Metal Cutting Circular Saw Machines

Circular cold saws for burr-free metal cutting

A circular cold saw cuts tube, structural shapes and solid bar with a toothed blade under flood coolant. The heat leaves in the chip, not the part, so the cut stays cool and the face comes off square, bright and nearly burr-free. Shops call the design a cold saw for that reason, and also a metal cutting circular saw machine. KNUTH offers manual stationary cold saws in two sizes for small and mid-size sections.

Cold saw, abrasive chop saw or bandsaw: how they differ

Three kinds of machine part metal, with different results:

• Circular cold saw: toothed blade, slow spindle, coolant. A bright square face, minimal kerf loss, no heat discoloration. The pick when the face goes straight into a weld or stays visible.
• Abrasive chop saw: a consumable disc at high speed, no coolant. Cheap to buy, and you pay in sparks, dust, heat and grinding afterward.
• Bandsaw: a continuous band. It owns heavy solid bar, long cuts and self-feeding production runs.

A fab shop working tube and shapes all day gains on cycle time and on finish with a cold saw. Heavy solid stock and automatic-feed production belong in the industrial sawing machines lineup instead.

Manual or semi-automatic: picking the right cold saw

The dividing line is how much of the cycle the machine handles. On a manual cold saw the operator brings the head down on a lever, hears the cut and switches jobs with no setup. That fits maintenance, one-offs and short runs. A semi-automatic circular cold saw machine adds hydraulic downfeed and air clamping, which pays off when one length is wanted by the hundred. KNUTH lists both grades in this category, so you can start manual and step up when volume justifies it. If your part runs in full production volume, tell us the length and quantity and we will say whether an automated bandsaw is the honest answer.

Blades and materials

Blade choice drives finish and blade life more than anything else. Mild steel and structural work run on HSS blades. Stainless wants a finer pitch and a slower surface speed. Aluminum, brass and copper want their own tooth form and a faster speed. Keep several teeth engaged in a thin tube wall, and go coarse and strong on solid bar. We stock the matching circular saw blades and other accessories.

Where cold saws earn their keep

• Job shops and weld shops: square, weld-ready ends on tube and angle, no second operation
• Steel service centers: stock bar and shapes cut to customer length
• Machine builders: repeatable blanks for fixtures and weldments
• Plant maintenance: a quick, clean cut when a line is down
• Trade schools and training programs: simple controls, and the miter cut as a lesson

Machine sizes and features

Cold saws are separated first by cutting capacity, the biggest section taken at square and at an angle. Then come blade diameter, motor rating, cutting speed and equipment such as the coolant pump, length stop and floor stand. Both KNUTH sizes miter left and right, with the angle read off a scale and locked against a swivel stop. Capacities for the sizes currently offered are in the product cards above.

Why KNUTH

KNUTH is an established supplier of machine tools, with sawing covered from the cold saw through to the bandsaw. The machines are built to European testing standards and we send the documentation on request. Stock ships from our warehouse near Chicago, with blades and tooling from the same source. European build quality, parts and support in the Americas.

Service, spare parts and lead time

Our Americas service team supports the full KNUTH range. Wear and spare parts ship from our own inventory, special parts direct from the manufacturers, and a ten-year spare parts availability guarantee applies. Setup, start-up and operator instruction we offer as services, quoted with the machine. Details are on maintenance services and on repairs and spare parts.

Other saws in the KNUTH lineup

Cold saws are one part of the saw program. Angle work in heavier sections goes to a horizontal metal cutting bandsaw, straight production cut-off to an industrial stationary bandsaw. A shape cut out of plate or an inside contour calls for a vertical metal bandsaw.
