Review on Masonry Multipurpose Industrial Strength Triangle by Justin Verslues

Reading the description it turns out that these masonry drill bits have metric dimensions. This is not a problem when using conversion tables. The set varies from 3mm to 12mm or approximately 1/8" to 1/2". Of course, this extra step is a bit cumbersome for most of us. Therefore I deduct 1 star from the overall rating and has nothing to do with poor quality. I also like the triangular handle at the base of the bit. This virtually eliminates bit slippage while drilling.
