What is the strongest metal for drill bits?
Cobalt (HSCO) is considered an upgrade from HSS because it includes 5-8% Cobalt blended into the base material. This is a great option for drilling into harder steel as well as stainless steel grades. Carbide (Carb) is the hardest and most brittle of the drill bit materials.Aug 4, 2021
When should you use a titanium drill bit?
Titanium-coated drill bits have reduced friction, require less effort and last longer than black oxide-coated bits. These are best for hardwood, softwood, PVC, fiberglass and steel. Cobalt drill bits are used for drilling hard metal and steel.
What is the advantage of cobalt drill bits?
Cobalt drill bits are incredibly strong. They can be operated at much higher speeds than a standard HSS drill bit. The ability to withstand heat means that cobalt bits perform for long periods without cooling or the need for cutting fluid. They are most often used to cut through hardened and abrasive materials.
What is the difference between titanium and cobalt?
The key difference between cobalt and titanium is in their appearance; cobalt is a hard, lustrous bluish-gray metal whereas the titanium is a silvery gray-white metal. Both cobalt and titanium are metals in the d-block.
