The Nargesa PI85 is a hydraulic press that punches the lock case, handle and keyhole openings in a tube in one fast, accurate operation. Nargesa patented it in 2006 and says it fits 85% of lock brands and models, so it suits gate and door fabricators who fit many locks.

Features and applications
Key Features
- Approximately 58-second cycle time – Completes the lock preparation process significantly faster than conventional manual fabrication.
- Designed for approximately 85% of lock models – Accommodates a broad range of common lock configurations.
- Two dedicated working stations – Separates lock mechanism punching from cylinder and handle punching.
- Processes tubing from 35 × 35 mm to 50 × 80 mm – Covers many common square and rectangular tube sizes used in door and gate manufacturing.
- Supports 1.5 mm and 2 mm wall thicknesses – Dedicated tooling is available for common production materials.
- Mild steel, galvanized steel and stainless steel capability – Provides flexibility for different fabrication requirements.
- Internal tube support – Helps prevent deformation during the punching process.
- Adjustable lock entrance position – Allows adjustment from 18 to 37 mm for different lock configurations.
- Adjustable lock mechanism opening – Allows the machine to be configured around the lock being installed.
- Multiple punching configurations – Can punch the mechanism, cylinder and handle openings in different combinations.
- Repeatable positioning – Integrated stops help maintain consistent opening locations across production runs.
- Reduced manual finishing – Minimizes the need for drilling, grinding, filing and rework.
- Ready-to-install results – Produces precise openings designed to simplify lock installation.
- Safety foot pedal – Allows hands-free cycle activation while the operator positions and supports the tubing.
- Production-focused design – Well suited to repetitive door, gate and tubular steel fabrication.
- Palletized lower base – Makes the machine easier to position within the workshop.
- Fully assembled delivery – Reduces installation and setup requirements.
Applications
The Nargesa PI85 is designed primarily for manufacturers working with square and rectangular steel tubing where consistent lock preparation is required.
Typical applications include:
- Metal doors
- Security doors
- Pedestrian doors
- Entry gates
- Large gates
- Fence gates
- Security barriers
- Metal grilles
- Architectural metalwork
- Tubular steel structures
The PI85 is particularly valuable for repetitive production where the same lock openings must be created across multiple identical frames.
The machine can perform several different punching configurations, including:
- Lock mechanism, cylinder and handle openings on both sides
- Lock mechanism, cylinder and handle opening on one side
- Lock mechanism and cylinder opening without a handle opening
- Cylinder opening only
- Handle opening only
This flexibility allows manufacturers to configure the machine around different door and gate designs rather than relying on a single fixed punching sequence.
The PI85 can also create a production opportunity for businesses supplying pre-punched, ready-to-assemble tubing to other manufacturers, fabricators or door and gate producers.
Why Choose the Nargesa PI85?
The biggest advantage of the Nargesa PI85 is the amount of time it can save on repetitive lock preparation.
Preparing a tubular steel door or gate for lock installation manually can involve measuring, marking, drilling, cutting and filing multiple openings. The PI85 combines these operations into a dedicated production process that can complete the required preparation in approximately 58 seconds.
The machine is also designed around repeatability. Its dedicated tooling, internal tube support, integrated positioning stops and adjustable lock entrance help maintain consistent opening locations from one tube to the next.
The internal support core is especially important when punching thin-walled tubing, helping reduce the risk of deformation during the lock mechanism punching operation.
For manufacturers producing doors and gates in volume, the PI85 can help:
- Increase production throughput
- Reduce repetitive manual fabrication
- Minimize finishing and rework
- Improve consistency between parts
- Reduce assembly time
- Free skilled fabricators for higher-value work
- Create opportunities to supply pre-punched tubing to other manufacturers
The PI85 is purpose-built for a specific manufacturing problem: preparing square and rectangular steel tubing for lock installation quickly, accurately and repeatedly.

Frequently Asked Questions
What does the PI85 do?
It punches the lock case, handle and keyhole openings in a tube in one operation, a job Nargesa says normally takes an operator 30–45 minutes by hand.
What power does the PI85 need?
Nargesa specifies a 0.75 kW (1 HP) motor on a 230/400 V three-phase supply. Single-phase is available on request. Confirm your shop’s voltage with BTH Sales before ordering.
Which locks does it fit?
Nargesa says it fits 85% of locks of all brands and models with 85 mm centres and an 18–37 mm entrance.
Is the case length adjustable?
Yes. Both the case length and the lock entrance are adjustable.
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.
