- It is a flexible drilling machine, ideal for large workpieces.
- It is powerful and best suited for heavy-duty materials.
- It provides precision drilling.
Disadvantage
- The cost of a radial drilling machine is higher.
- It can occupy a lot of space.
Suitability
- It is best suited for large-scale, heavy-duty industrial operations such as metal fabrication, construction, and shipbuilding.
3. Gang Drilling Machine
These are multi-drill machines with multiple drills mounted on a single table. When the spindle rotates, all the drills rotate at the same speed to drill the workpiece.
Advantages
- It provides precision, as there is no need to move the workpiece much.
- It can drill identical holes in multiple workpieces at the same time.
- It is a high-precision and efficient drilling machine.
- It takes less time to do different drilling processes.
Disadvantage
- The cost of a gang drilling machine is higher.
- It can occupy a lot of space.
Suitability
- It is suitable for manufacturing processes and high-volume drilling applications.
4. Portable Drilling Machine
These drilling machines are most handy because they provide portability. They can be hand-held or small table-mounted. Portable drilling machines are versatile and compatible with materials such as wood, plastic, and metal.
Advantages
- It is easy to handle and operate.
- It is lower in cost compared to other industrial drilling machines.
Disadvantage
- It is not suitable for heavy-duty drilling operations.
- It offers lower precision compared to other drills.
Suitability
- It is best suited for low-scale daily drilling operations.
- It is suitable for small workshops or on-site jobs.
5. CNC Drilling Machine
These drilling machines are automated with computer numerical control to perform drilling operations with high precision and efficiency. CNC drilling machines minimise human intervention, thereby saving time for manual efforts. The dimensions are fed through a CNC system, and the drill is automated to work on the material.
Advantages
- It is a high-speed, accurate and precision drilling machine.
- Using CNC drills saves time and manual labour.
- It offers versatile applications.
Disadvantage
- It is costly and requires trained personnel to operate it.
Suitability
- It is suitable for large-scale industrial operations.
- It is ideal for defence, automotive and aerospace applications.
6. Deep Hole Drilling Machine
These drilling machines are used for drilling narrow, deep holes in the workpiece. These drills are specifically designed for deep drilling, ensuring precision and no damage to the workpiece. It consists of a long and slender drill to make vertical or horizontal deep holes.
Advantages
- It is best to drill narrow holes, preventing damage to the material.
- It has high accuracy and is ideal for heavy-duty drilling.
Disadvantage
- It offers specific use for drilling narrow holes.
Suitability
- It is suitable for industrial applications in oil and gas, automotive, aerospace, etc.
7. Multi-Spindle Drilling Machine
These drills are designed to create multiple holes in different locations on the workpiece. The multi-spindle drilling machine consists of multiple spindles on a single mount. These drills are ideal to drill multiple holes with precision.
Advantages
- It is an accurate, time-saving drill machine.
- It offers versatile applications.
Disadvantage
- It is costly and requires trained personnel to operate it.
Suitability
- It is best suited for fabrication, furniture making, automotive and mass production.
8. Sensitive Drilling Machine
These drills are best suited for precision drilling; hence, they are also known as precision drilling machines. These drills are used for miniature drilling where accuracy is of utmost importance.
Advantages
- It is a lightweight and compact drill machine.
- It is less expensive than other drilling machines.
Disadvantage
- These drill machines are not suitable for heavy-duty applications.
- It requires trained personnel for accurate drilling.
Suitability
- It is suitable for small-scale industrial processes.
- It is suitable for the electronic and electrical industries.
9. Micro Drill Press
It is a portable drill machine which is used for small scale drilling needs such as prototype building, jewellery making, etc. Micro drills consist of smaller spindles and lesser speed.
Advantages
- It offers precision and clean drills.
- It offers versatile applications even with a compact design.
Disadvantage
- It is not suitable for heavy-duty applications.
Suitability
- It is suitable for fine crafting, electronics, and prototype making.
10. Turret Type Drilling Machine
These drilling machines have a turret that holds multiple drilling tools that can be used on a need basis. These drilling machines have versatile applications providing accuracy and precision.
Advantages
- It is best for multi-step drilling processes, reducing downtime between tool changes.
- It is more cost-effective than other drilling machines.
Disadvantage
- It may require regular maintenance and skilled personnel to operate.
Suitability
- It is suitable for manufacturing and machining applications.
