►The drill bit types and characteristics
1.1 high-speed steel drill bit (ordinary drill)
The main system uses high-speed steel W, Mo-based material
1.2, (alloy drill)
Tungsten titanium-based (YG), tungsten, titanium cobalt (YT) material.
Physical and mechanical properties of high-speed steel
and carbide materials
Carbide drill characteristics: high hardness, fast thermal conductivity , good toughness, good elasticity,
Carbide drill drawbacks: poor impact strength, abrasion resistance is poor.
The high-speed steel twist drill and carbide drill bit of the advantages and disadvantages are opposite.
