Last week I helped you to pick the affordable drill press, and this week I have reviewed the Drill doctor drill bit sharpeners. Today I am analyzing the best drill bits for glass. I am also examining best diamond drill bits used in cutting the glass works.
The novice question is how do we get a hole in any glass material? The simple answer is you can drill the glass like you drill the wall, wood, and metal.
Glass drilling claims talent and experience. Using wrong tools and accessories, you will be losing time, energy, drill bits often, and the material as well.
There are specific drills bits for glass materials. It includes the spear head and diamond tip drill bits. With its super power glass cutting becomes an easier task. Anyways, make sure you having the necessary accessories that you need while drilling 2022 It’s like cardboard, plywood scrap, oil, and putty. Avoid last minute shopping.
You can use the drill machine and use the glass-cutting drill bits on that drilling machine. These glass drilling bits are made to drill the glasses, and the tiles kind of fragile materials. You can use the cordless hammer drills, corded hammer drills, drill presses and any other drill machines but the only thing to keep in mind is that you must use the drill-bits which are specially made to cut/drill the glass items.
Best Drill Bits for Glass
I do have the experience of using any drill bits – wood, metal, glass, tiles, ceramics, porcelain, jewelry and many more. But I am not going to pull them all here. I will only bring the best of best drill bits for Glass material here for you. I choose 8 best drill bits for Glass and review each one’s feature, pros, and cons.
Types of Drill bits for Glass
Based on the design, there are two types of drill bits. Both of these drill bits can cut the glass, tile glass, tiles, granites, marbles and slates. Though these are versatile drill bits, we will only focus on their glass drilling abilities. Choose the appropriate one based on what kind of glass you would drill.
- Spear Head drill bits
- Diamond coated drill bits
Best Spear Head Drill Bits for Glass
Spearhead drill bits named after their spear design. Spearhead drill bits are not perfect for large projects as the precision is little low compared to the diamond coated drilling bits. Spearhead drill bits are manufactured mostly using the tungsten carbide material.
These drill bits are less used than diamond coated drill bits. When you use the spearhead drill bits, you must use water around the cutting area or some other lubricant. This lubricant/water helps to cool off the excessive heat produced while drilling the glass material. Without the lubricant, the extreme heat can shatter your drill bit suddenly, and the glass may be damaged.
Though there are so many brands’ spearhead drill bits available in the market, the following two or the best drill bits for glass.
Best Diamond Drill Bits for Glass
Diamond drill bits are the popular glass cutting drill bits. These diamond drill bits are used to drill door/window glasses, mirrors, glass tiles, and aquarium.
These diamond drill bits are diamond tipped or diamond coated in the tip of the bits. When you employ these diamond drill bits in the glass, it can drill until the diamond tip/coat vanishes. Once the diamond tipped bits become dull (means diamond coat vanishes), we can’t use them further for glass-drilling operations.
You can’t use the drill bit sharpener to sharpen the diamond drill bits. You can’t use the diamond drill bits forever as you do with other wood & metal drilling bits. Once the diamond spray gone from the drill bit tips, there is no use for the bit on the glass drilling projects. Unfortunately there are no glass-cutting drill bits which we can sharpen and reuse.
I have 4 recommendations for you. All these four diamond drill bits are used by hundreds of people and have best reviews & ratings. Now you will see my experiences with the four drill bits.
Best Drill Bits for Sea Glass
Sea glass is nothing but the throw-away glass materials inside the sea and naturally-processed with the long duration (for many years), they become softened materials, and the edges are smoother to touch. Usually, 30 to 50-year-old sea glass items are finer and glitter. Beach glasses are also similar to the sea glass, but with less salty water in & around beaches, they don’t shine as much as sea glass does.
We get sea glasses in smaller sizes due to the erosion of salt water. To drill such little materials, we need sharper and tiny drill bits. I have picked the two best drill bits for sea glass for you.
How to drill the glass?
The glass is fragile. No doubt on that. But that truth shouldn’t stop you drilling with confidence. Your peculiar task is to choose the right drill bit for the cause – glass cutting drill bits. After selecting the best drill bit for glass drilling, you can typically drill as you would always. You can concentrate three things while the drilling operation ON.
#1. Drill Speed
What is the optimum speed to drill glass not to break it? There is nothing like standard speed for drilling glass. But it is recommended start drilling the glass with the lowest possible speed and keep on increasing the speed to the needed level later.
Use the best drill press (in case you drill the glass with a drill press, you can drill the glass with other hand drills, cordless drills too) which has options to set up different speeds. I have listed here the 5-Speed drill press machines priced under $200. Use the quality drill bits for glass along with these drill press machines at the low speed first. Once the drill bits started penetrating the glass, increase the speed slowly and finish the job correctly.
#2. Drill Pressure
The hand pressure you give on the glass while drilling is essential. It is essential to provide enough pressure to the drills so that the diamonds drill bits not slipping away from the target. That doesn’t mean you should give high pressure anyway. High pressure only will add up the heat in diamond drill bits; the added heat will affect your drill bits and in some cases the glasses too.
You should give the pressure firmly at first in a way not to slip the drill. Once the drill bits started drilling a hole increase the pressure very gently. Never put so much pressure on the glass. This work comes from the practice and experience. If you are drilling the glass first time, then try first drilling the waste glass materials initially.
Do not forget it. Else your glass item is going to crack for sure. Use water or special lubricants in the drill bits and in near the target area on the glass. Use more lubricant if you feel the glass is harder to drill. While the drill operation goes on, stop for a minute, add some lubricant and continue drilling the glass. This gap reduces the heat on the diamond drill bits and avoids breaking the glass.
Always keep the drill bits wet. A dry drill bit spoils the whole process. Keep in mind that. You can buy special lubricants from Amazon which to use it for the drill operations.
Last but least, safety is first. Wear gloves in your hand, keep on using water or coolant near drill bit tips, and give low pressure on your hand drill. Once you feel the drill bit is dull, change to the new drill bit. Do not use the dull bit at any cost. The dull bit can break your glass material.
What kind of glasses can we drill?
Want a mirror attached to the wall in your living room? You can drill four corners and attach the fastener to the wall. Yes, you can drill mirror glass.
You have a lot of wine bottles and your wife want to use them to decorate your balcony. You can use the glass-drilling bits to make a hole and go on creative with the holes. Yes, you can drill your wine bottles.
Want to give a try for the glass tiles that extend the beauty of your home? You can drill the glass tiles and decorate the house.
Want to install an aquarium like a setup to beautify your living hall? You can construct it using the glasses on which you can drill holes and fix it to the wall.
So this means that you can drill almost any type of glasses. There are some exceptions as the tempered glass and safety glass.
Factors to choose the best drill bits for Glass
Diamond coated drill bits are what we use to drill glass, ceramics and often tiles. Unfortunately, the life term of diamond coated drills bits is limited. We can’t sharpen these diamond drill bits and keep on using them repeatedly forever as we do in other drill bits. Once the diamond coating went away, we need to go for new ones. Hence the durability is what we need to look first. Some special diamond drill bits only lasts for five drill operations in jewelry/glass cutting. So knowing the life term of a glass cutting drill bits in upfront helps us to expect a real-life term.
#2. Manufacturing material
I have already mentioned that we use commonly two types of manufacturing material. The one is Diamond sprayed/coated drill bits and the second one is tungsten carbide tipped drill bits.
These are harder materials than glass. That is why these drill bits are best in drilling the glass items. These types of drill bits help us to drill not only the glass but also the sea glass, ceramics, tiles and other harder materials.
#3. Types of drill bits
There are numerous types of drill bits available. They all are not drilling the glass. I will pick for you only the types of drill bits used to drill the glass. Spearhead drill bits and diamond drill bits are the two glass drilling bits. I will explain them just after sometime. Go with your choice. I recommend using diamond drill bits for glasses. Spearheads are Ok too, but they work fine in tiles and ceramics better. For glass drilling, Diamond drill bits are safer and precise drilling.
Usually, the diamond drill bits and carbide coated spearhead drill bits are sellable in sets of around $10 per set. Spearheads are more durable, and they are worth the money. Diamond drill bits are for perfect finishing but less durable than spearhead so often you will have to buy new ones. I can’t give the durability of each drill press available in the Amazon because they are so much in the count.
If you have never drilled the glass before, then first give a few trials on waste wine bottles. Do not straight away drill the precious glass materials. You will need to learn first at what angle you must start drilling initially, having slow drill speed, giving moderate pressure, and remembering the coolant or water usage. There are video tutorials on the web and YouTube for your comfort. See the instructions provided in these tutorials. Equip yourself for the perfect cut-outs in the glass.
The above mentioned eight best drill bits for glass are easy to handle as the bits fit almost in all types of hand drills and drill press machines. There are no compatibility issues.
Spearhead glass-cutting drill bits are good enough to drill glasses. But the perfect finish you would expect comes with the diamond drill bit types. The hole saw model drill bits are great glass-cutters and in layman terms, they are ideal for glass hole extractors or removers. You can go with the hole saw diamond drill bits confidently on any glass items.
Sea glass and beach glass drilling works need special care because these are valuable materials. You can go with the best drill bits I mentioned for Sea glass or jewelry stones. Almost all the above-mentioned glass drill bits are Ok for drilling tiles, granites and marbles. So, these are versatile drill bits you can use for any work.
I hope I have guided to choose the best drill bits for glass work. Let me know which one bit you liked and how it performed on your glass item. Share your glass drilling experience with us.
