And it is the only reason why a decision tree can perform so well. Therefore, node splitting is a key concept that everyone should know.

What is better 118-degree or 135-degree drill bits?

What kind of angle on a drill bit is best for drilling into harder materials?
For hard materials such as steel and stainless, 135-degree bits are best. The shallow angle allows the bit to cut into the material without dulling quickly, however that same shallow angle makes for a bit that wants to walk around, requiring a center punch.

No "walking" will occur when using a spade point, though the shaft of the bit has no spurs, so expect some snags where you need to manually clean debris out of the hole. Another alternative is a screw-tip bit, which will clear debris as efficiently as a split-point with its three shaft grooves.
