The Essential Guide to Drill Bits for Metal Cutting

When you’re working with metal, you know the importance of having the right tools. A good drill bit can be the difference between a smooth, clean hole and a frustrating mess. Whether you’re a seasoned pro or a weekend warrior, the right drill bit is essential. In this guide, I’ll walk you through what makes a great metal-cutting drill bit and introduce you to a standout option: the ToolAnt M35 Step Drill Bit.

What Makes a Drill Bit Perfect for Metal

Not all drill bits are created equal, especially when it comes to cutting through metal. Here’s what you should be looking for:

1. Material Matters: High-Speed Steel (HSS) is a go-to for metal, but when you add cobalt (like in M35 bits), you get extra toughness and heat resistance—perfect for tougher metals.
2. Coatings Count: A coating like titanium or black oxide helps the bit last longer by reducing friction and wear.
3. Tip Design: A split-point tip is key. It starts cutting right where you place it, reducing the chance of the bit wandering across the surface.
4. Step Design: Step drill bits are brilliant if you need different hole sizes. No need to swap bits mid-project—just keep drilling.

Meet the toolAnt M35 Step Drill Bit

Now, let me introduce you to the toolant M35 Step Drill Bit. Here’s why it’s a game-changer:

• Built Tough with M35 Cobalt Steel: This bit is made from M35 steel, which includes 5% cobalt. That means it’s ready to handle tough metals like stainless steel and iron without breaking a sweat.
• Versatile and Efficient: The step design lets you drill holes from 3/16″ to 7/8″ without needing to switch bits. This makes your job faster and your work cleaner.
• Precision You Can Trust: The split-point tip ensures that your drill starts exactly where you want it to, reducing mistakes and wasted materials.

Pro Tips for Drilling Metal

Keep It Cool: Use a cutting fluid to keep things cool and prevent your bit from wearing out too soon.

Slow and Steady: Don’t rush it—use a slower speed to avoid overheating the bit.

Steady Pressure: Apply firm but steady pressure. Too much force can damage the bit; too little won’t get the job done.

Pilot Holes Help: For larger holes, start with a small pilot hole to guide the drill bit and keep it on track.
