Holesaws can be very expensive but this great kit fromBlue Spot make life very easy for not a great dealof money. While we do not recommend it for the trade and daily use, for the occasionalhole needed by the home improver it is ideal. It will drillholes through timber upto 20mm thick and in sheet metal 2 or 3mmthick.It will also drillholes through plastic. A great set from Blue Spot.
