Makita HP1640KX3 Percussion Impact Drill 16mm 680W - 74 Pcs/Set

Key specs include a 680W motor, a 5/8 inch (16 mm) chuck, percussion hammering for masonry drilling, 2800 RPM, a compact and lightweight design, an ergonomic soft-grip handle, a keyless chuck for quick bit changes, a rotating brush system for consistent power in forward and reverse, a 74-piece bit set, and a durable carrying case.

It's well suited for a range of tasks, including carpentry and woodworking, metal fabrication, and masonry work such as drilling into concrete or brick. The percussion function helps tackle tougher materials, making it a flexible tool for DIY enthusiasts and professionals.

To change bits, grip the chuck with one hand and rotate the outer sleeve of the keyless chuck to open it. Align the desired bit with the spindle, push it in fully, and tighten by releasing the sleeve so the bit is securely clamped. Ensure the drill is unplugged or powered off before changing bits.

The drill offers a percussion (hammer) mode for masonry and concrete. Use percussion when drilling into concrete, brick, or stone, and switch to standard drilling for wood and metal. Always start with a slower speed and appropriate bit, then increase as needed.

Wear eye protection and hearing protection, secure your workpiece, use the correct bit for the material, avoid forcing the drill and let the bit do the work, keep hands away from the rotating bit, tie back long hair, and unplug the drill when changing bits or making adjustments.

Clean the tool after use, remove debris from the chuck area, inspect the bit set for wear, store the drill and bits in the supplied carrying case to prevent damage, and avoid exposing the tool to moisture or extreme temperatures.

Use the percussion mode only when needed for masonry, avoid overloading the drill by feeding bits steadily, keep the bit and chuck clean, use sharp bits, and let the tool cool during extended tasks. Regularly inspect the power cord and chuck for wear and store in the provided case.
