The DTH hammer operates through compressed air, which is pumped through a series of valves and chambers within the hammer. When the air pressure builds up, it drives a piston that strikes the drill bit, creating a powerful force that breaks the material. This process continues in rapid succession, allowing the drill bit to penetrate the ground efficiently. The design of the DTH hammer allows for a larger drop height of the piston than traditional rotary drills, resulting in higher impact energy and better drilling performance.

  • Moreover, using a rack helps with cleanup. When drippings or juices from marinated meats or roasted vegetables fall, they can pool around the bottom of the sheet pan. By elevating the pan, the rack allows these liquids to drain away, keeping your food cleaner and making subsequent cleaning much easier. Additionally, it prevents food from steaming rather than roasting, which is crucial for achieving that perfect caramelization and flavor intensity.
