Drill Bits: Good Through Bolts Friends

When you are installing through bolts upon your wall, your success on the task can be greatly affected by the type of drill bit you are using.  After all, the drill bit is the one that you would be attaching to your power drill, and your power drill is the tool that you use in making holes on your wall for your through bolts.  As thus, it is important for you to understand what kind of drill bits there are and what do you think is useful for whatever purpose you may have.

Here is a list of the most commonly used drills for installing fixings.

1. Twist bits.  Twist bits, also called twist drills, are the most common of the drill bits used.  They can penetrate a wide variety of materials, including wood, metal and plastics.  What distinguishes them from other drill bits are the spirals along their length as well as its front edges.  Twist bits are known to be quite brittle, and thus, extra care is necessary in handling them.

1. Masonry bits.  Just like what its name tells you, masonry bits are attached to power drills in order to create holes in concrete, tiles, blocks or bricks.  Just like twist bits, they also have spirals along the shaft.  What makes masonry bits special is that it has a special cutting tip typically made of tungsten carbide.  Masonry bits may look cool, but they are known to break and shatter under too much pressure.

1. Spur point bits.  Spur point bits look a bit similar to twist bits except for one thing – they have two raised spurs and a central point, which make for a straight hole in drilling.  Also called dowel bits, spur point bits are ideal for doing fast work with wood.

1. Bullet pilot point.  If you want a clean and accurately drilled hole, which is essential when installing fixings, you would want a bullet pilot point drill bit.  It looks almost like a spur point bit, except that they have grounded flutes.  They can also be used on metal surfaces and on plastics.

1. Tile bits.  Tile bits are used for drilling holes in ceramic tiles as well as in glass.  Just like the masonry bit, it also has a cutting tip that is crafted from tungsten carbide.  But unlike most drill bits used for installing through bolts, tile bits have straight shafts and do not have any edged spirals.

Drill bits are friends for through bolts because without the right drill bits, you would not be able to create a straight and accurate hole for installing your plugs.  It is very important that the hole you drill on whatever surface you are working for is just the right length and width so that the installation would be steady and strong.  If you are mounting something upon a wall with through bolts, the right drill bits will allow you to create a right-sized hole that will not cause cracks on the wall due to the weight of the mounted object.

How can I tell the size of a drill bit?

The drill bits are loose and the marking on them is faded away. Any ideas?

bits sizes are measured as their diameter, no? If this is indeed the case, drill a hole and measure it. Otherwise, no idea.
