What degree drill bit is best for metal?
The two most common point angles for metals are 118 degrees and 135 degrees. The sharper 118-degree angle is best used for softer metals. Harder metals will wear the bit faster. The 135-degree self-centering point angle is flatter, putting more of the bit in contact with the substrate.
What is the advantage of a spade drill?
Spade drills offer some distinct advantages over twist drills. Runs at higher speeds and feed rates without tool breakage. Drills in one-pass. A chip curl is ground along the cutting edges to break the chips as they form.
Are spade bits good?
Spade bits are a popular choice for drilling large diameter holes (1/2″ or more). They can drill holes much faster than other wood drill bits. Spade drill bits are ideal for home improvement and DIY jobs.

What is a spade drill bit?
These bits are awesome for drilling holes in metal. They’re designed to handle tough materials like steel, aluminum, and cast iron. You’ll find them in various sizes and styles to tackle a range of projects.
Why Use Spade Drill Bits?
So, why choose spade drill bits? They have some cool advantages:
Faster drilling: You’ll zip through metal faster than with other bit types.
Clean holes: They create cleaner holes with less burring, which is super helpful if you’re working with precision.
Durable: They’re made from high-quality materials to handle tough applications.
Versatile: Spade bits can handle a wide range of materials and thicknesses.
Spade Drill Bit Anatomy
Let’s break down the anatomy of a spade drill bit:
The Spade: This flat, wide section is what cuts the hole. It has two sharp edges that create the hole.
The Shank: This connects the spade to the drill chuck. It’s usually cylindrical and fits standard drill chucks.
The Center Point: A small point in the center of the spade helps guide the bit and prevent it from wandering.
The Pilot Point: This small point is located ahead of the spade. It acts as a guide for the spade, ensuring a clean and accurate hole.
Choosing the Right Spade Drill Bit
Picking the right spade drill bit depends on a few things:
Material: You’ll need a bit designed for the specific metal you’re working with.
Hole Size: Make sure you choose a bit with the right diameter for the hole you want to drill.
Depth: Consider how deep you need to drill. You might need a bit with a longer shank if you’re drilling deep holes.
Using Spade Drill Bits
Now, let’s talk about how to use these bad boys:
1. Secure Your Workpiece: Make sure your metal is held firmly in place so it doesn’t move while drilling.
2. Select the Right Speed: Choose a speed that’s appropriate for the metal and the size of the hole you’re drilling.
3. Apply Light Pressure: Don’t press too hard. Let the bit do the work.
4. Keep It Cool: Use cutting fluid or lubricant to keep the bit cool and prevent overheating.
5. Avoid Overheating: If the bit starts getting hot, give it a break to cool down.
Common Types of Spade Drill Bits
Here are some popular spade drill bit types:
High-Speed Steel (HSS): These are the most common type of spade drill bit. They’re durable and affordable, making them a great choice for most applications.
Cobalt Steel: These bits are even tougher than HSS and can handle higher temperatures. They’re ideal for drilling difficult materials like stainless steel.
Titanium Nitride (TiN) Coated: These bits have a coating that helps them resist wear and tear, extending their lifespan.
Brazed Carbide: These bits are the top dogs for heavy-duty applications. They can drill through tough materials like hardened steel.
FAQs about Spade Drill Bits
Q: Can I use a spade drill bit on wood?
A: You can, but it’s not the best choice. You’ll get better results with a regular wood drill bit.
Q: How do I sharpen a spade drill bit?
A: You can sharpen them with a diamond hone or a grinding wheel, but it’s a bit tricky. You might be better off getting new bits.
Q: What are the differences between spade drill bits and twist drill bits?
A: Spade bits are designed specifically for drilling metal, while twist drill bits can handle a wider range of materials. Twist bits are better for general-purpose drilling, while spade drill bits are more suited for drilling metal.
Q: What is the best way to store spade drill bits?
A: Store them in a dry, dust-free place. You can also use a drill bit case to protect them from damage.
So there you have it! Spade drill bits are a powerful tool for any metalworker. Now you know how to choose, use, and care for them. Happy drilling!
