The Nargesa BM25 is a vertical hydraulic broaching machine that cuts internal keyways from 2 mm up to 25 mm (1") in sprockets, pulleys, gears and bearings. Its 300 mm neck takes parts up to 600 mm in diameter, and setup takes about a minute, so it suits machine shops doing small and medium production.

Applications
The BM25 is designed for internal broaching applications where accurate keyways or profiles need to be produced in pre-drilled components.
Typical applications include:
- Keyway machining
- Sprocket keyways
- Pulley keyways
- Gear keyways
- Bearing and bushing machining
- Internal slots and grooves
- Square internal profiles
- Rectangular internal profiles
- Hexagonal internal profiles
- Multiple keyways from a single bore
- Repair and maintenance machining
- Replacement-component manufacturing
- Small production runs
- Medium production runs
- General hydraulic pressing
- Bearing and bushing installation and removal
- Seized-component removal
- Straightening operations
The BM25 is particularly useful for maintenance and machine shops where internal keyways may be required regularly but investing in a large CNC broaching system would not be practical.
Why Choose the Nargesa BM25?
The BM25 provides a practical alternative to more complex machining equipment when the primary requirement is producing internal keyways and profiles.
Its 10-ton hydraulic system, 25 mm broaching capacity and 600 mm stroke provide substantial machining capability while maintaining a relatively compact footprint. The quick setup and manual controls also make it suitable for both repeat production and one-off repair work.
Another advantage is its versatility. When it is not being used for broaching, the BM25 can be used as a 10-ton hydraulic press, allowing the same machine to perform additional maintenance and fabrication tasks.
Key advantages include:
- Accurate internal keyway and profile machining
- 10 tons of hydraulic force
- Up to 25 mm (1") broaching capacity
- Fast approximately one-minute setup
- Simple manual operation
- Large 600 mm stroke
- Large 300 mm throat depth
- Supports workpieces up to approximately 600 mm diameter
- Metric and imperial tooling compatibility
- Versatile hydraulic press functionality
- Compact workshop-friendly design
- Suitable for production and maintenance applications

Frequently Asked Questions
What keyway sizes can the BM25 cut?
From 2 mm up to 25 mm (1"). Nargesa supplies broaches in metric and American standard sizes.
What power does the BM25 need?
Nargesa specifies a 2.2 kW (3 HP) motor on a 230/400 V three-phase supply. Confirm your shop’s voltage with BTH Sales before ordering.
Can it do more than broaching?
Yes. Nargesa says it also works as a press for freeing seized parts and fitting or removing bearings.
How big a part can it handle?
The 300 mm neck takes parts up to 600 mm in diameter.
How long does delivery take?
BTH Sales ships across Canada from St. Marys, ON. This machine has a 4–6 week lead time; contact us for an exact date.
