Down-the-hole hammer drilling is a technique used primarily for drilling boreholes in hard rock applications. It employs a pneumatic hammer, situated directly at the drill bit, to deliver high-impact blows that effectively break up the rock. This method contrasts with traditional rotary drilling, where the drill bit operates at the surface and relies on torque and weight to penetrate the ground.

Jaw plates are commonly made from manganese steel, an alloy that boasts high wear resistance and toughness. Manganese steel typically contains between 11% to 14% manganese, which contributes to its unique and advantageous properties. The addition of manganese enhances the alloy's hardenability, allowing it to become exceptionally hard when subjected to heavy impacts. This characteristic makes manganese steel an ideal choice for high-stress applications, such as crushing abrasive materials in mining.
