Capable of driving nails up to 90mm in length, offering performance comparable to that of a pneumatic nailer. Designed for versatility, it supports nails ranging from 50mm to 90mm in length and 2.9mm to 3.8mm in gauge. Users can switch between full sequential actuation mode for precise single shots and contact actuation mode for efficient continuous nailing. An integrated anti-dry fire mechanism activates before the magazine is empty, helping prevent missed shots and ensuring consistent operation. The DBN901 is available in two configurations: the DBN901ZK body-only version with a plastic case, and the DBN901RTE kit version, which includes two BL1850B batteries, a DC18RC charger, and a plastic case for convenience.
