My Buying Guides on ‘1 2 3 Blocks’

As a seasoned metalworker, I understand the importance of having reliable and accurate measuring tools. That’s why I highly recommend investing in a set of 1 2 3 blocks. These versatile and durable blocks are essential for any metalworking, machining, or engineering project. In this buying guide, I will walk you through everything you need to know about purchasing the perfect set of 1 2 3 blocks.

What Are 1 2 3 Blocks?

In case you are not familiar with them, let me give you a brief overview of what 1 2 3 blocks are. They are precision ground blocks made from hardened steel with dimensions of one inch by two inches by three inches. These blocks have threaded holes and through holes at various angles and distances from each other, making them incredibly versatile for different measuring and set-up tasks.

Things to Consider Before Buying

  • Purpose: The first thing to consider is what you will be using the blocks for. This will determine the size, material, and accuracy level that you need.
  • Material: The most common materials used for manufacturing 1 2 3 blocks are hardened steel and cast iron. Both have their advantages; steel is more durable and resistant to wear, while cast iron offers better stability.
  • Accuracy: Depending on your project requirements, you may need precision ground or machined blocks. Precision ground blocks have tighter tolerances and are more accurate than machined ones.
  • Holes: As mentioned earlier, the number and placement of threaded holes and through holes vary among different sets of 1 2 3 blocks. Consider your specific needs when choosing the block with the right hole configurations.

Different Types of Blocks

The market offers several types of 1 2 3 blocks that cater to different purposes. Here are some common types:

  • V-Blocks: These have V-shaped grooves on one side that can hold round objects securely for measuring or cutting tasks.
  • Cube Blocks: As the name suggests, these are square-shaped blocks with through holes on all sides for maximum versatility.
  • Precision Angle Blocks: These have precise angles machined on their sides for setting up or measuring specific angles accurately.

Budget

The price range for a set of quality-made basic steel or cast iron cubes is typically around $40-$50. However, if you require higher precision or specialized features like V-blocks or angle blocks, be prepared to spend more.

Tips for Maintaining Your Blocks

  • Clean your blocks after use to prevent rusting.
  • Avoid dropping them as they can damage the accuracy level.
  • If possible, store them in a protective case to prevent any damage or scratches.

I hope this buying guide has provided you with all the necessary information to make an informed decision when purchasing your set of high-quality and versatile 1-2-3 blocks. Happy shopping!
