I'd like to preface this by describing my situation. In the marine industry, drilling sizable holes through thick metals isn't an uncommon occurrence. I've tried four different drill bit sets from Dewalt to fulfill my need for a bit that cuts immediately and lives on after a day's worth of constant, repeated drilling. I have looked no further after ordering the pilot point set. I can run the 1/2 bit for about 8 hours straight in a press drilling lt;50 holes through 1/8 thick galvanized steel. With cutting oil and and a lower drilling speed, I've found it very hard to destroy these bits. Their cost makes it easy for me to replace them every few months as buying individual bits is no cheaper than a set like this
