DeWalt DT9558-QZ 12mm x 600mm Extreme SDS PLUS 2-cutter Drill Bit
DeWalt DT9558-QZ Extreme SDS Plus Drill Bit (12mm x 600mm, 2-cutter)
DeWalt DT9558-QZ is a 12mm SDS Plus masonry drill bit designed for fast, controlled drilling into concrete and other hard building materials when used with an SDS+ rotary hammer.
With an extended 600mm overall length and a 550mm working length, the DT9558-QZ is suited to deeper holes where reach matters, while the helix design helps move dust and debris away from the cutting area for smoother progress.
Key Features
- SDS Plus shank: Designed to fit SDS+ rotary hammers for positive engagement and efficient power transfer.
- 2-cutter carbide head: Built for effective penetration and consistent drilling performance in masonry materials.
- Four-flute spiral: Helps clear drilling dust and debris quickly to maintain drilling speed.
- 2-stage helix: Optimised flute geometry supports effective dust removal and improved drilling performance.
- Tough Core design: Increased core material helps improve durability during demanding drilling tasks.
- Iron Blast Technology: Strengthens the bit body to help reduce the risk of breakage.
- Anchor wear mark: Visual indicator to help show when the bit should be changed for mechanical anchor installation.
