Drill bit DeWalt DT9680-QZ, diameter 1.6 cm, single piece, 165 g

DeWalt DT9680-QZ is a single 16 mm diameter drill bit designed for use with compatible hand or power drills. Constructed for drilling into concrete and similar masonry materials, this single-piece bit features a 4-cutter carbide head and enhanced manufacturing processes that improve strength and chip removal. Supplied as one unit and weighing 165 g, the bit suits specific drilling applications that require a 16 mm hole size and straightforward replacement when worn.

Advantages

The DEWALT ELITE SERIES design uses high-speed composite blasting to harden the bit surface and lower the risk of breakage during heavy use. A tapered core increases the bit's toughness and resists flute fractures, while the 4-cutter carbide head delivers efficient cutting performance and consistent hole quality in concrete. The bit also includes an anchor wear mark to signal when replacement is required for safe anchor installation. Manufactured in Germany to controlled standards, the bit provides reliable, repeatable results for appropriate materials.

Suitable for

• Drilling 16 mm holes in concrete and masonry
• Installing mechanical anchors and fasteners where a 16 mm diameter is specified
• General-purpose masonry drilling with hammer drills or rotary hammer tools compatible with the bit shank
• Replacement of worn or damaged 16 mm drill bits in construction and renovation tasks

How to use

Select a drill or rotary hammer compatible with the bit shank and the drilling mode required for masonry. Secure the workpiece and mark the drilling position. Fit the 16 mm bit into the drill chuck according to the tool manufacturer's instructions, then apply steady pressure and use the hammering action if drilling into concrete. Withdraw the bit periodically to clear dust and debris from the hole and allow the bit to cool. Observe the anchor wear mark and replace the bit when the mark indicates excessive wear to maintain hole accuracy and fastening safety.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection, and dust extraction or a mask when drilling masonry. For best performance, match drill speed and hammer settings to the material; avoid excessive lateral force that can cause premature wear or flute breakage. Replace the bit when the anchor wear mark is reached or if the cutting performance noticeably declines.
