Review on IRWIN 29-Piece Titanium Nitride Coated Tool Set (3018003) by John Murphy

These bits are exactly what I've come to expect from Irwin: sharp, straight and durable. However, the case was disappointing. Some bits are too tight, but the three smallest bits fall out of their sockets when the case is closed. A cheap looking cardboard sheet with drilling and threading information covers the bottom of the case to hide the melting points used to attach the outer plastic. I purchased a Huot metal drill bit index for bit sizes from 1/16" to 1/2" in 1/64 increments to ensure proper bit placement.
