A quality Forstner set, perfect for clean and accurate holes in soft and hard wood. We have tested these heavily at Axminster and have found them to perform extremely well and represent excellent value for money, so much so we are proud to put our name on them. All Forstner bits are short pattern. The 10 and 12mm has a 8mm shank, 15 to 22mm is a 10mm shank, 25 to 35mm a 12mm shank and the 40 to 50 a 15mm shank. Metric sizes 10, 12, 15, 16, 18, 20, 22, 25, 26, 28, 30, 35, 40, 45 and 50mm. Includes a depth stop that fits sizes 15mm and up. For the best results, use in a pillar drill.
