## Long description

DeWalt DT9578-QZ is a single 10 mm diameter drill bit with a 160 mm overall length, designed specifically for drilling into concrete and masonry.

Advantages
The drill bit provides accurate 10 mm holes with consistent depth control across repeated uses. Its length of 160 mm allows reaching deeper anchoring points while maintaining rigidity during drilling.

How to use
Mark the drilling point and set the drill to the suitable drilling mode (rotary or hammer) depending on your tool. Secure the work area and use appropriate personal protective equipment such as safety glasses and gloves. Insert the DeWalt DT9578-QZ bit into the drill chuck or SDS adapter and tighten. Start drilling at low speed to establish the hole, then increase speed and apply steady pressure until the required depth is reached. Withdraw the bit periodically to clear dust for cleaner holes and to prevent overheating.
Usage recommendations
Use the bit with a drill that supports hammer function for fastest results in concrete. For anchor installation, confirm the hole depth and clean the hole of dust before inserting plugs or anchors. Replace the bit when cutting performance decreases or when the tip shows visible wear to maintain hole accuracy.
