Drill bit DeWalt DT9603-QZ, rotary hammer, diameter 22 mm, length 300 mm, 1 pc

DeWalt DT9603-QZ drill bit for rotary hammers, single piece with 22 mm diameter and 300 mm length. Engineered for impact drilling in masonry and concrete, this SDS‑Plus shank bit offers an extended working length to reach deeper anchoring points and pass-through holes. It is compatible with SDS‑Plus rotary hammer tools and intended for professional and DIY installation tasks that require reliable drilling performance under percussion action.

Advantages

The solid carbide tip and flute geometry provide efficient dust removal and consistent cutting performance during hammer drilling in hard substrates. The 300 mm overall length allows drilling deeper holes without the need for extensions, while the SDS‑Plus connection ensures quick, secure bit changes and stable power transfer from the rotary hammer. Supplied as a single unit, the bit is ready for immediate use and suitable for jobs where precision and repeatability are needed.

Suitable for (tasks / use cases)

• Drilling anchor and fixing holes in concrete and masonry
• Creating through-holes for piping or wiring
• Installation of bolts, sleeves and dowels at medium to deep depths
• General construction and renovation drilling with SDS‑Plus rotary hammers

Key specifications

• Diameter: 22 mm
• Overall length: 300 mm
• Shank type: SDS‑Plus
• Suitable material: concrete and masonry
• Quantity: 1 piece

How to use

Insert the SDS‑Plus shank into the chuck of a compatible rotary hammer and ensure it locks securely before starting. Select the hammer drilling mode on the tool and apply steady, moderate pressure while keeping the bit perpendicular to the work surface. Withdraw the bit periodically to clear dust from the hole and allow cooling. For through-holes, drill from both sides when possible to improve hole quality and alignment.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, hearing protection and dust mask. Match the drill bit diameter to the anchor or sleeve manufacturer’s recommendation and avoid excessive side loads to prevent premature wear. For best results in reinforced concrete, consider using a pilot hole or appropriate carbide-tipped masonry bits and maintain regular inspection of the bit for wear.
