How do I get 10 MORE MINING SPEED

[HershyKid]

So when mining at Y level 65 in Crystal Hollows I get 1.49k mining speed litterally 10 away from being able to insta mine hardstone, I wanna know how to get more for cheap cuz I wasted all my money on a drill (that i dont use) and the flamebreaker that gives me a 60 mining speed (3/4 set + sorrow boots) HELPPPPP
