Overview of The Best Glass Drill Bits
Drill bits are used to make holes in a wide variety of materials. The materials you are going to drill into determines the kind of drill bits you should buy. Drill bits have different designs, they’re made of different materials, and you need to use different drilling techniques to drill some materials without chipping, cracking or shattering the material. Always use the right bit for the job!
Best Drill Bits for Glass – Buying Guide
There are lots of available options on the market, getting the best drill bits for glass seems a bit challenging. You should consider some important factors before make purchase.
The Material Used in the Drill Bit
Different materials are used to make different types of drill bits. Cobalt drill bits, for example, are meant to drill stainless steel, cast iron and aluminum. Tiles are made out of stone, glass, ceramic and porcelain, and these materials are very different from drilling wood.
You need special drill bits to drill into these surfaces, and unless you’re drilling a very small hole the bit should have a diamond tip—that is, it will be coated with diamond sand to cut cleanly.
Shape of the Bit
Drill bits are used to make holes in a surface or material. Counter skin drill bits, hole saw drill bits, and drill bits with a variety of angles on the heads are all used for different reasons, and in different materials.
The smallest glass bits are shaped like an ordinary bit, but medium to large size holes require a hole saw style bit. This style of bit stops the edges of the hole from chipping and cracking, and the hollow core of the drill bit safely removes the drilled materials from the hole.
How to Drill a Glass
If you are planning to drill into glass, there are certain steps you need to take. Depending on the thickness of the glass and the type of drill bit, the manufacturer may recommend that you begin drilling on an angle instead of straight down into the surface.
Also, the friction of drilling through hard, dense glass, ceramic, porcelain, stone and shells gets a drill bit hot—fast. It is important to keep the drill bit cool while you are drilling. To do this, make sure there is water around the area where you will drill the hole. You may need to make a little dam to hold the water in as you are drilling.
Drill slowly, and relax—you don’t want to break the glass or the bit by applying too much pressure. Take it nice and easy, use water to keep the bit cool, and let the bit do its job.
Hold Your Drill Firmly and Don’t Shake
Make sure you are drilling on a steady surface; you don’t want any shaking or vibration that could damage the hole you’re drilling or the surface you’re drilling into.
Always Clean Your Drill Bit After Use
As you drill glass, your drill bit is creating many tiny chips and a lot of dust. And even though you are using water, there will still be some heat in your drill bit. As soon as you finish drilling, rinse your bit under running water or let it cool down in a jar of water. Then take a paper towel or a rag and wipe off the bit. Make sure there is no dust or reside left on the bit. Store your bit in a case or container that will protect the edges of the bit so they don’t get chipped. Depending on what your bit is made of, you may even want to wipe your bit with a little light oil to protect it from corrosion.
Sharpen Your Buts Always
For your drill bit to function appropriately, it is important to sharpen it. It will not only make sharp holes but it will require less pressure when you are drilling, which will make it much more comfortable as you are working. Blunt drill bits are prone to breakage because you will need to push it harder to make holes on the glass. Buy a good bit sharpener to sharp your bits.
Also, make sure your bits keep their original angle. Different angles are used for drilling into different kinds of materials. And avoid dropping your drill bits; it dulls the bits, and in the case of diamond-coated hole saws, you don’t want the diamond dust getting knocked off the bit. With proper use and care, your bits should last a long time and do a great job of drilling the materials they are made to penetrate.
