Tolsen Ratchet Crimping Pliers 175mm (7-inch) - 38058

MPN: 38058

Barcode: 6933528738749

Size: 0.25-10mm²

Weight: 420g

Overview:

The Tolsen 175mm ratchet crimping pliers are built for fast, accurate wire crimping across a wide range of cable gauges. Covering 0.25 to 10mm² (AWG23-7), they suit everything from fine signal wiring to heavier electrical connectors. Whether you're wiring a consumer unit or working on automotive electrics, these pliers help you get consistent results.

A built-in star wheel lets you adjust crimping pressure to match the connector and cable size in use. This stops over-crimping and reduces the chance of damaged ferrules or poor connections. The ratchet mechanism releases automatically once the correct crimp force is reached.

The safety lock holds the handles closed when the tool is not in use. A quick-release trigger inside the handle opens the jaws instantly, cutting down on wasted time between crimps.

Key Features and Benefits

• Wide cable range: Handles wire gauges from 0.25 to 10mm² (AWG23-7), covering most domestic and light commercial wiring tasks.
• Self-adjusting ratchet: Automatically adapts to different wire gauges without manual adjustment between each crimp.
• Star wheel pressure control: Fine-tune crimping force to suit the connector type, preventing over-crimping and protecting ferrules.
• Automatic ratchet release: The ratchet disengages once the correct crimp force is applied, giving you a clean, consistent result every time.
• Quick-release trigger: A trigger inside the handle opens the jaws instantly, speeding up work when handling multiple terminations.
• Safety lock: Squeezing the handles engages the lock, keeping the pliers closed and compact when not in use.
• ABS handle: The handle material provides a firm, secure grip and reduces hand fatigue over prolonged use.
• Compact 175mm length: The 7-inch overall size makes these pliers easy to manoeuvre in tight spaces, such as within enclosures or cable trays.
• 420g weight: Light enough for prolonged use without unnecessary strain on the wrist or forearm.
• No over-crimping: The controlled ratchet action stops you applying excessive force, which is a common cause of connector failure.

Typical Applications

• Electrical installations: Crimping ferrules onto cables in consumer units, distribution boards, and junction boxes.
• Automotive wiring: Terminating wire ends on vehicles, caravans, and trailers.
• Data cabling: Fitting crimp connectors to low-voltage signal and data cables.
• Home wiring projects: Connecting cables to plugs, switches, and sockets in household settings.
• Panel building: Terminating control panel wiring with bootlace ferrules for a tidy, professional finish.
• Solar and low-voltage systems: Crimping terminals on battery, solar, and 12V wiring installations.

How to Use

• Prepare the cable: Strip the insulation from the wire end to expose the correct length of conductor, then insert it into the appropriate ferrule or crimp connector.

• Set the pressure: Rotate the star wheel to adjust the crimping pressure for your connector size and cable gauge before you begin.

• Position the connector: Place the ferrule or connector into the correct jaw slot that fits the wire gauge you are working with.

• Crimp the connection: Squeeze the handles steadily - the ratchet mechanism will advance with each squeeze and release automatically once the correct force has been reached.

• Release and inspect: Use the quick-release trigger if you need to open the jaws before the cycle is complete, then check that the crimp is secure and the conductor is not protruding from the connector.

• Store safely: Squeeze the handles together to engage the safety lock before placing the pliers in a tool bag or drawer.

Frequently Asked Questions (FAQs)

• What wire gauges do these crimping pliers work with?
  These pliers cover a range of 0.25 to 10mm² (AWG23-7), which takes in the majority of standard domestic and light commercial cable sizes.

• What is the purpose of the star wheel on ratchet crimping pliers?
  The star wheel adjusts the amount of force the jaws apply during the crimp cycle. Turning it lets you match the pressure to the specific connector and cable, which stops the ferrule from being crushed or deformed.

• Can I open the jaws mid-crimp if I make a mistake?
  Yes. A quick-release trigger inside the handle lets you open the jaws at any point during the cycle without completing the crimp.

• Are these pliers suitable for bootlace ferrules?
  Yes. The adjustable jaw and self-adjusting ratchet make them aptly suited to crimping bootlace ferrules commonly used in panel wiring and control cabinets.

• What does the safety lock do?
  Squeezing the handles activates the safety lock, which holds the jaws closed when the tool is not in use. It keeps the pliers compact and stops the jaws from opening accidentally in a tool bag.
