Drill bit DeWalt DT9515 6 mm x 160 mm for rotary hammer, 1 pc

DeWalt DT9515 6 mm x 160 mm drill bit is a single-piece accessory engineered for use with rotary hammers to drill holes in concrete, masonry and similar hard substrates. The 6 mm diameter and 160 mm overall length make it suitable for common repair and installation tasks where precise, through or depth-limited holes are required. A carbide tip and spiral flute geometry deliver consistent cutting action and efficient removal of dust and debris during drilling.

Advantages

The carbide tip provides durable cutting performance and improved wear resistance compared with standard steel bits, extending service life when drilling abrasive materials. The spiral flute design enhances chip evacuation to reduce clogging and maintain drilling speed. The single-piece construction improves stability and reduces breakage risk under rotary hammer loads. The bit’s dimensions balance reach and rigidity for controlled drilling in confined or overhead positions.

Suitable for

• Drilling holes in concrete for anchors and plugs
• Creating openings in brick and masonry for installations
• Preparation work for electrical and plumbing conduits
• General repair and renovation tasks that require small-diameter holes

Key specifications

• Diameter: 6 mm
• Overall length: 160 mm
• Tip material: carbide
• Flute type: spiral flute for chip evacuation
• Construction: single-piece design for increased stability
• Intended tool type: rotary hammer

How to use

Select a compatible rotary hammer and set it to the appropriate hammer drilling mode. Secure the drill bit in the tool’s chuck or SDS holder according to the tool manufacturer’s instructions, ensuring the bit is fully seated. Mark the drilling position, apply steady axial pressure, and start drilling at low speed to establish the hole, then increase speed as required. Withdraw the bit periodically to clear debris if drilling deep holes, and avoid excessive side load or bending. Allow the carbide tip to cool between prolonged drilling sessions to preserve cutting performance.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection and dust mask. For best results in concrete and masonry, use the drill bit with a rotary hammer set to a hammering drilling mode and match the bit diameter to the recommended anchor or plug size.
