Drill bit 6 mm x 260 mm for rotary hammer DeWalt DT8915-QZ, 1 pc

DeWalt 6 mm x 260 mm drill bit for rotary hammer is engineered for drilling precise holes in concrete, masonry and stone. The single-piece design with a 4-cutter carbide head and tapered core increases strength and reduces the risk of breakage during rotary hammer operation. Compatible with SDS-Plus chucks where applicable, this 260 mm length provides reach for deeper anchor and plug holes while the 6 mm diameter delivers accurate sizing for fasteners and anchors.

Advantages

The solid-piece carbide tip with four cutting faces offers improved penetration and reduces the likelihood of jamming when encountering rebar. A high-speed blasting process and a brazed carbide-to-body bond enhance durability and resistance to wear. The 4-flute helix clears debris efficiently, maintaining drilling speed and producing cleaner holes. The tapered core design increases overall bit strength and helps prevent flute breakage under impact loads.

Suitable for

• Drilling anchor and plug holes in concrete walls and floors

How to use

Select a compatible rotary hammer with SDS-Plus chuck and secure the drill bit in the chuck according to the tool manufacturer’s instructions. Mark the drilling position on the work surface, ensure stable support and, where appropriate, use clamps or supports to prevent movement. Begin drilling at low speed to create a guide, then apply steady pressure with hammer mode engaged. Withdraw the bit periodically to clear debris and prevent overheating. For deeper holes, clear dust from the hole using compressed air or a brush before installing anchors or fasteners.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, ear protection and gloves. Match drill speed and hammer impact settings to the material being drilled; avoid excessive side load to prolong bit life. Inspect the bit for wear or damage before use and replace if the carbide tip is chipped or the flutes are deformed.
