How should a new drill bit be treated when drilling hard materials?

When drilling hard materials, it's essential to apply pressure gradually to ensure that the drill bit engages effectively without risking damage. Starting with lower pressure allows the bit to cut into the material without overheating or becoming dull too quickly. As the bit begins to penetrate and the cutting process stabilizes, gradually increasing the pressure helps in maintaining the drilling operation's efficiency.

This approach is particularly important because hard materials require a careful balance of pressure to achieve precision and performance while avoiding the potential for the drill bit to bind or break. Applying too much pressure from the start can lead to excessive wear or overheating, which can harm the bit and reduce its lifespan. Therefore, the strategy of incrementally increasing pressure allows for a smoother and more controlled drilling process, optimizing the effectiveness of the tool as it works through hard materials.
