Steel: Steel is a common material used to make core barrels because it is strong, durable, and can withstand high temperatures and pressures.
Tungsten carbide: Tungsten carbide is a hard, wear-resistant material that is often used to make the cutting bits on core barrels.
Diamond: Diamond is the hardest material on Earth and is often used to make the cutting bits on core barrels that will be used in very hard or abrasive formations.
