What is a Circular Saw

Using a Circular Saw Blade for Metalworking

The Workhorse of Cutting: The Circular Saw

The circular saw is a versatile power tool with a spinning disc blade to tackle various cutting tasks. Initially designed for lumber, this electric saw comes in handheld and mounted varieties. The right blade can conquer multiple materials, including metal and plastic. Circular saws offer impressive performance at a budget-friendly price, making them popular compared to pricier options like wet saws and angle grinders.

Circular saws provide users with high performance

Cutting metal with a circular saw presents a unique challenge compared to wood. Unlike wood, where the blade removes large chips, metal cutting is closer to abrasion, generating a shower of hot, sharp metal shards. A full face shield and gloves are essential to tackle metal with this tool to minimize injury risk.

Gearing Up and Getting Started: Cutting Metal with a Circular Saw

Before diving in, prioritize safety! Wear a full face shield, gloves, and long sleeves to shield yourself from flying hot metal shards.

1. Sharpen Your Approach.

  • Blade Selection: Choose the right metal-cutting blade for your project. This ensures efficient and clean cuts.
  • Clamp It Down: Secure the metal firmly with clamps. Ideally, let it overhang the edge of the saw blade for better control.
  • Guide the Way: Mark your cutting line for a precise finish.

2. Cutting with Confidence.

  • Power Up and Align: Align the saw blade with your marked line, then slowly power on the saw.
  • Steady Does It: Carefully guide the saw into the metal, maintaining control throughout the cut.
  • Cooling Down: Regularly apply cutting fluid to reduce heat and friction, promoting a cleaner cut.

Remember: A circular saw is suitable for limited metalwork. Consider using a dedicated metal cutting tool, such as a metal chop or reciprocating saw, for thicker metals or frequent cutting.

HSS vs. TCT: Choosing the Right Blade for Metal

The type of metal you’re cutting is key to selecting the ideal circular saw blade. Here’s a breakdown of the two leading contenders:

1. High-Speed Steel (HSS).

These blades are budget-friendly for softer metals like aluminum and thin steel sheets. They offer good initial sharpness but wear down faster and aren’t suited for more rigid materials.

2. Tungsten Carbide Tipped (TCT).

TCT blades are the go-to choice for tackling tougher metals. They boast tough tungsten carbide tips fused onto a steel body. This translates to exceptional durability, allowing them to conquer a wider range of metals, including thicker steel and even some stainless steel.

Making the Right Call

For most metal-cutting jobs, a TCT blade is recommended due to its superior lifespan and ability to handle various materials. However, if you’re working with fragile, soft metals like aluminum and cost is a primary concern, an HSS blade might be a suitable option.

Pro Tip: Check your project requirements and choose the appropriate blade type. While we can’t directly promote specific brands here, a reputable manufacturer like Kinkelder offers various TCT saw blades capable of cutting through solid steel, bars, and tubes. Explore their selection to find the perfect blade for your metalworking needs!
