Drill bit DeWalt DT9519 SDS-EX2 6.5 x 110/50 mm

DeWalt DT9519 SDS-EX2 6.5 x 110/50 mm is an SDS-Plus rotary hammer drill bit designed for impact drilling in masonry and concrete. The bit features a solid carbide tip and reinforced shank construction to provide accurate hole positioning and improved wear resistance during repetitive drilling tasks. Its length and working section are sized for installing anchors, dowels and through-holes where stable, reliable performance with SDS-Plus hammer systems is required.

Advantages

The carbide tip ensures sharp cutting edges that maintain drilling speed and reduce chipping in abrasive materials. Reinforced shank construction improves the bit's resistance to breakage and deformation under high-impact loads. Optimized flute design evacuates dust efficiently, helping to keep drilling progress steady and reduce overheating. The geometry is balanced to provide straight, precise holes and minimize walking at the start of drilling.

Suitable for

• Drilling holes in concrete for anchors and dowels
• Through-holes in masonry and block work
• Preparation of fixing points for mechanical fasteners and rebar dowels

Key specifications

• Shank type: SDS-Plus compatible
• Tip material: solid carbide
• Drill diameter: 6.5 mm
• Total length: 110 mm
• Working length: 50 mm
• Intended materials: concrete, masonry, blocks

How to use

Fit the SDS-Plus shank securely into the rotary hammer chuck following the tool manufacturer's instructions. Use the rotary hammer in hammer mode for impact drilling; apply steady axial pressure without forcing the bit. Begin drilling at low speed to establish a straight start, then increase speed as the bit advances. Periodically withdraw the bit to clear dust from the hole and allow the flute to evacuate debris for consistent performance. For deeper holes, repeat clearing strokes more frequently.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling. Use a drill setting suitable for SDS-Plus bits and choose drilling speed and pressure according to material hardness. Replace the bit when the carbide tip shows excessive wear or when drilling time increases noticeably to maintain hole quality and safety.
