Introduction
Railway maintenance demands precision, speed, durability, and dependable abrasive performance. From cutting damaged rail sections to removing excess weld material and preparing metal surfaces, every maintenance operation requires the right abrasive solution.
CUMI Abrasives provides application-focused cutting and grinding solutions designed to support demanding industrial operations. CUMI Rail Cut is engineered specifically for rail cutting, while CUMI Snagging Wheels are designed for aggressive material removal and heavy-duty grinding applications.
Using the right wheel for the right railway maintenance operation can help maintenance teams improve productivity, optimize wheel consumption, and reduce unnecessary operational downtime.
What Are Rail Cutting Wheels Used for in Railway Maintenance?
Rail cutting wheels are abrasive cutting wheels designed to section railway rails efficiently and accurately. They are used during rail repair, replacement, maintenance, and other operations where a rail section needs to be cut.
Typical applications include:
- Cutting damaged rail sections
- Rail replacement
- Rail repair operations
- Cutting rail to required lengths
- Track maintenance
- Heavy-duty rail cutting

- Maximum operating speed of 4,400 RPM
CUMI also identifies the Rail Cut as an RDSO-approved product, with CUMI included in the RDSO-approved vendor category list.
What Are Snagging Wheels Used for in Railway Maintenance?
Snagging wheels are heavy-duty grinding wheels designed primarily for high material removal rates. They are used where large amounts of unwanted metal need to be removed quickly through rough grinding.
Potential applications relevant to railway and metalworking operations include:
- Weld material removal
- Weld dressing
- Heavy stock removal
- Removal of burrs and excess metal
- Surface preparation
- Rough grinding
CUMI’s snagging wheels use specially formulated resins and toughened abrasive grains, with reinforced bores designed to withstand demanding high-speed grinding applications.
How Can CUMI Rail Cutting and Snagging Wheels Improve Railway Maintenance Efficiency?
Efficient railway maintenance depends on completing multiple operations within limited maintenance windows. Matching the abrasive wheel to the operation can help streamline this process.
1. Faster Rail Cutting
CUMI Rail Cut is engineered for fast and smooth rail cutting. According to CUMI, the product can achieve a cut in approximately four minutes and deliver up to six cuts in 90 UTS, 60 kg rail under the specified conditions.
This type of cutting performance can help maintenance teams complete rail sectioning more efficiently.
2. Efficient Material Removal
CUMI Snagging Wheels are designed around aggressive material removal, making them suitable for demanding rough-grinding operations.
This can be particularly useful where excess weld or unwanted metal needs to be removed before subsequent finishing or inspection.
3. Reduced Operational Interruptions
Using application-specific abrasive wheels can help reduce unnecessary wheel changes and interruptions during maintenance work.
The objective is not simply to select a low-cost wheel, but to identify a wheel that provides the appropriate combination of:
Cutting performance + wheel life + material removal + productivity
4. Consistent Cutting and Grinding
CUMI’s Rail Cut uses premium abrasive grains, a special bond, and fibre mesh reinforcement, while its snagging products use toughened grains and resin systems developed for demanding grinding environments.
How Are Rail Cutting and Snagging Wheels Used Together?
Rail cutting and snagging wheels can support different stages of a railway maintenance workflow.
Railway Maintenance Workflow
Inspection → Rail Cutting → Rail Repair/Replacement → Welding → Weld Material Removal → Surface Preparation → Inspection
Stage 1: Inspection
The rail is assessed to determine whether repair, replacement, or sectioning is required.
Stage 2: Rail Cutting
A suitable CUMI Rail Cut can be used to section the rail during repair or replacement operations.
Stage 3: Repair or Replacement
The required rail section is repaired or replaced according to the maintenance procedure.
Stage 4: Welding
Where applicable, the rail sections are joined using the required welding process.
Stage 5: Weld Material Removal
A suitable CUMI Snagging Wheel can be used for aggressive grinding and removal of excess material where the application and equipment call for it. CUMI’s snagging range includes solutions for rough grinding and welded-joint applications.
Stage 6: Surface Preparation
The repaired area can then undergo the required surface preparation and finishing operations.
Stage 7: Final Inspection
The completed rail section is inspected before returning the track to service.
This is why rail cutting wheels and snagging wheels should be viewed as complementary abrasive solutions rather than interchangeable products.
