What Are The Slots In A Drill Press Base For?

Slots are a common feature on drill presses. They are used for a variety of purposes. From lubrication to sanding, slots are crucial to a variety of tasks.

Listed below are some common uses of t-slots. We’ll also discuss lubrication and clamping.

But first, let’s talk about what these slots are and how they work.


A lot of people have never used t-slots in their drill press base, but they are actually quite useful. These slots have a cavity underneath them that holds t-bolts, and if you abuse them, they can crack. While you might not use them very often, having knowledge of these slots can open up a whole world of possibilities. Listed below are some of the reasons you should use t-slots in your drill press base.

First, you need to drill a hole through the table. Use a 3/4″-wide straight bit to make the grooves. Drill the hole until the top surface of the plug matches the center of the hole. After the hole is drilled, you need to install the guide channels and the fence, and adjust the second T-track so it moves smoothly. Once this is done, you can install the drill press.

You’ll also need to make a table platform. You’ll want to use 3/4-inch plywood that’s void-free, and you’ll want it to fit the base of your drill press. This base should have recessed holes in it for the T-track to slip into. You’ll need four recessed holes in the base platform to accommodate the T-slot mechanism, and the two t-slots must be approximately one-half-inch-deep.

The base of a drill press features t-slots on the bottom to secure work pieces. T-slots are similar to the slots on the drill press table, but they can be used for more purposes than just holding work pieces. In fact, you can even lag bolt the base to the floor! So, it’s worth the investment. If you’re looking for a way to mount jigs and vises, you should consider installing t-slots on your drill press.


If you want to do a bit of sanding but you don’t want to risk ruining your table, you should purchase an extended drill press table. These tables come with 7/8″ thick MDF/Melamine construction, adjustable fence, and a removable insert. You’ll have plenty of room to work, even with large multi-tooth forstner bits.

The drill press table is constructed of two layers of Baltic Birch plywood. It can also be equipped with a sanding drum set. These drums can turn your drill press into a sanding gun, which makes it an excellent all-purpose tool. And, if you have a lot of work, you can use the drill press for sanding, too.

The slots in a drill press base are intended for sanding, but they can also be used for other purposes. Some slots can be used for other items, such as a router. The slots can also be used for holding special items, such as router bits. For example, you can use a drill press for routing a table, and use a different router bit to do the job.


Using the slots in the base of a drill press to clamp heavy work can be a very efficient way to secure work while drilling. The table can be turned up or down and the base can be flipped 90 degrees to accommodate tall work. Alternatively, you can use a small laser level to center the table to the drilling point. In either case, the carriage bolts should be flush with the table top.

To adjust the screw in the base, first make sure the clamp toggle is closed. If it is not, use an awl to trace the slot on the back of the face. Drill a hole near the end of the slot nearest the bevel. The slot must be deep enough to accommodate 5/i6M-diameter threaded inserts. Make sure the drilled hole fits the insert properly, and don’t drill too deeply.

The hold-down clamp is made up of a plywood base that fits into the slots of a drill press from underneath. The carriage bolt passes through the base and clamp and then passes through a star knob. The clamp can slide along the bed of the drill press. The long arm offers full coverage and allows pivoting. The hold-down clamp is custom-fitted to the table of the drill press.

There are two different types of bases for a drill press. One has a T-slot table that moves along the X/Y axis, while the other has a T-track fence. The base has slots to hold clamps, while the T-track table is flexible. A drill press is a tool that will last for many years. In addition, you can buy extensions to double the width of the table.


While drill presses are equipped with a housing to protect against dust and debris, this may not be enough to keep your equipment functioning well. Dust is often fine and can get into small gaps, which lubricants use to seal. Applying lubricant regularly will ensure the slots remain closed. This lubricant also helps to reduce heat and friction, which can result in shortened drilling time.

The base of your drill press will often have slots. Each slot serves a specific purpose. In some cases, the slots will be used to attach a jig or vise. You can also use slots in the base to lag bolt it to the floor. Once installed, the slots in the drill press base will hold the machine in place. If your drill press comes with slots, you can attach a vise or jig to use while you are drilling.


T-slots are a common type of safety feature found on drill press bases. They feature a cavity underneath the slots for storing t-bolts. The holes in these slots can crack or chip if they are abused. You may never use these slots, but understanding their purpose opens up a whole new world of possibilities. To learn more about them, read on.

Safety slots are also used on general-purpose drill presses. This feature is especially important for large workpieces, which may not fit between the table and quill. As a result, the table swings out of the way when mounting work. This feature isn’t required on modern bench drill presses, but it can come in handy for mounting work. In addition, the slots in drill press bases allow you to do fixtures without having to worry about your workpiece being dropped accidentally.
