Multi-Purpose Drill Bits: One Bit for Tile, Metal and Masonry
Open any contractor’s drill case and you’ll probably find a mess of bits: high-speed steel for metal, a masonry bit for brick, and a special glass and tile bit for the backsplash job. Each one does one thing, and when you grab the wrong one, it doesn’t do anything.
There’s a better way. Multi-purpose drill bits from Bad Dog Tools let you pull one bit out of the box and drill tile, masonry and metal with the same bit. In this post, you’ll learn why ordinary bits only handle one material, what makes the Bad Dog tip different, and how to get the most out of it.
Why You End Up With a Drawer Full of Different Bits
Walk into any hardware store and the drill bit aisle is sorted by material. That’s no accident. Most bits are built for one job:
- High-speed steel (HSS) bits for metal and wood
- Masonry bits for brick, block and concrete
- Glass and tile bits for ceramic and porcelain
So you buy all three, and then you buy them again when they wear out, get lost or snap. You spend more money, carry more gear and swap bits more often in the middle of a job.
Can a Masonry Bit Drill Metal? Why Look-Alike Bits Fail
A lot of people see a Bad Dog bit and assume it’s a masonry bit. We get it. Put a Bad Dog bit next to a good hardware store masonry bit and they look similar.
But looks are where the similarity ends. A masonry bit is made to drill masonry, and that’s it. Try it on metal or tile and it has no edge to work with. It won’t drill those materials.
That’s why the one-bit-per-material system exists. If a masonry bit could do it all, nobody would need the other two.
The Difference Is the Tip: Carbide, Titanium and Cobalt
What sets a Bad Dog bit apart is the tip. Every Bad Dog multi-purpose bit uses our Carboloid tip, a combination of carbide, titanium and cobalt, high-temperature brazed to an armored steel shank.
Regular bits don’t use that combination. A typical masonry bit may have a carbide insert, but not the same carbide, titanium and cobalt blend, and not built the same way. A standard HSS bit has no carbide at all. That tip combination is what lets one Bad Dog bit handle tile, masonry and metal instead of just one of them.
Multi-Purpose Drill Bits: One Bit for Tile, Metal and Masonry
With a Bad Dog bit, the process is simple:
- Pull the bit out of the box.
- Drill the tile.
- Drill the masonry.
- Drill the metal.
It’s the same bit every time, with no swapping and no trips back to the truck for the “right” one.
Quick Reference: One Bit Replaces Three
| Instead of buying… | For… | Bad Dog |
|---|---|---|
| High-speed steel bit | Metal | ✓ Same bit |
| Masonry bit | Brick, block, masonry | ✓ Same bit |
| Glass and tile bit | Tile | ✓ Same bit |
Getting the Best Results: Speed Matters
Bad Dog bits have a less aggressive cutting angle than a standard twist bit. Instead of biting into the material, they file through it. That means they need higher RPM to reach an effective tip speed at the cutting surface. If you run them too slowly, they won’t cut the way they’re built to.
Built in Bristol, Rhode Island, and Guaranteed for Life
Bad Dog Tools has been making drill bits in Bristol, Rhode Island, since 1988, with more than 6 million produced. We’re family-owned across three generations, and every bit is backed by our lifetime guarantee: we’ll repair or replace it, and you only pay return shipping and handling.
When a company guarantees a drill bit for life, it’s because they’ve watched it take abuse for decades.
Frequently Asked Questions
Are Bad Dog bits masonry bits?
No. They look similar to a masonry bit, but they're built differently. A masonry bit is made only for masonry. A Bad Dog multi-purpose bit uses a carbide, titanium and cobalt tip that drills tile, masonry and metal with the same bit.
Can a masonry bit drill metal?
Not well. A standard masonry bit is designed for brick, block and concrete, and it doesn't have an edge that works on metal or tile. That's why most people end up buying a separate HSS bit and a tile bit.
What is a carbide, titanium and cobalt drill bit?
It's a bit whose tip combines all three materials instead of relying on one. Bad Dog's Carboloid tip blends carbide, titanium and cobalt and is high-temperature brazed to an armored steel shank, so one bit can handle multiple materials.
What speed should I run a Bad Dog bit at?
Run it at a higher speed than you would a standard bit. Bad Dog bits have a less aggressive cutting angle and file through material rather than biting into it, so they need higher RPM for effective tip speed.
What does the Bad Dog lifetime guarantee cover?
Bad Dog will repair or replace your bit for life. You only pay the return shipping and handling.
