Snappy 7mm collected HSS drill bit
As a tradesman l find the Trend snappy system very convenient in the work shop. Having all the necessary drills, counter sinks and driver bits in one convenient case. The only downside is that after awhile the case elastic bindings holding the bits looses some of its tension and bits become loose and can fall out when in transit (a zip would be great). Hence the purchase of a replacement 7mm drill bit.
