Dewalt SDS+ Drill Bit-14mm X 350mm X 300mm

Diameter: 14 mm; Overall length: 350 mm; Drilling depth: 300 mm. It has a 4-cutter head, precision-ground carbide tip, milled grooves for dust removal, a heavy-duty steel shank, and patented Super Lock technology with a dynamic 30° angle for improved torque transmission and safety.

Advantages include a 4-cutter design for faster material removal, a carbide tip for longer life, milled grooves for efficient dust removal, and Super Lock technology for better torque transfer. Comparable alternatives on Fepy include Makita 14mm SDS+ bit (https://fepy.com/product/makita-sds-plus-drill-bit-14mm-350mm) and Bosch 14mm SDS+ bit (https://fepy.com/product/bosch-sds-plus-drill-bit-14mm-350mm).

Concrete, brick, stone, and tile are suitable targets. It’s also capable of creating large anchoring holes and precise bore sizes in these materials.

Use it with an SDS+ hammer drill in hammer mode. Start at a modest speed and gradually accelerate, applying steady, moderate pressure. Let the bit do the work, keep it cool with adequate dust extraction, and avoid forcing the drill to prevent bit wear.

Keep cutting edges clear of dust, clean after use, and store in a dry place. Avoid overheating by using appropriate drilling speeds and letting the bit cool between heavy cuts.

Wear eye protection and gloves, ensure the drill is in SDS+ hammer mode, and keep hands away from the rotating bit. Check the bit for cracks or damage before use and secure the workpiece to prevent movement.

Ideal for professional installations and DIY projects that require large-diameter holes in concrete, brick, stone, or tile—such as anchor placements, conduit or pipe runs, electrical boxes, and plumbing penetrations.

Yes. The carbide tip and heavy-duty steel construction, along with the 4-cutter head and Super Lock technology, provide longer life and faster drilling, delivering efficiency and reliability for professional use.

Yes. You can explore other sizes in the same line to match your project needs. For related options, see: Makita 14mm SDS+ bit (https://fepy.com/product/makita-sds-plus-drill-bit-14mm-350mm) and Bosch 14mm SDS+ bit (https://fepy.com/product/bosch-sds-plus-drill-bit-14mm-350mm).

Look for a dull edge, slower drilling performance, increased resistance, smoking, or visible wear on the cutting edges. If performance drops significantly, it’s time to replace the bit.

The bit is specified for a 300 mm drilling depth. Use depth stops or guides to ensure you don’t drill beyond the intended depth, maintaining accuracy and reducing wear.
