Whether you’re hanging up an electric power strip, mounting a speaker or putting a shelf on the wall there will be times when you need to match up holes to bolt things on. Luckily, there are plenty of quick and easy ways to make sure you get your drilling straight.
The classic way involves a little bit of measuring and eye work. First, you need to mark the position of one of the holes with a pen. Then you need to draw the cross line of the new hole on the mating piece with a center punch (which can be time consuming). Finally, you need to use that as a guide when drilling the matching holes. This method is great for small projects that you can take out to your workspace and it works reasonably well for hard materials like metal.
However, there are many situations where it can be difficult or impossible to do this. This is particularly true on site, away from static, precision milling and drilling machines. That’s why we created our VersaDrive construction and steel reamer range - the perfect solution for metalworkers and erectors to keep the job moving when they need to enlarge an existing hole in hard materials on site.
It is possible to align a drill using the centre punch/punch mark, but this can be risky. Small drill bits can wander off the centre mark and in the worst case snap. You can also use a combination square, but it can be tricky to position it correctly on a round piece of wood, metal or plastic.
