## Summary description

DeWalt DT9420 drill bit designed for use with rotary hammers. Core specifications: diameter 22 mm, overall length 540 mm, single-piece supply. Intended for drilling into concrete and masonry where a rotary hammer is required. Suitable for construction and renovation tasks that need deeper, larger-diameter holes with SDS-compatible hammering action.

## Long description

DeWalt DT9420 drill bit for rotary hammer, Ø 22 mm and overall length 540 mm, is designed for drilling larger-diameter, deep holes in concrete and masonry. The bit features a solid two-cutter carbide tip with two additional cutting tips for fast, efficient penetration and a four-flute helix that clears debris to maintain cutting speed. Supplied as a single piece and compatible with SDS Max rotary hammers, this drill bit is intended for construction and renovation tasks requiring reliable performance when creating larger openings.
Advantages
The carbide multi-cutter tip design delivers improved drilling speed and durability compared with standard single-point bits. The four-flute helix provides efficient dust and debris evacuation, reducing clogging and heat buildup during prolonged use. SDS Max shank ensures secure tool engagement and straightforward bit changes in compatible rotary hammers. The 540 mm overall length allows reaching deeper drilling depths without extension accessories.
Suitable for
 Drilling deep holes in concrete and reinforced concrete
 Masonry drilling for anchor installation and through-holes
 Construction and renovation works requiring larger diameter holes
 Use with SDS Max rotary hammers for hammer drilling applications
Key specifications
 Drill diameter: 22 mm
 Overall length: 540 mm
 Tip material: carbide multi-cutter tip with additional cutting tips
 Flute design: four-flute helix for debris removal
 Shank type: SDS Max compatibility
 Quantity: 1 piece
 Typical application: concrete and masonry drilling
How to use
Select an SDS Max-compatible rotary hammer and secure the DeWalt DT9420 by inserting the shank until it locks. Mark the drilling position and start at low speed or with pilot pressure to establish the hole, then apply steady pressure and the hammer function to advance. Use intermittent drilling and withdraw the bit periodically to clear dust, or allow the four-flute helix to remove debris as you progress. Maintain a firm, controlled grip and avoid excessive lateral force to preserve tip life and prevent bit breakage.
Usage recommendations
For best performance and tool life, use appropriate personal protective equipment (eye protection, dust mask, hearing protection), operate the rotary hammer within the manufacturer’s recommended speed and impact settings for 22 mm bits, and let the bit cool by pausing periodically during extended drilling. Inspect the carbide tip before use and replace the bit when cutting efficiency or tip integrity is reduced.
