In this post, we’ll explain what a drilling machine is, what types of tasks each kind of equipment is best for, and how these machines operate. Plus, we’ll give you tips on what to look for when buying one and how much to expect to spend on high-quality gear.
What is a Drilling Machine and What is it Used For?
The primary purpose of a drilling machine is to create precise holes in tough materials like wood, metal, or plastic.
People often purchase a drilling machine for garages or workshops to handle tasks like:
- Drilling hinge holes for cabinets, doors, handles, and fittings.
- Drilling bolt holes for metal items like outdoor furniture, swings, and bicycles, or screw holes to securely assemble the furniture.
- Drilling pipe, cable, and wire holes for electrical wiring, plumbing, or outlets.
- Drilling decorative holes for installing hooks, shelves, and ventilation in cabinets and boxes.
How a Drilling Machine is Structured and Works
A typical drilling machine consists of six key parts:
- A solid and stable foundation where all components are mounted.
- Rotating shaft (spindle) where the drill bit attaches.
- Sharp-tipped drill bits of various sizes, which serve as the primary tool for creating holes.
- Feed mechanism controlling the depth and speed of the drilling process.
- Motor powering the spindle and the attached drill bit.
- A workholding table.
How a Drilling Machine Works
The first step is to securely fasten a wooden, metal, or plastic workpiece on the machine table.
The second step is to select a drill bit with the required diameter and carefully attach it to the spindle.
The third step is to start the engine and gently lower the spindle, along with the rotating drill, onto the workpiece.
Important: The drill rotates at a very high speed, so it’s crucial to choose the correct bit and set the appropriate revolutions carefully. Otherwise, the tool may break or the material could overheat.
Depending on your intended use, there are several types of drilling machines. The table below will help you choose the right machine for personal or professional work.
Types of Drilling Machines
| Machine Type | Characteristics | Advantages | Examples of Use |
| Tabletop | Compact, mobile, low power | Easy to use, ideal for home projects in small workshops | Drilling holes for shelves, installing hooks, repairing bicycles, crafting |
| Vertical | Stationary, high power, high precision | Suitable for working with hard materials, drills even and deep holes | Furniture production, automotive industry, metalworking |
| Radial | High precision and speed, movable spindle | Ideal for drilling complex parts at different angles, used in industry | Manufacture of aircraft, machine parts, building structures, tools, watchmaking |
| CNC | Automated, computer-controlled, high precision and speed | Perfect for mass production, enabling the manufacture of a large number of identical parts | Manufacture of electronics, medical equipment, and automotive parts |
Which Drilling Machine to Buy
When choosing a drilling machine, you should consider its type, power, rotation speed, and any additional features. Here’s a closer look at what to keep in mind.
Type
If you need a machine for occasional use and simple household tasks, a tabletop model is your best bet. For those starting or running a small production, vertical drilling machines are ideal.
Not sure which drilling machine to buy for making complex parts? Consider radial models, designed specifically for this purpose, offering exceptional accuracy.
For large-scale production, choose CNC drilling machines. They are designed for mass production with precise parameters, are computer-controlled, and are ideal for automating processes at an enterprise.
Power
A machine with a power of up to 500 W is sufficient for working with plastic and wood. For drilling thin metal, you’ll need a machine with 500-1000 W of power. For durable materials and thick metal, opt for a drilling machine with more than 1000 W.
Rotation Speed
Low-speed machines are best for drilling thin, hard materials without overheating, while high-speed machines are more suitable for soft materials.
Additional Features
When choosing a drilling machine, consider additional features based on your specific tasks.
Additional Features of a Drilling Machine
| Category | Feature | Advantages |
|---|---|---|
| Feed System | Automatic feed | Enhanced drilling accuracy and high-quality holes |
| Feed speed adjustment | Optimal drilling speed depending on the material and drill diameter | |
| Drilling depth locking mechanism | Precise control over drilling depth for parts with specific parameters | |
| Table | Rotary table | Facilitates angle drilling |
| Height-adjustable table | Useful for working with parts of varying sizes | |
| Table extensions | Expands the working area, making it possible to drill larger parts | |
| Spindle | Adjustable rotation speed | Optimal drilling speed based on material and drill diameter |
| Tightening torque control | More precise and controlled drilling | |
| Replaceable chucks | Enables the use of drills with different diameters without additional tools | |
| Other Important Functions | Cooling system | Prevents overheating of the drill, extending its service life |
| Swarf conveyance system | Maintains cleanliness at the workstation and prevents mechanism clogging | |
| Laser pointer | Accurate determination of the drilling location | |
| Digital display | Shows machine operating parameters such as speed, drilling depth, and more. | |
| Safety | Protective screen | Shields the operator from swarf and other debris |
| Emergency stop | Allows for immediate halting of the machine in case of an emergency |
How Much Does a Drilling Machine Cost?
The answer to the question “How much does a drilling machine cost?” varies based on the type, brand, power, additional features, and configuration of the equipment.
As of August 2024, the price ranges approximately as follows:
- Tabletop machines: Prices range from €50 to €500.
- Vertical equipment: Costs between €200 and €2,000.
- Radial machines: Price ranges from €1,000 to €10,000.
- CNC machines: The most expensive, costing between €5,000 and €50,000 per unit.
Prices frequently fluctuate not only based on the model and brand but also depending on the seller. Therefore, we recommend comparing multiple offers before making a purchase. Additionally, be aware that the total price may not include delivery costs or many components and accessories.
