Spade drill bit DeWalt DT4814 — single-piece wood drilling bit

The DeWalt DT4814 spade drill bit is a single-piece flat paddle-style bit engineered for drilling wood and other soft materials. Constructed from chrome vanadium steel, it features a ground central point and cutting edges for accurate location and clean cutting. The bit is designed to transfer drilling power efficiently, produce fast bores and enable effective chip removal, making it suitable for through-holes, rough woodworking and quick pilot or clearance holes with hand drills and drill drivers.

Advantages

This spade drill bit is made from high-quality chrome vanadium for durability and reliable performance during repetitive wood drilling tasks. The ground chip breaker reduces splintering at the exit and helps produce relatively clean holes while improving drilling efficiency. Precisely ground central point and cutting edges aid in accurate positioning and consistent cutting action, reducing walking and the need for rework.

Suitable for (tasks / use cases)

• Drilling through-holes in softwood and construction lumber
• Creating clearance and pilot holes for screws and bolts
• Rough carpentry and framing work
• Quick hole preparation in DIY and renovation projects

Key specifications

• Material: chrome vanadium steel
• Design: single-piece spade / flat paddle
• Cutting features: ground central point and ground cutting edges for accurate location
• Chip control: ground chip breaker to reduce splintering and aid chip removal
• Compatibility: suitable for use with hand drills and drill drivers
• Application: optimized for wood and other soft materials

How to use

Secure the spade bit in the drill chuck and ensure it is tightened correctly before starting. Mark the drilling position and, if needed, use a pilot punch or centre mark to prevent walking. Begin drilling at a moderate speed to allow the ground central point to locate the hole, then increase speed as appropriate for the material and hole size. Apply steady pressure; allow the bit to remove chips naturally and withdraw periodically on deeper holes to clear debris and avoid clogging. Finish the hole by reducing speed as the bit exits to minimize splintering.

Usage recommendations

For best results, use the bit with a drill that provides consistent torque and maintain proper speed for the material thickness. Clamp workpieces securely and wear appropriate personal protective equipment, including eye protection and hearing protection. Inspect the bit for wear or damage before use and replace if cutting edges are dull or the shank is bent.
