Product information

Description

The DeWalt DT9447-QZ masonry drill bit is a 42 mm diameter bit designed for use with rotary hammer tools. Supplied as a single piece, this SDS Max shank drill bit is made for drilling holes in masonry materials including concrete, brick and stone. Its head design and flute geometry are intended to provide efficient debris evacuation and sustained drilling performance for larger-diameter anchor, plug or clearance holes.

Advantages

The bit features a solid two-cutter carbide tip flanked by two individual cutting tips to increase cutting efficiency and maintain drilling speed. A four-flute helix helps remove dust and debris from the hole, supporting steady progress during drilling. The shank and body are hardened to improve strength and reduce the risk of breakage, while the optimized mounting shank aims to provide secure grip and effective power transmission when used in compatible rotary hammers.

Suitable for

  • Drilling larger-diameter anchor or plug holes in concrete
  • Creating clearance holes in brick or block work
  • Drilling into natural stone and masonry for fixing and anchoring

Key specifications

  • Drill bit diameter: 42 mm
  • Overall length: 570 mm
  • Shank type: SDS Max
  • Tip: solid carbide multi-cutter head (two-cutter with two flanking cutting tips)
  • Flute design: four-flute helix for debris removal
  • Suitable materials: concrete, brick, block work, masonry, stone
  • Pack quantity: 1 piece

How to use

Install the SDS Max shank securely in a compatible rotary hammer according to the tool manufacturer’s instructions. Position the drill bit on the marked drilling point and apply steady pressure while operating the hammer function. Use appropriate drilling speed and intermittent withdrawal to clear dust and prevent overheating if drilling deep holes. Always allow the tool and bit to cool when performing multiple successive holes.

Usage recommendations

Wear appropriate personal protective equipment including safety glasses, hearing protection and dust mask. Use a vacuum or dust extraction system where possible to reduce airborne dust. Select an appropriate anchor or plug size for the 42 mm hole and inspect the bit for wear or damage before use.
