Review on Enhanced Neiko 10181A Titanium Grooved 3-Piece Set by Matthew Mosley

I love Neiko's Titanium Coated Quick Change Spiral Flute Step Drill. I tried the non-spiral version of these drill bits and it didn't work for my project, but they allowed me to drill a perfectly sized hole in plastic cups with just an electric screwdriver. Wonderful. I saved a fortune on expensive planters by using regular cups which are very difficult to pierce. The tips are so sharp I didn't even have to drill a pilot hole. I am thrilled and highly recommend them1
