Spade drill bit STANLEY 5287978 (3.8 cm) – 1 pc

STANLEY 5287978 is a single spade drill bit with a 3.8 cm cutting diameter designed for use with standard electric drills. The flat paddle-shaped tip clears wood quickly and is intended for through-holes and rough boring in timber and similar soft materials. Supplied as one piece, this spade drill bit is aimed at general-purpose holemaking tasks where fast material removal is required.

Advantages

The paddle-shaped cutting tip enables aggressive wood removal for faster drilling compared with twist bits of similar diameter. A simple, robust one-piece design offers straightforward installation and removal in a drill chuck. The wide 3.8 cm diameter produces large, clean through-holes for applications such as running cables, creating access points or installing fasteners in softwoods and composite panels.

Suitable for

• Drilling through timber for carpentry and framing
• Creating cable and service entry holes in wooden structures
• Rough boring where fast material removal is prioritized over precision
• Work on softwood, plywood and composite board materials

Key specifications

• Type: Spade (paddle) drill bit
• Cutting diameter: 3.8 cm
• Material compatibility: Wood and similar soft materials
• Quantity: 1 piece

How to use

Fit the spade drill bit securely into the drill chuck and tighten according to the drill manufacturer’s instructions. Position the tip at the marked drilling point and run the drill at moderate speed, applying steady pressure. For through-holes, begin drilling at lower speed to establish the cut, then increase speed as needed for faster removal. Back the bit out periodically if long holes produce chips, and clear debris to maintain cutting efficiency. When drilling near edges or thin panels, support the workpiece to reduce splintering.

Usage recommendations

Use appropriate personal protective equipment such as eye protection and hearing protection. Select drill speed and feed pressure suitable for the wood type; reduce speed for hardwoods and increase chip clearing to avoid overheating. For cleaner exit holes, consider backing the workpiece with scrap wood or using a stepped approach.
