Drill bit DeWalt DT8951-QZ, 160 mm length, pack of 10

DeWalt DT8951-QZ drill bit, 160 mm length, supplied in a pack of 10. This set of replacement bits is intended for repetitive drilling tasks in masonry, stone and concrete where consistent length and a reliable cutting tip are required. Each bit features a solid-piece carbide tip and four cutting faces to help reduce the risk of jamming when encountering reinforcement and to maintain drilling progress in demanding substrates.

Advantages

The four-flute helix enhances debris evacuation for faster drilling and cleaner holes, while the brazed carbide tip-to-body joint provides a durable bond that resists breakage under load. Supplied as a pack of ten, the set ensures continuity of work on larger jobs or in workshops and reduces downtime caused by frequent bit changes. The geometry and solid carbide cutting faces are designed to provide consistent hole quality when used with compatible rotary hammer or impact drilling tools.

Suitable for

• Drilling plug and anchor holes in masonry
• Boring holes in all types of stone
• Concrete drilling for fixtures and fastenings
• Workshop and maintenance tasks requiring multiple identical bits

Key specifications

• Overall length: 160 mm
• Pack quantity: 10 pieces
• Tip material: solid-piece carbide with four cutting faces
• Flute design: four-flute helix for improved debris removal
• Tip-to-body connection: brazed joint for enhanced durability

How to use

Fit the drill bit into a compatible chuck or tool holder according to the power tool manufacturer's instructions and secure it firmly before starting. Use appropriate drilling speed and feed pressure for masonry and concrete; start at low speed to establish the hole, then increase speed as appropriate. Periodically withdraw the bit to clear debris and allow cooling. Replace worn or damaged bits—do not attempt to resharpen solid-piece carbide tips.

Usage recommendations

When drilling masonry and concrete, use a rotary hammer or hammer drill suitable for the chosen bit size and wear safety equipment including eye and hearing protection. Match drilling speed and pressure to the substrate to prolong bit life; keep the bit clean and allow intermittent cooling when performing long or continuous drilling sequences.
