G'day! You're in the middle of a weekend reno. You need to hang a heavy-duty shelf, install a TV bracket, or run some pipework, and you're faced with a good, solid, Aussie brick wall. You grab your standard drill bit (the black or silver HSS one you use for timber), give it a burl, and... screeeeeech.

You're met with a cloud of smoke, a deafening noise, a knackered drill bit, and a wall that's barely got a scratch. It's a fair dinkum frustrating moment.

That, mate, is because you've brought the wrong tool to the fight. For brick, concrete, stone, or mortar, you need a special kind of beast: the masonry drill bit.

How to Spot One: The Tip is the Giveaway

A masonry drill bit looks different from your standard timber or metal bit. The biggest giveaway is the tip. Instead of being twisted to a sharp point, a masonry bit has a chunky, arrow-shaped head made of tungsten carbide.

This tip is incredibly hard. It's not designed to cut the material like a wood bit. It's designed to pulverise it.

The Golden Rule: You MUST Use the Hammer Function

This is the most important part, mate. A masonry drill bit is pretty useless on its own. It's designed to work as part of a team with a drill that has a hammer function.

When you switch your drill to the 'hammer' setting (it usually has a little hammer symbol on it), the drill doesn't just spin; it also smashes the drill bit forward hundreds of times a second. It's this high-speed jackhammering action that allows the carbide tip to chip, pulverise, and blast its way through the hard material.

Trying to use a masonry drill bit without the hammer function is like trying to chop down a gum tree with a butter knife – you'll be there all bloody day and get nowhere. (And never use the hammer function on timber, metal, or tiles!)

When to Use This Ripper Bit

A masonry drill bit is your go-to for drilling into any hard building materials:

• Brick walls (both solid and cavity)
• Concrete (slabs, foundations, block walls)
• Mortar joints
• Stone and tiles (though for delicate tiles, a diamond-tipped bit is often a safer bet to prevent cracking)

It's the essential tool for any job that involves fixing something to a solid wall, like installing shelving, clotheslines, brackets, or running pipes and conduits.

Installation: A Hole is Just the Start

Knowing how to drill the hole is a ripper skill for any Aussie DIYer. But what you're putting in that hole is a whole different ball game.

If you're drilling a hole to run a 240V electrical cable for a new light or power point, your DIY job stops the second the hole is drilled. In Australia, it is illegal and extremely dangerous for anyone other than a licensed electrician to do any fixed wiring.

A qualified professional will not only drill that hole safely, but they'll also have the right, compliant gear to run through it. A pro installer won't just grab their gear from the retail shelf; they get their supplies from a proper electrical wholesaler to ensure everything is trade-quality and meets Australian standards.

As one of Australia's most comprehensive electrical wholesaler and supplier networks, Schnap Electric Products stocks the lot for the professional installer. They've got all the heavy-duty gear that gets installed in or on those masonry walls, including the rigid, weatherproof conduits, the heavy-duty power points, junction boxes, and all the compliant cabling that a licensed professional needs to do the job right. For a job that's safe from start to finish, the pros use the right tools and the right components from a supplier like Schnap Electric.
