Bandsaw machine

Perform regular checks on

  • Chip brush function
  • Coolant function and concentration
  • Wear and tear and alignment of the bandsaw blade guides
  • Band tension
  • Band speed

Coolant & Cutting Fluid

The coolant lubricates, cools and transports the chips out of the cutting duct. Important:

  • Sawing thick-walled tubes and solid materials necessitates the dissipation of heat when using HSS tools. Otherwise, the generation of heat will cause the tool to warp. Structural modifications of the tooth tip, which directly result in the tool becoming blunt, may also occur. The use of emulsions is therefore essential in such cases. The WESPA IPC® coolant (IPC®cooling lubricant concentrate) enables the bandsaw blade to achieve a long service life. Sawing is not only about cooling; lubricating the band is also crucial. A good coolant must also add a lubricating film to the bandsaw blade to prevent built-up edge formation. The lubricating effect is also important for ejecting the chips to enable the chip chambers always to remain clean. There is usually no cooling when carbide tools are used. However, care must be taken here to ensure that chip removal brushes are used. You can find WESPA lubricants and spray oils here



  • Make sure that the workpiece to be processed has been securely clamped and cannot vibrate or rotate.
  • Do not use damaged, bent or severely deformed workpieces.
  • The closer the positioning of the bandsaw blade guides to the workpiece, the more exact the cut will be.

Observe the running-in period


  • Observe our running-in advice.
  • Use the recommended cutting parameters to achieve optimum service life.

Optimum chip formation

  • Very fine and powdery chips point to the cutting pressure being too low.
  • Thick, strongly compacted or blue-coloured chips indicate that the bandsaw blade is being overstressed.
  • Loosely coiled chips are a sign of ideal cutting conditions.
  • Thin or powdery chips - increase the feed rate
  • Loosely coiled chips - correct cutting values
  • Thick, heavy or blue chips - cutting values too high

 Band Tension


Checking Band Tension

A long blade life and precise cutting behaviour are conditional upon an optimum band tension. WESPA's band tension measuring device allows you to provide an optimum setting for your bandsaw machine's clamping pressure and to monitor it accordingly.

We recommend a band tension of 250-300 N/mm² for WESPA bandsaw blades. This will avoid band breakage due to excessive band tension or cut deviation due to insufficient band tension.

Advice on running in bandsaws is available here.


 Toothing Pattern


Choice of Toothing Pattern

To achieve the best cutting results, it is important to select the correct tooth pitch. The tooth pitch results from the engagement length of the bandsaw blade. If the tooth pitch is too small, this can cause cut deviations, as chips clog the cutting catches and the bandsaw blade is forced from its cutting line.

If the tooth pitch is too large, this may lead to broken teeth, as the cutting pressure on an individual tooth becomes too great. At least 3 teeth should be engaged for a cost-efficient result to be achieved. Selection of the correct toothing pattern.


 Tooth Forms


To achieve the best possible cutting performance, not only steel grade, but also the number of teeth and the shape of the cutting edge are important. The geometrical form of the cutting edge and the gullet depends on the material to be cut and has a significant influence on a saw's cutting behaviour. .

To meet your cutting requirements, we offer you four tooth forms:


Standard (S)

SRake angle 0°: completely rounded gullet. For universal applications involving small to medium solid cross-sections, tubes, plates, contour sawing.



Rake angle 0°: small tooth height, flat gullet. Recommended for sawing brittle materials with relatively large cross-sections, such as bronze, brass, zinc, aluminium risers, brittle plastics.



Positive rake angle: with rounded gullet. Advantageous when sawing long-chip materials, e.g. NF metals, steels with low carbon content, materials with large cross-sections, metallic materials that tend to work-harden when sawn.


Variable tooth S and plus

VToothing pattern with 0° (S), positive (plus) or extremely positive (super plus) rake angle: constantly recurring tooth groups, whose teeth have a varying pitch within a group and are hence higher. Disturbing vibrations are reduced, with a positive impact on noise level, cut surface quality and service life.

Applications for this toothing pattern are universal, ranging from layer-cutting and bundle-cutting through to large solid cross-sections of a wide variety of metallic materials.




To achieve free cutting of the bandsaw blade in sawing operations, individual teeth are alternately deflected from the blade plane. The set type depends on the material cross-section to be cut, the material form and the material grade.


Standard set

Suitable for sawing all materials if at least 3 teeth are engaged at the same time. Range of application: starting from 5mm.


Right-left set

For sawing soft materials (NF metals, plastics, wood)


Wavy set

A special set for the thinnest material cross-sections up to 5 mm, e.g. thin-walled tubes, structurals, plates etc.

Variable tooth set

Variable tooth set

The groups of teeth recurring over the band length have one or more straight teeth (raker teeth) per tooth group, whereas the remaining teeth are set to the right and left.




Please heed the following safety advice when handling WESPA metal bandsaw blades:

  • Always wear gloves and goggles when unpacking or assembling bandsaw blades.
  • Do not remove the tooth guard until the bandsaw blade has been completely mounted on the machine. During maintenance activities, use the main switch to switch off the machine. Please comply with the machine manufacturer's safety regulations at all times.
  • Defective bandsaw blades, with cracks or missing teeth, for example, or those that have changed their form must not be used.
  • Bandsaw blades must not be arrested by lateral pressure on the bandsaw blade structure.
  • The bandsaw blade must be clamped before the machine is switched on.
  • Make sure that bandsaw blade selection and speed are suitable for the material to be cut.


  • The bandsaw blade will become hot during operation. Do not touch it, let it cool down first.
  • Always be aware of the hazard area around the operating bandsaw blade. Never reach for or grab a workpiece that you are sawing. Re-sharpening will void warranty and product liability.
  • Follow special safety regulations when re-sharpening bandsaw blades.
  • Secure re-sharpened teeth by means of a tooth guard.
  • Any unauthorized resale at auctions, on Internet platforms or in Internet shops will void warranty and product liability.
