Many people see drill bits and think they are carbide or tungsten drill bits, but how do you know? On carbide drill bits (tungsten is what makes up the bit), they will often be marked CARBIDE. They have a much denser feel than normal steel drill bits.
Where will you find them? Glad you asked! Many machine shops will use these drill bits and tips for cutting blades because they can cut better and longer. Their pricing can be anywhere from $5 to 11 per pound, depending on which type you have, how much weight, and the consistency.
You’ll often find Carbide tips on grinding tools that bore and break rocks out of the ground too.
