Reciprocating saw Makita DJR187Z, 18V Li-Ion, stroke 32 mm, stroke rate 2,300–3,000 spm, cutting depth wood 255 mm, metal 130 mm

The Makita DJR187Z reciprocating saw is a cordless, battery-powered tool designed for general cutting tasks in construction, renovation and maintenance. It combines an 18 V Lithium-Ion power system with a compact build and a 3.2 cm stroke length to deliver controlled, efficient cutting action across wood, plastic and metal when fitted with the appropriate blade. With a maximum no-load stroke rate of 3000 spm and an overall weight of 3.8 kg, the tool balances cutting speed and portability for on-site and workshop use.

Advantages

The saw offers cordless convenience with the mobility of an 18 V battery system and the sustained performance of Lithium-Ion technology. A 3.2 cm stroke length and up to 3000 strokes per minute provide a combination of reach and speed for aggressive cuts as well as finer work when required. At 3.8 kg the tool remains easy to handle for extended periods, and its measured vibration emission of 16.5 m/s² contributes to reduced operator fatigue during repetitive cutting tasks.

Suitable for

• Demolition and remodeling cuts in timber and plasterboard
• Plumbing and electrical access openings in walls and floors
• Metal pipe and conduit cutting with appropriate blades
• Pruning and removal of small tree branches and shrubbery
• On-site trimming and fitting of materials in confined spaces

How to use

Fit a blade suitable for the material to be cut and secure it according to the tool’s blade-clamping method. Ensure the battery is fully charged and inserted correctly before operation. Hold the saw with both hands, align the blade with the cut line, and apply steady forward pressure; allow the tool’s stroke rate and stroke length to perform the cutting action rather than forcing the blade. For controlled starts, momentarily engage the trigger at low pressure to align the blade, then increase speed as needed. After cutting, release the trigger, allow the blade to stop, remove the battery when changing blades or performing maintenance, and inspect the blade for wear before next use.

Recommendations

Use blades designed for the specific material (wood, metal, or combination) and match blade length to the workpiece thickness. Wear appropriate personal protective equipment such as eye protection, gloves and hearing protection. For prolonged cutting operations, plan brief pauses to check blade condition and reduce heat buildup. Store and charge batteries according to manufacturer guidance to maintain battery life and performance.
