Covered by a lifetime Lithium Ion tool , The NP18DSALQ4 (Tool body only) pin nailer features brushless motor technology that delivers more power to the motor by minimizing unnecessary energy loss through friction and heat. Managed by a micro-processor chip that efficiently delivers current flow to the motor. Brushless tools experience longer run time between charges, increased power, and extended durability with essentially No maintenance. The tool body makes it extremely well-balanced and comfortable for extended use. Available as a tool body only. This 23-gauge cordless pin nailer drives pins from 5/8" To 1-3/8" In length. Please note, it is necessary to buy high quality pins to ensure the tool works as expected. Pins with lower grade metal can be less rigid and bend at the point of entry or bend at the point of impact from the tool. Each of these scenarios can cause the tool to jam or the pin not to penetrate the wood as anticipated, especially at longer lengths. Metabo HPT pin nails are manufactured to higher tolerances and perform better in our nailers. For best performance, use the following genuine Metabo HPT pins, available on . 1) 23000SHPT (5/8") 2) 23001SHPT (3/4") 3) 23002SHPT (1") 4) 23003SHPT (1 3/16") 5) 23004SHPT (1 3/8") Can be used to produce nearly invisible holes for a variety of applications including cabinets, paneling, small molding and trim, glazed bead, craft work and picture frame Assembly
