For keyed chucks (HP1640/HP1640F) insert the bit fully, hand-tighten the chuck then use the chuck key in all three holes evenly. For sleeve-type chucks (HP1641/HP1641F) turn the sleeve to open, insert the bit, then tighten by turning the sleeve clockwise.

Product Description
Makita HP1640K Electric Percussion Drill incl. Case Manual
The Makita HP1640K Electric Percussion Drill incl. Case Manual introduces a compact, versatile corded percussion drill designed for both trade and DIY use. Built around a 1.8 kg body and a 303 mm overall length, the HP1640K family (HP1640/HP1640F/HP1641/HP1641F) delivers variable speed control (0–2,800 min–1) and high-impact rates (up to 44,800 bpm) for efficient drilling in masonry, concrete and stone while offering rotation-only mode for wood, metal, ceramic and plastic.
This drill emphasizes practical features: a variable-pressure trigger with lock-on function for continuous operation, reversing switch for screwdriving or clearing stuck bits, and a mode-change lever to switch between hammering and plain drilling. Some models include an integrated lamp for low-light tasks. The tool accepts tungsten-carbide tipped bits for hammer drilling and supports both keyed and keyless chuck systems depending on the model variant. A side auxiliary handle and a depth gauge improve control and repeatable hole depths, and an optional blow-out bulb aids hole cleaning.
Safety and durability are central to the manual: the HP1640K is double-insulated for safe use on single-phase AC supplies and designed to European safety class a/II. The manual highlights specific safety rules — use ear protection, always fit the auxiliary handle, hold the tool by insulated surfaces when electrical hazards are possible, maintain stable footing, and avoid excessive pressure that damages bits and the tool. Maintenance guidance stresses disconnecting power before inspection and recommends Makita authorized service centers for repairs and carbon brush replacement.
Accessories and kit contents typically include a plastic carrying case, chuck key or keyless chuck, auxiliary handle, depth gauge, blow-out bulb, safety goggles and a selection of compatible bits and hole saws. Practical operation tips cover bit installation and removal (both keyed and sleeve-type chucks), setting the depth gauge, and best practices for drilling in wood (use guide-screw bits), metal (center-punch and cutting lubricant), and masonry (light pressure, intermittently clear debris).
Overall, the Makita HP1640K is presented as a reliable, easy-to-handle percussion drill suited to varied drilling tasks, combining ergonomics, power control and safety features in a portable kit with a carrying case.
