Band saw or circular saw for bar cutting?

Circular (cold) saws cut faster and with a better finish on smaller sizes in high production; band saws handle large diameters and bundles with less waste and lower blade cost.

What capacity band saw do I need?

Choose by the largest round and rectangular section you cut, with some margin. A 250–300 mm (9.84–11.81 inch) horizontal band saw covers most general workshop bar cutting.

Band saw machine for metal: types, capacity, uses

A band saw cuts metal with a continuous toothed blade running around two wheels. In workshops it is mainly used to cut bars, pipes and sections to length before machining or fabrication. Automatic band saws feed the bar and cut many pieces to the same length without an operator.

Quick facts

Types: Horizontal (cut-off), vertical (contour), automatic, double-column
Capacity: Given as max round and rectangular size, e.g. Ø300 mm (11.81 inch)
Length accuracy: About ±0.2–0.5 mm (±0.0079–0.0197 inch) on automatic saws
Blades: Bi-metal for most steels; carbide for hard or large work
Kerf: About 1–2 mm (0.0394–0.0787 inch)
Coolant: Used for steel to protect the blade

Choosing a blade

More teeth per inch for thin walls and small sections; fewer for large solids
Bi-metal (M42) blades for general steels and stainless
Carbide blades for hard steels, nickel alloys and high production
Correct speed and feed matter more than blade price

Typical work

Cutting bar stock to length for CNC turning
Cutting pipes, angles, channels and beams for fabrication
Cutting blocks from large rounds and flats
Contour cutting (vertical saw)

Limits

Cut faces need facing or machining for accurate work
Very hard material wears blades quickly
Bundle cutting needs firm clamping to stay square
