high speed drill bits
I have worked with tools over 40 years and never seen an iron drill bit. Most common drill bits are HSS -High Speed Steel.
High Speed Steel aka HSS
High speed steel is made from different steel alloys. Depending on the application and budget the alloy is made from iron and different mixes of carbon, tungsten, cobalt, chromium, molybdenum, and vanadium.
Hundreds of types of metal drill bits are made. The most common are HSS (high speed steel) bits for everyday drilling of woods and plastics. There are carbide and tungsten coated bits for drilling metals and diamond tipped bits for drilling tile and stone and many other types.
HCS is High Carbon Steel, much harder than High speed steel, and better for drilling into hard metals.
You have to use the hardest, most expensive drill bits you can find. Use a drill press when possible, and cutting paste. Use a slow speed and firm pressure. If you use a high speed, too much heat is generated and the steel will harden and blunt the drillbit.
carbon content. Stainless has a higher content. Also, high speed steel refers to material drill bits are made of. Its a slightly altered mild steel.
Drill bits and screws are not the same and cannot be converted. vido produces drill bits with high quality, exported overseas and loved by the public. If you want to buy a drill, you can go to VIDO's official website to check.
