How To Master The Kobalt Glass Cutter

Glass cutting can be a daunting task, but with the right tools and techniques, it can be a breeze. Here's how to use a Kobalt glass cutter step by step.

Step 1: Clean The Glass Surface

Start by ensuring that the glass surface is clean and debris-free.

Use a soft cloth to wipe the surface clean. Any debris or dirt can cause the glass cutter to slip, resulting in an uneven cut.

Lightly brush kerosene onto the section you intend to cut. This not only prepares the glass but also aids in the cutting process.

Step 2: Dip The Cutter In Kerosene

Dip the Kobalt glass cutter in kerosene before use. This will lubricate the cutter and make cutting through the glass surface easier.

Make sure to wipe off any excess kerosene before use.

Step 3: Hold The Cutter at 90°

With a firm grip, position the Kobalt glass cutter at a 90° angle to the glass. Consistent pressure is key; score the glass in one fluid motion.

It's essential to avoid stopping midway or retracing over an already-scored path.

Step 4: Bend The Glass

After you've achieved a clear score on the glass, it's time to separate the pieces.

Hold the glass on either side of the score using your thumb and forefinger, then apply a slight bending pressure.

The glass should snap cleanly along the scored line. Always wear gloves during this step to shield your hands from potential sharp edges.

Step 5: Finishing Up

Once you have successfully cut the glass, use fine-grit sandpaper to smooth out any rough edges.

Be sure to clean the glass surface again before use.

Replacing The Kobalt Glass Cutter Blade

If you notice that your Kobalt glass cutter blade is dull or damaged, it's time to replace it.

Follow these simple steps to replace the blade and keep your glass cutter working effectively.

Step 1: Release The Screw

First, locate the screw at the end of the glass cutter handle. To release the handle, slightly turn the screw counterclockwise - about half a circle.

Be cautious not to unscrew too much; otherwise, you risk dislodging other parts.

Step 2: Replace The Blade

To switch to a new blade, locate the nut securing the blade. Rotate the nut counterclockwise and remove it from the glass cutter.

It's crucial to ensure that the washer beneath the blade remains securely in place, preventing any hindrance to the cutting edge.

Step 3: Reattach The Screw

After ensuring the blade is set correctly, rotate the nut back to its original position.

Finish the process by turning the screw clockwise to firmly secure the handle onto the cutter.

Safety Measures When Using The Kobalt Glass Cutter

When working with glass, safety should always be your top priority.

Here are some safety measures to keep in mind when using the Kobalt Glass Cutter:

  1. Always wear thick, non-slip gloves to protect your hands from potential cuts and provide a firm grip on the tool and glass.
  2. Shield your eyes from any glass splinters or shards that may fly off during cutting.
  3. Ensure you're working on a flat, stable surface to prevent the glass from moving unexpectedly.
  4. Keeping your workspace free of debris or unnecessary items minimizes the chance of accidents or mistakes.
  5. Always hold the Kobalt Glass Cutter firmly to avoid slipping during cutting.
  6. Apply consistent and even pressure when scoring to reduce the risk of the glass breaking unpredictably.
  7. Keep any unused glass pieces in a safe place to avoid accidental injuries.
  8. Always keep a first aid kit nearby. In the event of minor cuts or injuries, you'll want immediate access to first aid supplies.

If you're looking for a reliable glass cutter that won't break the bank, the Kobalt Glass Cutter is definitely worth considering.

With a comfortable, double-injected TPR handle and six alloy steel cutting wheels, this cutter is designed to make cutting glass a breeze.

While it may not be suitable for cutting mirrors or tempered glass, the Kobalt Glass Cutter can handle thicknesses from 1/8 inch to 1/5 inch.
