Everything You Need to Know About Best Countersink Drill Bits

The Most Important Things in A Nutshell

  • Column drills are more precise: they can create a hole perfectly aligned with the angle you need.
  • They are also more efficient and faster, especially for repetitive tasks. Column drills can pierce a wooden surface or a piece of iron very easily, saving time to finish the job.
  • The column drills, in addition to being very powerful, have various speeds that allow greater control by those who use them.

Buying Guide

Thanks to advances in technology, column drills are now accessible for almost any budget. Until a few years ago they were an exclusively professional tool: today, however, with a small investment you can have one in your workshop. To understand what they are and how they work, we have developed this buying guide for you.

What Is a Countersink Drill Bits?

Column drills, also called bench or vertical drills, are tools for stationary drilling with vertical movement. The drill is placed on a table or workbench, attached to a column, with a movable axis that moves up and down. It has a base to support the piece on which it is being worked.

Bench drills are very precise tools that allow you to get clean and deep holes, excellent for working on delicate materials or very large surfaces. In addition, they are widely used in workshops where serial work is carried out, although there are currently versions suitable for domestic use.

What Are the Advantages of A Drill Press Compared to A Manual Drill?

Initially, these tools were exclusive to workshops, since they were very large machines, with powerful engines and an important cost. They were designed for demanding and professional jobs or for mass production, such as the manufacture of mechanical parts.
Today, however, the column drills are within everyone’s reach and offer a series of advantages compared to the classic electric drill.

  1. Precision Much more precise than manual drills. They allow to drill at an angle without input errors.
  2. Speed The movement of the spindle allows you to quickly carry out serial work.
  3. The rack lever offers a significant mechanical advantage.
  4. Power Manual drills have limited power.
  5. Column drills allow you to adjust speed and power.
  6. Precision The spindle allows you to set the drilling depth.
  7. Both the depth and the drilling angle can be adjusted.
  8. Safety Manual drills can slip.
  9. Column posts are more stable.
  10. They allow you to fix the piece on which you are working on the worktop with screws.

How Does a Countersink Drill Bits Work?

The column drills belong to the group of vertical drills, the simplest and most accessible among the various types of drills on the market. They are characterized by the presence of a vertical spindle, supported by a “C” shaped frame, in a fixed position, which moves by rotating.

Handling a drill press is very simple, since there are only two main movements:

Rotation of the cutting tool (drill tip) – is caused by the electric motor of the machine, which transmits it through pulleys and gears.

The penetration of the drill bit into the surface being worked on – can be done manually or automatically. Just this movement, and the simplicity with which it occurs, makes the difference between the two main types of drill press.

What Are the Components of A Countersink Drill Bits?

All drill presses have a series of basic components: a column, a base, a perforating tip with motor and accessories, a work table and a crank. Additional elements may be present, depending on the type and complexity of the tool.

In the following section, we explain the parts and components of a drill press, so as to help you better understand its operation:

  • Base or support plate: it is the support of the machinery. Offers stability and rigidity for column mounting. Generally built-in cast iron, it can withstand vibrations and is equipped with holes to screw it to the work table or the floor. It contains slots for fixing screws and clamps.
  • Column: of cast steel, it is the main component of the machinery and rises from the base. Most of the elements are mounted on the column, such as the worktop and the drill bit. It can be case-shaped, round or tubular (the latter being the most common design).The height of the column is that which determines whether we are faced with a column drill (therefore a bench drill) or on the floor.
  • Worksurface: round or rectangular, it is used to position the pieces we want to work on. The surface is rectangular and perpendicular to the column, and can be raised, lowered or rotated around it by means of a set of handles and hinges. In some models, it is tilting.
  • Drill head: mounted on the top of the column, it is the one that contains the mechanism that allows the bit to rotate and perforate the piece. The mechanism consists of a spindle and a starter motor connected via a V-belt and stepped pulleys in the upper part of the tool.

How Best to Maintain a Countersink Drill Bits?

Like all tools of a certain complexity, from the cheapest to the most sophisticated model, the bench drill requires some maintenance, which in the case of the column drill is simple, but essential. Here are some tips to make it better:

Lubrication of a drill press is important, as its moving parts overheat and generate friction. Therefore, we must check the lubrication methods suggested by each manufacturer.

Always clean the drill carefully after each use, paying particular attention to the slots and holes in the base plate and to the transmission and starting elements.

Make sure to remove splinters and debris from belts, pulleys, spindle and handle, to avoid damage to moving parts.

Once cleaned, pass a layer of oil on all the unpainted surfaces to avoid oxidation and corrosion.

If the tool is used in a carpentry shop, where a lot of dust is raised, it is good to use it at low speed to prevent the moving parts from wearing out due to abrasion, and lubricate it more often.

In extreme cold conditions, it is advisable to start the appliance at low speed and allow the parts and the lubricant to warm up a little before increasing it.
With the extreme cold, the metal becomes fragile, so you must avoid hitting it. In extreme heat, however, the engine may overheat and melt, so it is best to use the machine intermittently.

Purchase Criteria

If you are a DIY enthusiast, if you love to do your own work or dedicate yourself to carpentry and construction, your tools are your best allies: you must, therefore, choose the most performing and functional ones.

You will find a large variety of drill presses on the market. To help you choose the one that’s right for you, here are some important purchase criteria to follow:

  1. Power
  2. Speed ​​regulator
  3. Height adjuster
  4. Screen and laser

Power

Power is particularly important in column drills, as the final performance of the tool will depend on it. In this type of machine, the power should not be less than 400 or 500 W for carpentry or construction work, to guarantee precise holes and a professional result.

Likewise, a high power will allow you to work with materials of varying hardness, taking advantage of the versatility of the appliance to effectively drill wood, steel or plastic. However, a lower power drill (200 W, for example) will suffice for any home DIY project.

Speed ​​regulator

It is important that your drill has a speed regulator to allow you to control the rotation speed and adapt it to each material you work with. Using a specific type of tip at a specific speed can give you excellent results in some situations but, with other types of work materials, merge the tips and the motor.

You will find on the market models with adjustable speeds up to 12 different modes, to control the power at each job you do. Do not underestimate the importance of this element, because adjusting the speed incorrectly can mean damage to the tip but also to the drill motor.

Height Adjuster

Your drill press must also have a height adjustment system. Most of the models have a moving surface whose height and, in some cases, the inclination can be adjusted. This will allow you to work more comfortably, changing the depth and drilling diagonally or at an angle.

In addition, the height adjuster will help you relieve tension on your back and shoulders, avoiding neck pain after using the tool. Obviously, models with these extra features will have a higher price.

Screen and Laser

Most bench drills you find on the market use analog pulley systems to change speeds, which are not always 100% reliable. The newer ones, on the other hand, use a digital screen to set speeds precisely, through a simple and efficient interface.

In the same way, there are some models with integrated laser, which helps to drill, especially if it comes to holes in series, quickly and easily, checking the level of perforation for each material on which you work. These additional features will also affect the price of the machine.
