  We usually call high-speed steel high-speed tool steel or front steel, but the most common name is white steel. Because high-speed steel has better processing properties, and its strength and toughness are also very good, it is mainly used to manufacture complex thin-walled and impact steel. Corrosion-resistant metal cutting tools, such as HSS cobalt drill bit .

  However, these characteristics also facilitate its use in the manufacture of high-temperature bearings and cold extrusion dies. HSS cobalt drills are also alloy drills. General tool steel is also alloy steel, but only iron-carbon alloys. High-speed steel needs to be further divided into ordinary high-speed steel and high-quality high-speed steel. Therefore, the current alloy drills usually refer to cemented carbide drills.

  When we are grinding HSS cobalt drill high-speed steel, when 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 the entire side. After cutting into the drill bit, you can touch the grinding wheel lightly, perform a small amount of grinding first, pay attention to the uniformity of the spark, adjust the pressure on the hand in time, and pay attention to cooling the bit and performing edge annealing. When the temperature of the cutting edge is high, please cool down the drill in time.

  Different from HSS cobalt bit high-speed steel,  wood auger drill bit has a long history and still exists today. Since wood auger drill bit has not been eliminated by history, then they must have their own advantages to occupy a place in the market.
