My Buying Guide on 6 Inch Combination Square
When I first started working on woodworking and metal projects, I quickly realized how essential a good 6 inch combination square is. It’s one of those versatile tools that every craftsman should have in their toolbox. Over time, I’ve learned what to look for to make sure I’m getting the best value and functionality. Here’s my guide to help you choose the right 6 inch combination square for your needs.
Understanding What a 6 Inch Combination Square Is
A 6 inch combination square is a multi-purpose measuring tool used primarily for marking and checking 90° and 45° angles, measuring depths, and even drawing straight lines. The “6 inch” refers to the length of the ruler blade, which is perfect for most small to medium projects.
Why I Prefer a 6 Inch Size
I find the 6 inch blade length to be the sweet spot – not too short that it limits measurement, and not too long to be cumbersome. It’s compact enough to carry around easily and fits well in my tool bag, but still versatile enough for most tasks I encounter.
Key Features I Look For
- Blade Material: I prefer stainless steel blades because they resist rust and maintain accuracy over time.
- Locking Mechanism: A solid, easy-to-use locking screw is a must. It keeps the blade firmly in place while I work.
- Precision and Markings: Clear, laser-etched markings are important for accuracy and longevity. Faded or painted markings can wear off quickly.
- Built-in Level: Some combination squares come with a small bubble level. I find this feature handy for quick leveling tasks.
- Adjustable Head: The ability to slide and lock the head anywhere on the blade adds a lot of flexibility.
Material and Build Quality Matter
When I first bought a combination square, I underestimated the importance of build quality. Cheaper models often have plastic parts or flimsy components that wear out or break quickly. I recommend investing in a tool with a solid metal head and a sturdy blade. It makes a big difference in durability and precision.
Additional Accessories and Features
Some combination squares come with extra features like:
- A scriber (a small pointed tool) stored in the head for marking.
- Conversion scales (metric and imperial) on the blade.
- A magnetic base for metalworking.
I personally find the scriber and dual scale very useful, especially when switching between different measurement systems.
Price vs. Quality: What I’ve Learned
While it’s tempting to go for the cheapest option, I’ve found that spending a bit more upfront on a quality combination square pays off in the long run. It stays accurate, lasts longer, and makes my work easier and more precise.
Where I Usually Buy Mine
I typically shop at reputable hardware stores or online marketplaces where I can read customer reviews. Brands like Starrett, Swanson, and Empire have consistently delivered reliable tools for me.
Final Tips from My Experience
- Always check for a good warranty or satisfaction guarantee.
- Handle the tool before buying if possible to see how it feels in your hand.
- Keep it clean and store it properly to extend its lifespan.
Choosing the right 6 inch combination square has made a noticeable difference in my projects. I hope these insights help you pick the perfect one for your toolbox!
