Why Rotation Matters
Blades are available in opposing rotation patterns, allowing them to be configured across the drum to:
- Reduce load on the machine
- Improve cutting stability and balance
- Increase cutting efficiency under load
- Reduce vibration and uneven wear
Using mixed rotation setups helps distribute forces more evenly across the drum, improving both performance and blade life—especially on harder concrete and deep cutting applications.
Engineer note
On CT320 / CT340 machines, incorrect blade setup is one of the biggest causes of poor performance. Running a single rotation or incorrect spacing can overload the machine, reduce cutting efficiency, and accelerate wear. A balanced drum setup with opposing rotation blades significantly improves overall performance.
Deep Joint Cleanout & Repair Preparation
Diamond blades for Contec CT320 and CT340 planers are commonly used for removal of deep, wide joints and failed joint systems prior to repair.
- Suitable for wide movement joints and construction joints
- Effective for removing:
- Failed sealants
- Resin systems (e.g. heavy-duty joint fillers)
- Contaminated or broken edges
- Allows full-width cleanout, not just centre cutting
- Ideal where joint saws are too narrow or inefficient for bulk removal

Preparation for Armoured & Heavy-Duty Joint Systems
These blades are widely used to prepare concrete floors for new joint installation systems, including armoured and interlocking joint profiles.
- Used to remove existing joints and open the full channel
- Prepares floors for:
- Armoured (armored) joint systems
- Heavy-duty industrial floor repairs
- High-traffic warehouse environments
- Ensures proper bonding and long-term performance of new joint systems
Engineer Insight
Blade selection and setup are critical on CT320 / CT340 machines. Incorrect spacing or bond type can lead to rapid wear or poor cutting efficiency, particularly on hard concrete or where steel edges are present.
On deep or wide joints, a planer setup allows full-width removal and consistent depth, ensuring proper preparation before repair systems are installed.
Important
These blades are designed for bulk removal, surface preparation, and joint cleanout prior to repair systems.
