the wood auger drill bit was a very popular item a long time ago. Since ancient times, wood drill bits have not been eliminated by history, and they must have their own merits.
