How to drill bottom of flower pots?

Most of the decorative flower pots do not have the bottom drainage holes. They look nice but you do need the bottom hole.

For drilling the bottom drainage holes, you will need diamond coated hole saws.

Best diamond coated hole saw drill bits come with no center pilot drills. Pilot drill bits are for softer materials such as wood or plastic.

To make your initial mark, you can either start at an angle or you can make your own guide with a piece of scrap wood.

After you make your initial mark, you can even out the drill bit and go full vertical.

Cooling the drill bit is very important. How diamond hole saws will lose the diamond particule. You can use water or ice.

Attaching the Drilax Flexible Shaft to a Rotary Tool

drilax-flex-shaft-1

1- First, if is your rotary tool has a threaded collars on the motor end, you will need to remove it by turning ccw (counter clock wise). You will need the collar when you attach a tool directly to the rotary tool. You will not need it with the flex shaft.

2- Hold the flexible shaft by the silver color fitting end (you will be able to see the inner shaft core). And pull the inner core about 2 inches. If you need a pair of pliers to hold it, that’s normal.

drilax-flex-shaft-silver_end

MAKE SURE THE ROTARY TOOL IS UNPLUGGED FOR THE NEXT STEPS

3-Now, the idea is you are attaching the core of the flex shaft into the rotary tool collet just like you would attach any kind of tool with a 1/8″ shaft. The flex shaft is there to transfer the rotation, that’s it. It is just like an extension. Push the core of the flex shaft into the rotary tool collet and tighten the collet. You can use the collet lock button to prevent it from turning while you are tightening the nut.

4- You can now screw the silver color fitting end of the flex shaft onto the  rotary tool housing. This is where you removed the collar. We are not done attaching the flex shaft to the rotary tool. From now on, the next steps are about attaching the bit or burr to the flex shaft.

drilax-flex-shaft-blac-end

5- The other end (BLACK COLOR) of the flex shaft is where you will insert the desired attachment tool such as a diamond disc or a burr. You will be using the silver chrome L shaped piece for this stage. There is a hole on the side of the black side of the flex shaft. And there is another hole under the black side. When you align these two holes by turning the silver tip on the black end, insert the L shaped metal. This step may sound confusing but it’s simple. The inner metal part on the black end of the shaft will want to turn as you try to attach the tool. The L shaped metal is there to help you hold it while you try to twist the tip.

6- You can now attach the bit. And tighten the nut at the tip of the black end of the flex shaft.

Drilling Glass Blocks

Drilling in glass block or bottles is not different than drilling in traditional glass.  If you employ the acceptable speed, use low drill pressure and lots of water for lubrication, you will not have any issues.  Glass breakage with inorganic compound bits is fairly common, however with the right diamond drill bit, it’s very rare.  There are a couple of vital facts and tips which are useful for drilling glass blocks.

light_bottle

There are various differing types and designs of glass block created by many alternative makers.  Most have some style of style or pattern, however, for drilling functions, there are 2 main characteristics.  Glass blocks will vary considerably on the thickness of the glass wall and a few glass block is tempered.  This info is never disclosed on the block itself, however ought to be thought-about once shopping for glass block for crafting functions.

If the glass block is 3/8″ thick, it’ll take thrice as long to drill compared to a 1/8″ thick block.

Tempered glass ought to be avoided.


Making a mini dam around the hole is the most effective cooling method for drilling in glass blocks.

Glass block contains a vacuum within. a number of the water and glass dirt can forever be sucked within once the opening breaks through.  However, it’s simple to rinse out {the within|the within} of the block with water as long because the dirty water inside isn’t allowed to dry out.  The plug from the opening can generally be force into the block – it’ll typically drop out simply once the within is rinsed.  However, if an excessive amount of pressure was placed on the drill because the hole breaks through, it will cause the plug to possess a aptitude from the break on the rear of the opening.  Normally, you’ll be able to take away the plug with a combine of needle nose pliers, however the simplest answer is to scale back the drill pressure once nearing the rear of the glass to avoid break because the drill breaks through.

There is a great set of 5 diamond drill bits with the best selection of sizes on Amazon.  Previous customers were able to 10 to 30 holes in glass with 1 single bit.

The Speed of the Drill

For smaller sized holes, such as 1/2″ or smaller, the maximum suggested speed is 600 RPM.

Larger holes will need slower drilling speeds, for example:

400 RPM for 1 inch Holes
200 RPM for 2 inch Holes
125 RPM for 3 inch Holes

The idea is, as the speed increases, there is more and more friction on the rim of the drill bits and the coolant can not stay on the surface.

Keeping the drill bit on target

Most of the diamond coated drill bits – hole saws are manufactured without a pilot drill bit.  People who are used the pilot drill bits from wood – plastic hole saws, may think of this as a missing component but it is actually done on purpose. Because pilot drill bits will crack glass – tile – granite, etc.

 

We specifically do not have the pilots because a) pilots get dull before the hole saw b) pilots have a tendency to crack some materials like glass

To help starting the hole, we have a guide.

https://www.amazon.com/DrilaxTM-Porcelain-Included-Removable-Bearings/dp/B00V3UONCW

 

You have to have a way to keep the drill bit on target. Here are some methods:

a- You can make your own guide out of plywood – plastic or even a card board. All you need is to keep the drill bit in place until it makes the initial marks.

b- You can start drilling at an angle, with the edge of the drill bit making a C slot and then getting the drill bit up to vertical.

 If you have one of our sets that come with the PU case and insert, the inserts can also serve as a guide to start the hole.

Please consider using our drill guide on Amazon

Here is what one of customers said about our guide:

I was anxious about drilling into my granite countertop. The Drilax guide was easy to size to my 1 1/2" diamond hole saw. I located the hole position & locked the guide into place. Once I began drilling, I felt totally at ease that the hole saw would not skip about. Huge success, remarkable value. My confidence in accurately cutting through granite, marble or tile is very high using this guide.”

Over the years we have seen:
a- People building a mini dam around the hole with plumbers putty or similar materials.
b- Some prefer spraying water on the drill.
c- Some use running water to cool the drill bit.
d- There are people using crushed ice with cold water.
