A lightweight cutting tool designed for both lightweight and heavy-duty flex shafts, featuring tungsten carbide cutting teeth and hollow blades to prevent debris buildup. Ideal for removing limescale, tuberculation, roots, liners, and hardened deposits, while maintaining smooth operation through bends and junctions.

Description

The Lightweight Cutting Tool for flex shaft machines was developed from direct customer feedback and is specifically designed for use with lightweight flexible shafts, while still remaining compatible with larger systems.

Customers reported that the standard Root Cutting Tool was highly effective, but too heavy for smaller flex shaft machines. The lower torque of lightweight shafts made it difficult to maintain speed and cutting performance, especially over longer runs.

However, users discovered a key advantage. When the outer cup blade was removed, the tool became significantly lighter and easier to operate. This resulted in improved speed, better power transfer, and more consistent cutting performance.

Based on this, we are offering a dedicated lightweight version that removes unnecessary mass while maintaining cutting strength.

The tool features solid blades mounted to a central hub, secured to the flex shaft using set screws. Each blade includes a hollow channel, allowing debris to pass through the tool during operation. This prevents material from building up between the blade and the pipe wall. (An issue that would otherwise reduce cutting speed and efficiency).

The cutting teeth are made from tungsten carbide, the same material used to make excavator teeth, providing high durability and long service life under demanding conditions.

At the front, a drill-style head allows the tool to penetrate blockages before the blades expand the cutting action across a wider surface area. This creates a combined action:

  • Penetration
  • Breaking
  • Cleaning

The tool shares some similarities with a circular chain, in that it occupies a large portion of the pipe diameter. However, while circular chains are primarily used for descaling, this tool is designed for removing buildup and blockages, making it more versatile.

It can be used for:

  • Cutting roots and wood
  • Removing failed pipe liners
  • Breaking cement, mortar, and hardened deposits
  • Cleaning limescale and tuberculation
  • Restoring flow in restricted or blocked pipes

The streamlined design also improves movement through bends and junctions, reducing resistance and allowing smoother operation.

We do not recommend using this tool for removing metal rebar or other metal intrusions in a pipe. For this, we recommend that you see the Picote section on our website. (If you can not see this section on our website, then this means that your local agent has objected to us displaying it, and we recommend that you contact your local Picote dealer).

  • Compatible Shaft Sizes: 8mm (5/16"), 10mm (⅜”), 12mm (½”)
  • Design Type: Lightweight cutting and blockage removal tool
  • Blade Configuration: Three solid blades with hollow channels and tungsten carbide cutting teeth (no outer cup blade)
  • Head Type: Drill-style front head with tungsten carbide cutting teeth
  • Material: Stainless steel body, with tungsten carbide cutting elements (excavator-grade durability)
  • Mounting: Shaft hub with set screw connection
  • Applications: Drain cleaning, blockage removal, descaling, liner removal
  • Pipe Compatibility: Cast iron, clay, and similar materials (PVC with caution)
  • Performance Benefit: Reduced rotational mass for improved speed and efficiency, especially on low-torque systems

Important: Using an imperial Allen key may strip the set screws. We recommend using a metric Allen key instead.

A screw set with metric Allen keys can be found here.

The Lightweight Cutting Tool is designed for professional use with both lightweight and heavy-duty flex shaft machines, where efficient power transfer and smooth operation are critical. This is not a DIY tool and we do not recommend using any of our tools unless you are a professional drain cleaning tradesman who is qualified to use these tools.

Compatible Machines

  • Ridgid K9-204 Flexshaft: 8mm (5/16")
  • Milwaukee Flexshaft systems: 8mm (5/16")
  • Picote Flexshaft systems: 8mm (5/16"), 10mm (3/8"), 12mm (1/2")

Additional accessories such as centralizing brushes, shaft locks, and compression springs (not included) can be used to stabilize and centralize the tool during operation.

Typical Applications

  • Removing limescale and mineral buildup
  • Clearing tuberculation and corrosion
  • Breaking up cement and hardened debris
  • Cutting roots and wood obstructions
  • Removing failed liners
  • Opening heavily restricted pipes

Operating Guidance

  • Maintain consistent rotational speed for optimal cutting performance
  • Use a machine with a torque limiter to prevent shaft coiling if the tool stops suddenly
  • Allow the drill head to engage the blockage before applying forward pressure

The reduced weight improves control, reduces strain on the shaft, and allows smoother operation through bends, junctions, and longer pipe runs.
