Drill bit DeWalt DT4587 self-drilling socket drill 74 mm

DeWalt DT4587 self-drilling socket drill 74 mm is a combination drill and fastening bit designed to drill through thin metal and create a hole ready for a screw or fastener in a single operation. The 74 mm overall length provides reach for common construction and metalworking tasks while the socket-style mounting fits drills and drivers that accept hex or socket bits. This socket drill is intended to speed installation where pre-drilling and separate tapping are impractical.

Advantages

The DeWalt DT4587 integrates drilling and fastener seating in one tool, reducing the number of operations on-site and cutting assembly time. Its 74 mm length offers better access in confined or deep-reach areas compared with shorter bits. The socket-style configuration ensures secure engagement with compatible power tools and improves torque transfer for consistent results. Manufactured by a brand known for tool durability, the bit is suitable for repetitive use in light- to medium-duty metal fastening tasks.

Suitable for

• Installing self-drilling screws in thin sheet metal and light-gauge steel
• Fastening metal roofing, cladding and framing components
• Construction and assembly tasks where a combined drill-and-fastener action speeds work
• Use with drills and impact drivers that accept socket-style bits

Key specifications

• Overall length: 74 mm
• Tool type: self-drilling socket drill (combined drill and fastener bit)
• Mounting style: socket-style bit for compatible drills and drivers
• Typical applications: drilling and preparing fastener-ready holes in thin metal
• Suitable materials: light-gauge steel, sheet metal, metal roofing panels

How to use

Install the DeWalt DT4587 into a compatible drill or driver, ensuring the socket-style connection is fully engaged. Position the bit on the workpiece at the desired fastening point and apply steady pressure while running the tool at a moderate to high speed depending on material thickness. The bit will drill the hole and form a fastener-ready opening; stop the tool once the bit has passed through the material and the screw or fastener can be driven. Maintain a straight drilling angle for accurate hole placement and consistent results.

Usage recommendations

Use appropriate personal protective equipment (safety glasses and gloves) and select a drill or driver with sufficient power and torque for metal fastening. For thicker or hardened materials, consider pre-drilling with a conventional drill bit and confirm compatibility of fasteners with self-drilling hole dimensions. Inspect the bit for wear before use and replace when cutting performance declines.
