Drill bit DeWalt DT9605-QZ, diameter 22 mm, length 600 mm, for rotary hammer

DeWalt DT9605-QZ single drill bit for rotary hammer applications. With a 22 mm diameter and 600 mm overall length, this long masonry bit is intended for deep drilling in concrete, brick and similar substrates. It is supplied as an individual replacement or spare bit and is designed to maintain consistent bore diameter during extended reach drilling operations.

Advantages

The solid construction and geometry of the bit provide reliable material removal and extended service life under heavy-duty use. Its 22 mm cutting diameter and long 600 mm length combine to enable deep, accurate holes while reducing the need for multiple extensions. The bit is compatible with common rotary hammer chucks and is suitable for use as a direct replacement, ensuring consistent drilling performance.

Suitable for

• Drilling deep anchor and through holes in concrete and masonry
• Installing long threaded rods or rebar dowels
• Electrical and plumbing penetrations through walls and slabs
• Replacement of worn or broken long masonry bits

Key specifications

• Shank type: suitable for rotary hammer tool chucks (SDS-plus/SDS-max compatibility depends on tool — verify before use)
• Drill diameter: 22 mm
• Overall length: 600 mm
• Material suitability: concrete, brick, block and similar masonry materials
• Intended use: hammer drilling with rotary hammers

How to use

Install the bit into the rotary hammer following the tool manufacturer’s instructions and ensure secure retention in the chuck. Select the hammer drilling mode and start at low speed to establish the pilot. Apply steady, moderate pressure and allow the tool to do the cutting; avoid excessive lateral forces that can damage the bit. Withdraw periodically to clear dust and prevent clogging when drilling deep holes. After use, inspect the cutting tip and shaft for wear and store the bit in a dry place.

Usage recommendations

Use appropriate personal protective equipment, including eye and ear protection and a dust mask or extraction when drilling masonry. Confirm shank compatibility with your rotary hammer model before operation and avoid using the bit in reinforced concrete with rebar contact unless specifically rated for that application.
