The Bandsaw Swarf/Chip Brush is something that is often overlooked by bandsaw operators however is very critical to extending blade life. We published an article earlier on the importance of chip brushes.

Below we have outlined some key points on The Excision Swarf Brush Principle.

Excision Wire Wheel Principle

The Standard brush

Tightly packed Stands allows for swarf and chips to get caught – chips can sometimes be very hard material depending on what customer is cutting. If Chips remain in brush this reduces Blade life as well as brush life.

Wire wheels are made from metal and cause wear of the bandsaw blade over time.

Some plastic wheels as per above image have ‘soft’ and thin stands the bend easily and less effective for removing chips from the tooling and wear quicker

Excision Wire Wheel Principle-1-1-1

The Excision Brush

Strong Nylon Stands in 6mm diameter segments, evenly spaced to prevent the brush getting clogged with swarf.

The spacing also acts as a propelling action and the wheels tend to spin faster with momentum – meaning more effective chip removal.

The principle is to ‘flick’ the swarf/Chips off the tooth rather than ‘wipe’ it off which normally means pulling the swarf off the blade into the brush itself. This brush as it has individual clusters acts like a traditional street sweeper and ‘flicks’ the material.

High quality 0.9mm thick Nylon stands allows for longer lasting wheels as well as strong enough to remove the toughest chips.

The alternating segments causing a start/stop, start/stop using the same principle why we use variable tooth bandsaw blades.

Another bonus is that being a solid Nylon body you can drill the hole bigger or add a thread if needed.



‘We installed the Excision nylon brushes, went back to the machine to clean out the guards two weeks later, and there was nothing to clean out. Normally by this time, the drive and idler wheels would have been clogged up’ Craig - Melb
