FAMAG Drill countersink set 4 mm - 6mm with depth stop (for construction of terrace)

Countersink set with rotating depth stop (brass). Depth of pre-drill is adjustable. Countersink angle 60°. This set is particularly well suited for terrace construction. It makes it easy to drill screwholes and to countersink them properly and accurate in the terrace boards. The depth stop is rotatably mounted and stops when it touches the workpiece. This prevents the depth stop from leaving marks on the terrace boards. Adjust the depth so that the floor board is just perforated (board thickness). Thus, the self-tapping terrace screw can find a perfect hold state. Countersink/Pre-drill: alloyed tool steel. Depth Stop: brass. 1500 - 2200 rpm, e.g. recommended value aprox. 1800 rpm in hard wood
