Product Information

Full details

The Fisher Combination Square (FB225ME) is designed for carpenters, metalworkers, and fabricators who need a precise and versatile tool for layout tasks. Its key benefit is combining multiple essential functions – try square, mitre square, depth gauge, ruler, and more – into a single, durable instrument. A potential caveat is the need for careful handling to maintain the accuracy of the polished steel blade.

FAQs

What is a combination square used for?

A combination square is a multi-functional layout tool used for marking and measuring angles (90 and 45 degrees), checking squareness, measuring depth, and serving as a straight edge and rule in woodworking and metalworking.

How do I ensure accurate measurements with this tool?

Ensure the blade is securely locked, the stock is placed firmly against the edge of your material, and all surfaces are clean. Avoid applying excessive force that could flex the blade.

Can I use this tool for precise fine-tuning or only rough layouts?

The Fisher Combination Square is designed for precision layout. With careful use and proper locking, it can be used for accurate marking and measurement in detailed work.

What is the purpose of the centre head?

The centre head attachment is used to accurately find the center point of a round or square object. When the tool is slid over the material, the V-groove in the centre head, combined with the blade, will align with the exact center.

Is the blade reversible for marking on either side?

Yes, the blade has markings on both sides and can be used for measuring and marking from left to right or right to left, depending on your setup.

How often should I check the squareness of the tool?

It's good practice to check the tool's accuracy periodically, especially if it has been dropped or subjected to harsh use. A quick check against a known square or trusted straight edge will confirm its calibration.

What is the material of the blade and stock?

The blade is made of polished steel, and the stock is made of a matt black die-cast material for durability.

Troubleshooting

Blade slips or does not hold position

Ensure the brass locking screw is tightened sufficiently. Check the screw threads and the corresponding threads on the stock for any damage or debris. Clean threads if necessary.

Inaccurate readings (not square or plumb)

Verify the blade is fully seated and locked in the stock. Check for any nicks or burrs on the blade or stock edges. Ensure the work surface and the tool's stock are clean and free of debris.

Scriber is difficult to access or use

Ensure the scriber is properly seated in its holder. If it's stuck, try gently wiggling it while pulling. Keep the scriber tip clean and sharp.

Spirit level bubble is not centered at 0 or 90 degrees

The spirit level is factory set and not user-adjustable. Minor discrepancies may occur. For highly critical leveling tasks, use a dedicated spirit level. Ensure the blade is perfectly aligned with the stock when checking 90 degrees.

Pros and Cons

Pros

  • Versatile multi-tool reduces the need for several individual measuring instruments.
  • Clear, dual imperial/metric markings enhance readability in various applications.
  • Durable construction with a die-cast stock and polished steel blade.
  • Secure blade locking mechanism maintains accuracy.
  • Includes essential accessories like a spirit level and scriber.

Cons

  • Requires careful handling to prevent damage to the polished blade and maintain accuracy.
  • The spirit level might not be as precise as a dedicated level for critical applications.
  • Can be slightly heavier than simpler rulers or squares due to its multi-functional stock.

Setup, Compatibility & Care

Setup:

  1. Blade Adjustment: Loosen the brass locking screw on the stock.
  2. Position Blade: Slide the steel blade to the desired position, ensuring it moves smoothly but without excessive play.
  3. Secure Blade: Tighten the brass locking screw firmly to hold the blade in place. Do not overtighten, which could damage the screw or blade.
  4. Attach Centre Head (if needed): Slide the centre head onto the stock or blade as required for the specific task.

Compatibility:

This tool is designed for general woodworking, metalworking, and fabrication tasks. It is compatible with most common workshop materials including wood, metal, and plastics.

Care:

  • Cleaning: Wipe the blade and stock with a soft, dry cloth after each use to remove dust and debris. For stubborn marks, use a slightly damp cloth and dry immediately. Avoid harsh solvents.
  • Storage: Store the combination square in a dry place, preferably in its original packaging or a tool case, to protect the blade from scratches and rust.
  • Lubrication: Lightly oil the steel blade periodically, especially if stored for extended periods or in humid conditions, to prevent rust.
  • Calibration: Periodically check the accuracy of the square against a known straight edge or a certified square, especially if the tool has been dropped or subjected to impact.
