Spade Bit

Spade Bit

Spade bits are used to bore holes through wood quickly. As these bits leave a rough hole, they are often used to drill in areas that will later be covered or are not generally visible. Also known as paddle bits, they feature a wide, flat blade with sharp cutting edges that create fast, clean holes in wood or other soft materials. Each spade bit is made for drilling larger holes and is commonly used by trades like electricians and plumbers for boring through wall studs to run wiring or pipes. You'll find a wide range of spade bit blade sizes available in our store. 

Common Uses for Spade Bits 

Spade bits are reliable workhorses in both jobsite and home settings: 

• Woodworking Projects: Drill holes for dowels, hardware, or wiring through studs. 
• Plumbing and Electrical Applications: Bore holes in wood framing to route conduit or pipe. 
• DIY Home Improvements: Create pass-throughs for cords, mount shelves, or modify furniture. 

What to Consider When Buying a Spade Bit 

To get the right bit for the job, here are a few key features to keep in mind: 

• Size: Spade bits come in a range of diameters, usually from 1/4" to 1-1/2". Choose based on the hole size you need. 
• Length: Most bits are 6" long, but extended lengths (12" or 16") are available for deeper holes. 
• Shank Design: Look for a 1/4" hex shank if you're using a quick-change chuck or impact driver. 
• Material and Coating: High-carbon steel is common, while coated bits may reduce wear and friction during use. 

Spade Bit Options 

• Standard Spade Bits: Basic flat-blade design made for general-purpose drilling in wood. 
• Self-Feeding Spade Bits: Include a threaded tip that pulls the bit through the material, requiring less pressure. 
• Spade Bits with Spur and Reamer Tips: Score the wood before cutting for a cleaner hole and reduced splintering. 

Tips for Use

To get the best results and extend the life of your spade bits, keep these practical tips in mind during use: 

• Drilling Technique: To avoid splintering on the exit side, use a sacrificial board behind your workpiece or slow down as the bit exits. 
• Speed Control: Use moderate drill speeds—too fast and the bit may overheat or produce rough holes. 
• Pressure Application: Apply steady, even pressure. Let the cutting edges do the work without forcing the bit. 

Cleaning, Maintenance & Safety 

• Cleaning: Remove wood chips and wipe down bits after each use to prevent buildup. 
• Sharpening: Keep cutting edges sharp with a hand file to maintain performance. 
• Storage: Keep bits dry and stored in a case or holder to protect the edges and prevent rust. 
• Safety Precautions: Wear safety glasses and hearing protection. Make sure the drill is off before changing bits and secure the workpiece during drilling.
