Dewalt SDS+ Drill Bit-22mm X 250mm X 300mm

This is a 22 mm SDS+ drill bit designed to fit DeWalt SDS+ rotary hammer drills. It’s intended for heavy-duty drilling through masonry and concrete, with a flute length of 250 mm and an overall length of 300 mm for extended reach and stability.

Diameter: 22 mm. Flute length: 250 mm. Overall length: 300 mm. Material: hardened steel for durability. Shank: 300 mm for secure attachment to SDS+ chucks on compatible rotary hammers.

Ensure your drill is an SDS+ rotary hammer. Clean the bit and the chuck, insert the 22 mm bit into the SDS+ chuck, and firmly lock it in place. Use hammer action and drilling with steady pressure. Start at a modest speed, then increase as needed, and avoid forcing the bit through hard materials to reduce wear.

It's optimized for drilling through masonry and concrete. The hardened steel construction helps with durability during heavy-duty drilling tasks in these materials.

Wear eye protection, hearing protection, and gloves. Secure the workpiece, keep hands away from the rotating bit, and avoid overheating by drilling in moderate bursts and letting the tool shed heat between passes.

Clean off dust and debris after use, dry thoroughly to prevent corrosion, and store in a protective case or sleeve to prevent nicks or bendings. Inspect the bit for any cracks or dull edges before reuse.

If you notice visible wear such as a dulled or chipped cutting edge, reduced drilling performance, or excessive wobble in the chuck, it’s time to replace the bit to maintain accuracy and avoid damage to your drill.

Ideal for drilling holes in concrete or masonry walls where anchor fittings or fasteners are required, such as mounting heavy fixtures, running wiring, or creating anchoring points in reinforced or unreinforced concrete.

DeWalt is known for rugged, durable tooling and reliable performance in demanding jobs. The bit’s hardened steel construction and 300 mm shank provide secure attachment and long service life for frequent heavy-duty drilling in concrete and masonry.

Yes. With a flute length of 250 mm, the effective drilling depth is around that length, plus some margin depending on bit geometry and drill speed. For deeper holes, you may need to reorient or use multiple passes with appropriate pauses to manage heat.
