Drill bit Makita D-17566, single-piece pack, for general drilling use

Makita D-17566 is a single-piece drill bit sold as one unit per pack, designed for general drilling tasks with SDS-PLUS rotary hammers. Engineered with a tungsten carbide tip and a two-cutter head, this replacement accessory provides a durable cutting edge for drilling into concrete and similar masonry materials. The shank and flute design are compatible with SDS-PLUS chucks, allowing quick bit changes and stable operation during light construction, renovation, and repair work.

Advantages

The tungsten carbide tip offers improved wear resistance and maintains cutting performance when drilling into abrasive masonry materials. The two-cutter head produces a balanced drilling action that helps reduce wandering at the start of a hole and supports efficient dust removal through the flutes. Compatibility with SDS-PLUS hammers ensures secure retention and rapid bit replacement, making the product convenient for both professionals and DIY users needing an individual spare bit.

How to use

Insert the SDS-PLUS shank of the Makita D-17566 into the drill chuck according to the hammer drill manufacturer’s instructions until it locks in place. Select the appropriate drilling mode and speed for masonry; start drilling with steady pressure and allow the bit to work without excessive force. Periodically withdraw the bit to clear dust from the hole and flutes. For deeper holes, withdraw more frequently to improve debris removal and prevent overheating of the carbide tip.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, hearing protection and dust mask when drilling. Match drill speed and hammer action settings to the material being drilled and avoid excessive lateral force to prolong bit life. Replace the bit if the carbide tip shows significant wear or chipping to maintain drilling efficiency and safety.
