Makita DBN901 18V LXT 21° Round-Head Framing Nailer

The Makita DBN901 is an 18 V cordless framing nailer from the LXT® system equipped with a brushless motor and an air-spring drive mechanism. This enables driving 50 – 90 mm round-head nails with performance comparable to pneumatic nailers, but without requiring hoses or air compressors. 

Primary application: Intended for first-fix framing work such as joists, battens, timber studs or roof structures where large-format nails (50 – 90 mm) are required. 
Operating principle: Utilises an air-spring mechanism accelerated by a brushless motor to drive nails. Features selectable actuation modes: full sequential actuation (single nail per trigger pull) or contact (bump) actuation for faster repetitive nailing. 

Key advantages:

• Cordless design means no compressor or hose needed, reducing tripping hazards and enabling quieter operation.

• Depth-adjustment dial allows precise control of nail penetration. 

• LED job-light with pre‐glow and after‐glow improves visibility in work zones. 

• Anti-dry fire mechanism stops the tool from firing when nail supply is nearly depleted, protecting the workpiece and drive pin. 

• Anti-slip nose tip improves grip when driving nails at an angle. 

Technical specifications:

• Nominal voltage: 18 V (LXT battery system) 

• Compatible nail length: 50 mm to 90 mm. 

• Compatible shank (diameter): Ø 2.9 – 3.8 mm for the round-head nails version. 

• Magazine capacity (nails): approximately 36 – 41 nails in the strip for this model. 

• Nail collation angle: 20°–22° (round-head version).

• Net weight: around 5.0-5.4 kg (depending on battery) for the tool body alone.

• Ensure the selected nails comply with lengths and diameters specified for this tool.

• Use only compatible Makita 18 V LXT® lithium-ion battery cartridges and chargers as listed in the manual. 

• Always wear appropriate personal protective equipment (PPE) including eye and ear protection when nailing.

• The tool is designed for framing and heavy-duty applications, not for fine finish-work or precision joinery where smaller fasteners are used.

• Regularly check and maintain the magazine, nose piece and ensure the depth dial is set correctly for the material being nailed.
