The sets consist of a palm handle, and either four or ten interchangeable blades, a pre-printed wooden blank and full instructions, all packed in a good quality tool roll. As a bonus, with the purchase of the 810480 Adaptor, you can use the chisels with the Bosch and Skil Power Carvers. 10 blade set includes: 3 x 3/8"(9mm), 3 x 5/8"(16mm), 5 x 9/16"(14mm), 6 x 5/16"(8mm), 9 x 1/16"(1.5mm), 11 x 1/8"(3mm), 11 x 1/4"(6mm) gouges, 45° x 1mm micro parting tool, 70° x 1/4"(6mm) vee tool and a 1 x 1/4"(6mm) chisel.Excellent for carvers whilst travellingPalm handlePre-printed wooden blankChisels can be used with Bosch Power Carver with a purchasable adaptor
