Things to Consider before Buying a Drill Press for 80 Lower
With the above information and review of the top drill press for 80 lower, you may decide to buy one for your drilling projects.
To get a tool that will suit your needs and money, you need to consider some factors. The following are things to have in mind when purchasing a drill press;
The Head Size
Before you decide on the drill press for 80 lower, check its head size. It will help you determine the kind of material that tool can drill.
The swing is part of the head and determines how far you can enter your workpiece. The head size will also determine how far the spindle can travel down.
Different drill presses vary in speed. Check out the number of spinning spades the drill press for 80 lower you want to buy has.
Some come with fewer or more than others. Those with small and few spades like five operate at lower RPM speed, making them ideal for work in small capacities.
An 80% lower drill press with many spades like 12 to 16 consists of high RPM, making them suitable for commercial drilling projects. Before you buy your drill press, consider the kind of work you want it for.
The motor determines the capability of a drill press for 80 lower. The bigger the engine, the higher the torque. Powerful motors propel the drill press to drill holes in heavy-duty materials.
An ideal drill press should produce torque twice its motor capacity.
If you require a drill press for 80 lower to use on small projects or workpieces, a small one will work out perfectly. Large-sized drill presses are suitable for heavy projects and materials.
You also need to consider your work area space. Placing a big drill press in a small area may be inconvenient and uncomfortable, leading to poor results. Go for a tool to work and store comfortably.
A standard drill press for 80 lower comes with a small chuck, which can hold small bits. Large drill presses come with larger chucks that can accommodate significant bits.
Determine the size of the bits that the machine will use. Ask yourself if the drill press’s chuck will accommodate them.
You wouldn’t want a drill press for 80 lower that vibrates. The noise and movement can drive you nuts. But the worst result of a vibrating drill press is inaccurate drilled holes.
If you want an efficient machine, investigate whether it vibrates while drilling. If so, avoid it.
Drill presses vary in size. It depends on many factors like the motor capacity, materials used in its making, size, and brand.
Before buying any drill press for 80 lower, consider your wallet. Ask yourself whether you have the money or you’ll need to budget for it first. Is the price worth the product?
Talking of a drill press for 80 lower, do you know how to use it? If not, here is a guide on how to build your 80% lower receiver with it.
How to Complete an 80% Lower
Step 1: Set Your 80% Lower in an Appropriate Jig and Make Holes
Use the jigs’ pins to adjust the pivot with the blunt receiver’s in-line. Then make holes on the 80% lower’s back and front.
Proceed by arranging the pins and putting the 80 lower on one plate. Then place the assembly of the other plate after setting it.
Step 2: Fix the Template Holder
You shall use the holder to carry template plates used for drilling and cutting. Take the holder and put it on the receiver’s and jig’s upper side.
Then make holes on the holder’s every side using the holes drilled on the top sides of both side plates. Using a hex-head and Allen key bolts, fasten the jig to the holder.
Step 3: Fix the Pilot Hole Template
The pilot hole template consists of many holes. Use an Allen key and head screws to collect it. Then secure the ready jig assembly in the work-holding vise.
Step 4: Set the 3/8 – Inch Drill Bit and Drill Pilot Holes
You should drill the pilot holes before you cut the receiver. Use the 3/8 – inch drill bit after setting it. By plugging the holes, you will remove aluminum portions to pave the way for the entry points.
Step 5: Replace the 3/8 – Inch Drill Bit with an End Mill and Continue Cutting Deeper
You will need to cut 1.375 – inches deeper into the plate’s surface after drilling the pilot hole. Use a 3/8 – inch end mill. A stop dollar and calipers will help you manage the drill press to avoid milling.
When you finish, start drilling 2 – inches deep from the plate’s face.
Step 6: Cut the Slot for the Trigger
Replace the 3/8 – inch end mill with a 5/16 – inch end mill and put the fourth template. Then cut inside the 80% lower to create a trigger slot.
Step 7: Drill Pin Holes
When you complete the above step, replace the 5/16 – inch end mill with a 3/8 – inch. Then cut holes through the receivers on both sides.
Afterward, replace the 3/8 – inch end mill with a 5/32 – inch. Continue with the drilling to create trigger and hammer pinholes. When you finish, you will have completed your 80% lower receiver.
Sometimes you may opt to mill your 80 lower, but you’ve got only a drill press. As a result, you may wonder whether you can use a drill press as a mill. Here is the insight;
80% Lowers: Milling with a Drill Press
Drill presses do an incredible job when used to mill an 80 lower receiver. The entire process is easy when you follow the correct procedure.
It is important to note that you should cut and drill the workpiece vertically when milling an 80 lower with a drill press.
The difference between a drill press and a milling machine is not significant. You move the placement table manually to achieve a precise cut in a drill press while a milling machine is computerized.
Also, milling machines cut through metal only while you can cut various surfaces using a drill press.
If your 80% lower receiver got made with other materials that a milling machine cannot cut through, you could use a drill press as a mill.
The milling 80 lower with drill press is as simple as finishing the 80% lower blunt with a drill press. The only thing you need to do is to mill lightly to avoid the drill press from exploding or falling apart.
For safety measures when milling 80 lower with drill press conventional milling only. What happens when milling any work is that you place forces on the end mill’s sides.
The bit also receives pressure from the upper and down parts as the spinning continues. Based on the cut’s direction and work feed, the forces may push the bit down, up, or from the machine.
To achieve conventional milling, also known as up milling, ensure the cutter’s direction gets fixed on the end millrun against the fed work.
The result is a rotational force that makes the bit run into the machine. It is an important aspect, especially when using a press-tip or tapered chuck because they could be pulled and thrown out from the device.
You might think that milling aluminum out of your 80 lower receivers is faster when milled altogether, but you are wrong. Removing the aluminum bit by bit using drill bits is easier and quicker.
By drilling alone, you can remove the entire control cavity of your 80% lower. Its appearance will be no different from a commercially fabricated 80 lower.
As illustrated above, you need not worry in the absence of a milling machine when you want to mill your 80 lower. If you have a drill press, use it.
Miling 80 lower with drill press works out great. But don’t allow all these tools to confuse you. As technology develops, more innovations are born, resulting in having tools that can do more than one purpose.
That’s why you find a machine being able to carry out the task of another, like in the case of the drill press, mill, or router. Here is all about them;
Router Versus Drill Press or Mill
A router is a handheld carpentry tool used in grooving joints, decorating, or molding on workpieces. As explained above, a drill press and mill cut holes through surfaces.
All these machines use a jig to help cut through workpieces accurately. A jig comes indexed to indicate where to cut or drill your 80 lower.
The kind of jig to use depends on whether you use a router, a drill press, or a mill. When you use a router to finish your 80% lower, you will require pin and pilot holes onto your receiver.
It means that you will need the services of a drill press or mill.
Despite milling 80 lower with a drill press, the tool comes with many benefits, as explained above. But despite its usefulness, it has the following shortcoming.
Challenges of Miling with a Drill
When you mill your 80% lower receiver using plunge cuts, the end mill bit dulls quickly. You will need to replace them sooner.
The above information about drill presses may have enlightened you, but you may still have some questions. To help you answer some of those questions, here are answers to some of the frequently asked questions.
1. Can You Complete an 80% Lower with Just a Drill Press?
It is possible but will be a bit tricky to achieve accuracy. That’s why it gets recommended to use a drill press with a jig. Marking out the locations of the holes on your 80 lower with your hands is not easy.
The likelihood of messing is high. But when you follow the markings on the jig, it becomes easier. Using a drill press alone to finish your 80 lower receivers will require patience, as it will take time.
2. Can You Mill an 80 Lower Without a Jig?
Yes, you can, mainly if you use a vertical mill and read and understand dials or DROs. But as explained above, the process may be tedious and require a lot of concentration.
Besides, it’s not easy to place the cutter in the correct place, giving room to mistakes. It would be easier when using a jig.
3. What Does an 80 Lower Mean?
It is an unfinished firearm. As its name denotes, it comes only 80% complete. The blunt receiver is not serialized and cannot trigger.
It can also not fire a bullet, explaining why the BATFE (Bureau of Alcohol, Tobacco, and Firearms) does not consider the 80 lower a firearm.
4. How Hard Is It to Finish an 80% Lower?
As illustrated in the above step-by-step guide on how to complete an 80% lower, the process is easy. You only require some patience because each step requires substantial time.
When you want to build your 80 lower, look for a day when free. The fact that an 80% lower finishing process takes much time does not make it hard.
5. Can I Use Someone Else’s CNC Machine to Finish An 80% Lower?
According to federal law, it is illegal to finish your 80 lower using another person’s CNC machine. Before building a blunt receiver, it contains no serial number.
But after you finish building it, you must ensure the 80% lower gets a serial number on it. The best way to complete your 80 lower is to purchase your machine.
6. Can You Use an End Mill in a Drill Press?
Yes, you can. As illustrated earlier, you will need to use an end mill when milling 80 lower with a drill press.
The end mill will help cut the plate deeper. But the drill press’s head bearings come smaller compared to those in a milling machine.
Also, the spindle of a drill press can’t handle much sideload. You will therefore need to look for small x-y tables to bolt onto the table.
Plunge is the best method to use. It entails drilling a hole on the slot’s one end, then placing the end mill inside the chuck.
Ensure that the end mill aligns appropriately with the spot, then plunge it carefully down the hole.
Then raise the cutter and move the table. Continue cutting the workpiece by plunging the blade. Repeat the procedure until you achieve your intended slot length.
As illustrated above, a drill press for 80 percent lower is an essential tool to have when you want to finish your 80% lower receiver. The machine comes in different sizes and capacities, as explained above.
Most gun users may fear building their 80% lowers, thinking it’s a complex process. But as discussed above, the process is straightforward. What you require is patience as the procedure takes time to complete.
If you use the above step-by-step guide carefully, you will finish your 80% lower successfully.
If you want to buy one, don’t forget to keep in mind the factors discussed above. Otherwise, you will end up with a drill press not ideal for your receiver project.
You can use a drill press as a mill if you don’t have a milling machine. You only need to follow the steps discussed above.
If you are confused about what machine to buy to build 80% lower, pick one above from my reviewed list of the best drill presses for 80% lower. Ensure the machine you choose suits your needs and budget.
