It is the fastest pickaxe in the game. It deals 15 pickaxe hits per second without any modifiers, and 20 with the best modifier. It can mine almost every block in the game in 1 hit, with the exception of a few blocks. Mythril Ore, Orichalcum Ore, Adamantite Ore, Titanium Ore, and Wooden Spikes take 2 hits and Chlorophyte Ore takes 3. It chops any tree in 0.27 seconds without any modifiers, and 0.2 seconds with the best modifier. See also Mining Speed for a comparison of all mining tools in the game.
Its best modifier is Light for harvesting purposes and Legendary for combat purposes.
The post-Moon LordDrill Containment Unit is another viable alternative. Although it is slower when digging downwards and its speed cannot be buffed, it has infinite flight time and a greatly increased mining range.
Although it is a tool, it is a relatively viable melee weapon due to its very fast speed and high damage. The only shortcomings are its low range and knockback.
If any three effects that increase mining speed are used, such as a Light reforge, Mining armor, Mining Potion, Ancient Chisel, Celestial Shell, or Slice of Cake, the player will be able to mine 1 block every frame, or 60 blocks per second if the game is running at 60fps. This is because the digging claw's use time of 4 frames means every increase to mining speed will always reduce the use time by 1 frame. At this speed, it is possible to mine slightly faster than the player will fall, which can be dangerous without immunity to fall damage.
It has a low sell price compared to other tools of the same tier, making it relatively cheap to get a Light or Legendary modifier by reforging.
