What is a radial drilling machine?
A column rises from a base, and a radial arm that carries the drill head swings around the column and moves up and down. The head slides along the arm, so the spindle can be placed over any point within a large area. The workpiece stays clamped on the base or table while the machine positions the drill. These machines are common in fabrication shops, foundries and heavy engineering.
Radial Drilling Machine or pillar or bench drilling machine?
A pillar or bench drill has a fixed spindle position, so the workpiece must be moved under it, which suits small parts. A radial drilling machine moves the spindle over the work, which suits large and heavy parts that are awkward to shift.
What to specify when you ask for a quote
- Column diameter and arm length, which set the working area.
- Maximum drilling capacity in steel, and the spindle taper.
- Spindle travel and the distance from the spindle to the base.
- Spindle speed and feed range, and the motor power.
- Base and table size and the T-slots for clamping.
- Safety features such as arm and column clamping and guards, and the service available.
Where it is used
- Industrial MachineryDrilling and tapping in large frames and castings.
- ConstructionFabricated structures and plate work.
- AutomotiveLarge castings and housings.
Frequently asked questions
Why is it called radial?
The arm swings around the column and the drill head moves along the arm, so the spindle can reach points in a circle around the column, like the radius of a circle.
What size of hole can it drill?
It depends on the machine’s capacity, which is stated as the largest drill diameter in steel. Ask the maker for the figure for the material you cut.
Can a radial drilling machine tap threads?
Yes. Many models have a tapping attachment or a reversing spindle so that threads can be cut after drilling in the same set-up.
What should I check before buying?
Arm and column rigidity, the quality of the clamping, spindle accuracy, the range of speeds and feeds and the safety guards. A well-clamped arm is essential for accurate holes.
