Drill bit DeWALT DT8924-QZ 8 mm diameter 210 mm length

The DeWALT DT8924-QZ 8 mm diameter, 210 mm length drill bit is designed for use with rotary hammers and SDS Plus chucks. It has a solid carbide tip with four cutting faces and a four-flute helix that helps remove debris efficiently, reducing vibration and resisting jamming when encountering rebar. The bit weighs approximately 40 g and is intended for drilling in concrete and other masonry materials.

Advantages

The solid piece carbide tip with four cutting faces improves cutting stability and extends tip life. The four-flute helix maximises debris evacuation for faster, cleaner drilling. The design reduces vibration and lowers the risk of the bit locking when striking rebar, providing consistent drilling performance in hard concrete.

Suitable for

• Drilling holes in concrete and masonry
• Use with rotary hammer drills having SDS Plus chuck
• Installing anchors, dowels, and fixings in structural concrete

How to use

Insert the DT8924-QZ bit into the SDS Plus chuck of a compatible rotary hammer and secure it according to the drill manufacturer's instructions. Use the rotary hammer in hammer or hammer-drill mode as appropriate for concrete. Apply steady pressure without forcing the bit; allow the tool and carbide tip to cut the material. Withdraw periodically to clear debris if drilling deep holes.

Usage recommendations

For best results, use the correct drill speed and hammer setting for the material, wear appropriate eye, ear and hand protection, and select an appropriate drill length and diameter for anchors and fixings. Avoid excessive side load on the bit to prevent premature wear.
