Unlike standard manual magnetic drills, the E5000 Auto's autonomous drilling capability allows a single operator to run multiple machines concurrently, reducing labor overhead on repetitive hole-cutting tasks. The DrillSmart technology actively manages feed rate and motor load to extend both cutter and machine life, while the LiftShield system adds an additional layer of operator protection not found on conventional mag drills.
Key Features & Benefits
Fully Automatic Drilling (Auto Feed)
The E5000 Auto can be set to drill and shut down completely autonomously — once the capstan lever is engaged, the spindle plunges, completes the cut, retracts, and powers off without operator input. This allows one operator to oversee multiple machines simultaneously, significantly increasing throughput on repetitive drilling operations.
DrillSmart Technology
DrillSmart is Unibor's integrated feed-rate management system that optimizes cutting performance to maximize both machine and cutter service life. By preventing overloading during the cut, it reduces the risk of cutter breakage and costly downtime on the job site.
LiftShield
LiftShield provides an additional safety layer by monitoring magnet adhesion conditions during operation. For contractors working overhead or on vertical surfaces, this feature adds critical protection against unexpected machine release.
2-Speed Gearbox with Variable Speed Control
The two-speed gearbox (Gear 1: 100–2468 RPM; Gear 2: 200–5000 RPM) combined with variable speed control allows the E5000 Auto to be optimized for both large-diameter annular cutters at lower speeds and smaller-diameter or carbide cutters at higher speeds. Selecting the correct speed for the cutter diameter reduces heat buildup and extends cutter life.
Multi-Function Capability: Drilling, Countersinking, Twist Drilling & Tapping
Beyond core cutting, the E5000 Auto supports twist drilling up to 3/4", countersinking up to 1-3/16", and tapping up to 3/4" — eliminating the need to swap machines between operations. This versatility makes it a single-tool solution for structural steel and fabrication workflows.
3034 lb Magnetic Adhesion Force
The high-force electromagnet (rated at 3000 lbs at 20°C with a minimum 1" plate thickness) provides a secure, stable platform even on vertical and overhead surfaces. A stable base is essential for accurate hole placement and prevents cutter breakage caused by machine movement during the cut.
LED Work Light & Internal Cabling
The integrated LED work light illuminates the cutting zone for accurate positioning in low-light environments. Internal cabling routing eliminates exposed wiring that could snag on workpieces or structural members, reducing trip hazards and cable damage on busy job sites.
Quick Release Interchangeable Handle
The quick-release handle design allows rapid repositioning or removal to suit confined-space access requirements without tools. This is particularly useful in structural steel and fabrication environments where clearance around the drill is limited.
CSA Approved
The E5000 Auto carries CSA certification, confirming it meets recognized North American electrical and safety standards. For contractors working on regulated job sites, CSA approval simplifies compliance with site safety requirements.
Common Applications
Structural Steel Fabrication
The E5000 Auto is designed for drilling ferrous metal in fabrication shops, where its auto-feed function enables high-volume, repeatable hole production with minimal operator fatigue.
Construction & Site Work
On construction sites, the drill's powerful magnet and portable form factor allow it to be positioned on beams, columns, and plates in any orientation — including vertical and overhead — for in-place structural drilling.
Railway Infrastructure
The manual identifies railway applications as a primary intended use, where precise, clean holes in heavy ferrous rail components are required and machine stability is critical.
Petrochemical & Industrial Facilities
In petrochemical environments, the drill's ability to mount securely to pipe and structural steel — including with the optional pipe adapter kit — makes it suitable for maintenance and installation drilling on process equipment and pipework.
Multi-Machine Operations
The autonomous auto-feed function is specifically designed to allow one operator to run multiple E5000 Auto units simultaneously, making it well-suited to production drilling tasks where throughput is the priority.

Application Instructions
Setup & Mounting
- Ensure the magnet is switched OFF before plugging the machine into the power supply.
- Clean the underside of the magnet base — it must be flat, clean, and dry before mounting.
- Position the machine on the workpiece and switch on the magnet to secure it.
- Attach the safety strap (RDC4083) and stationary rings (RDC4082) to a fixed independent feature before operating. Affix stationary rings into the uppermost side hole of the magnet to reduce potential free movement if the magnet becomes detached.
Cutter Installation
- Disconnect the machine from the power source before changing cutters.
- With the machine upright, ensure the Arbor Assembly (CA120) is fully inserted into the Arbor Spindle (RDC4009).
- Place the appropriate pilot through the hole in the cutter shank. Insert the cutter shank into the bore of the Arbor Assembly, aligning the two drive flats with the socket screws.
- Tighten both screws securely using the hexagon key before operating.
Gear & Speed Selection
- Select the appropriate gear using the slide selector: Slide Up or Slide Down as indicated on the machine.
- Set the electronic speed controller to the correct speed for the cutter diameter BEFORE starting the machine. If the speed controller is adjusted after starting, the auto-feed function will not perform correctly.
- Refer to the Cutting Speed Selection chart (page 24 of the manual) for recommended speeds by cutter diameter.
Manual Drilling Operation
- Ensure the coolant bottle contains sufficient cutting oil for the operation. Use only approved cutting fluid — do not use water-diluted cutting oil.
- Start the machine following the control panel operation instructions.
- Apply light pressure when commencing the cut until the cutter is introduced into the work surface, then increase pressure sufficiently to load the motor. Do not apply excessive pressure — it does not increase penetration speed and will trigger the safety overload protection.
- Keep the inside of the cutter clear of swarf, as swarf buildup restricts operating depth.
- Always switch off the motor using the MOTOR STOP button. Do NOT switch off the motor using the MAGNET switch.
- Ensure the slug has been ejected from the previous hole before commencing the next cut.
Auto Feed Operation
- Turn on the mag drill and confirm it is set to the correct speed for the cutter being used.
- With the unit running, push the capstan lever towards the machine to activate the auto-feed. The spindle will begin to plunge automatically.
- Once the drilling operation is complete, the spindle will automatically retract until the cutter is clear of the workpiece and the machine will shut off.
- If the spindle does not retract completely, deactivate auto-feed by pulling the capstan levers to the manual position, manually retract the cutter, then turn the drill off.
- Note: The auto-feed function is optimized for low-to-medium carbon steels and supports core cutting up to 2" x 2" and twist drilling (1/2"–1" only).
Chuck Fitting
- Insert RDC4087 (Arbor Shank) into RDC4009 (Arbor Spindle) and ensure a tight fit.
- Insert RDC4084 (1/2" Chuck) into RDC4087 and ensure a tight fit.
- To remove the chuck, reverse the sequence using RDC4086 (Drift).
Pipe Adapter Kit Fitting
- Depending on the pipe diameter, attach adjustable angle plates (RD3328) with cap screws (RD4325) and washers (RD4205, 4 off each) to the magnet sides. Do not fully tighten at this stage.
- Locate the machine on the centerline of the pipe, ensuring the magnet is aligned with the longitudinal axis of the pipe.
- Switch on the magnet and move the sliding plates down to the outside diameter of the pipe. Tighten the screws on both sides by hand, then verify the full length of the moving plates contacts the pipe at front and back. Fasten the plates securely.
- Feed the safety strap through the lugs at the front of the housing, around the pipe, and pull tight.
- When cutting, do not use excessive pressure — allow the cutter to ease into the cutting surface.
