Drill bit DeWalt DT4872-QZ — diameter 10 mm, length 615 mm, 1 piece

DeWalt DT4872-QZ drill bit, single piece, with a 10 mm diameter and 615 mm overall length, is designed for deep-hole drilling in wood and wood-based materials. This long frame drill bit offers stable penetration and precise guidance for tasks that require extended reach, such as door hinge installation, cabinet fitting, and through-holes in thick timber sections. The bit weighs approximately 247 g and is supplied as one replacement/spare bit compatible with drills that accept this shank type.

Advantages

The DeWalt DT4872-QZ combines a long profile with a 10 mm cutting diameter to enable deep, straight holes while maintaining control and accuracy. The threaded and glued connection between drilling and clamping parts ensures structural stability during use. A tapered transition between the drill and clamp facilitates easy extraction of the bit from the drilled hole. The bit is suitable for fast, accurate and clean drilling results in hardwood, softwood and laminate.

Suitable for

• Drilling long through-holes in solid timber and structural wood components
• Installing door hardware, hinges and long fasteners
• Cabinet and furniture assembly where deep reach is required
• Renovation and construction tasks needing extended-reach drilling

How to use

Mount the DeWalt DT4872-QZ securely in a compatible drill or frame drill according to the tool manufacturer’s instructions. Align the bit with the marked drilling point, start at low speed to establish the pilot path, then increase speed as appropriate for the material. Apply steady axial pressure without forcing the bit; allow the cutter to remove material and withdraw periodically to clear chips when drilling deep holes. After use, retract the bit using the tapered transition if it becomes tight in the hole.

Usage recommendations

Use appropriate personal protective equipment (eye and hearing protection, gloves) and clamp workpieces where possible. Match drilling speed to the wood type—lower speeds for hardwoods and moderate speeds for softwoods and laminates. Keep the bit clean and free of resin build-up to preserve cutting performance and inspect for wear before extended use.
