The DeWalt DT8919 drill bit for rotary hammer is a 6.5 mm diameter, 310 mm overall length drilling tool supplied as a single piece. It is designed for use with compatible rotary hammers to create medium-diameter holes in masonry and concrete. The solid, elongated shank provides reach for deeper fixings or installations while the carbide tip and flute geometry are intended to assist controlled dust removal and efficient drilling in dense substrates.

Advantages

This drill bit offers a balance of length and diameter that suits common installation tasks without excess bulk. Its construction is aimed at delivering consistent drilling performance in masonry and concrete; the length provides extra reach for recessed or deeper anchor points. Supplied as one piece, it is ready for immediate use with a compatible rotary hammer and is suitable for repetitive drilling where medium-sized holes are required.

How to use

Install the drill bit into a rotary hammer that supports the matching shank type and secure it according to the tool manufacturer’s instructions. Mark the drilling position and start at low speed to position the bit, then apply steady pressure and allow the hammer action to do the work. Use appropriate drill speed and impact settings for masonry or concrete, periodically withdraw the bit to clear dust from the hole and avoid overheating. Always ensure the bit is suited to the anchor or fixing diameter before enlarging holes.

Usage recommendations

Use personal protective equipment including safety glasses, hearing protection and dust mask. For prolonged drilling, clear debris regularly and allow the bit to cool to extend service life. Match drill diameter and depth to the fixing specifications and use a compatible rotary hammer with proper impact energy for consistent results.
