In brief: Choosing the right metalworking tool depends on the material thickness, the level of precision you need and the scope of the job. For precise cuts in thin metal, fine-tooth reciprocating saw blades such as PRODUCT_73818 are ideal. For rougher work and faster cuts, coarser blades such as PRODUCT_73737 are a good choice. For electronics work, a powerful soldering iron such as PRODUCT_108145 is the way to go. Our comparison highlights the strengths of each type.
Metalworking demands the right tools and skills. Whether you are tackling a DIY project or doing precision work, the right equipment is key to success. Our 2026 test and comparison focuses on essential tools for cutting and joining metal.

Which saw blades are suitable for metal?
Only blades made specifically for metal are suitable. Wood saw blades would quickly become dull. The material and the blade's tooth pattern are key.
Bi-metal saw blades are the standard choice for demanding metalwork. They have a flexible spring-steel body and hardened teeth made from high-speed steel. This combination makes them durable and resistant to breakage.
The tooth count is measured in TPI (Teeth Per Inch). A high TPI count, such as 18, means more fine teeth per inch. This produces clean, slower cuts in thin material. A low TPI count, such as 10, means fewer, coarser teeth. They cut faster and more aggressively, making them ideal for thicker profiles.
Note: Tooth shape matters. “Milled and side-set” teeth offer the greatest precision. “Wavy-set” teeth help prevent binding when cutting softer metals.
Reciprocating saw blades tested
We took a closer look at two popular bi-metal reciprocating saw blades. Both are available in a convenient 5-pack.
: For fast, powerful cuts
The bi-metal reciprocating saw blade with 10-14 TPI and a tooth pitch of 1,8-2,5 mm is an all-around blade for thicker metals. It is ideal for pipes, profiles and solid material several millimetres thick.
The coarser teeth clear chips more effectively, so the blade is less likely to clog. You get faster cuts, though the cut edge may be slightly rougher. This blade is ideal for demolition, dismantling and other rough work.
: For precise cuts in thin material
With a fine tooth count of 18 TPI and a tooth pitch of just 1,4 mm, this blade is designed for thin sheet metal and precision work. It cuts material up to around 2-3 mm thick cleanly, with minimal burring.
Its main advantage is the smooth cut edge, which often means less deburring afterward. This blade is a great choice when accuracy and a clean finish matter, such as in model making or when working on car body panels.
How do the bi-metal blades compare in practice?
How do they differ in real-world use? Imagine you need to dismantle an old bicycle.
For the thick steel tubing of the frame, a coarse blade is the better choice. Its robust teeth cut aggressively and clear chips efficiently, helping you get through the material faster.
If you then need to cut through a thin aluminum sheet, a fine blade comes into its own. It cuts through the soft metal cleanly instead of tearing it. The risk of the sheet becoming distorted or frayed is much lower.
Tip: Keep both blade types on hand. Use the coarse blade for fast dismantling and the fine blade for accurate cuts. That way, you will be ready for any metalworking project.
Soldering instead of welding
Not every metal joint needs to be welded. For many jobs, soldering is a clean, simpler alternative, especially in electronics and when working with thin sheet metal.
With soft soldering, you join metals using a tin alloy that melts at a lower temperature than the base material. You need a soldering iron to heat the solder and the joint.
A soldering iron's wattage determines how quickly it reaches operating temperature and how well it maintains that temperature under load. 15-25 watts are enough for small solder joints. For larger surfaces or thick cables, you need extra power in reserve.
Soldering irons compared
There is a wide range of soldering irons available. We focus on a model that offers a good balance of performance and ease of use.
: A versatile all-around choice
The 40Watt ECO soldering iron provides a solid foundation for most hobby and DIY projects. Its 40 watts deliver a fast heat-up time and enough power for more demanding solder joints.
A key advantage of this set is its selection of tips. With the standard tip and two additional tips with a diameter of 4,9 mm, you can work on both delicate electronic components and heavier cable connections. This flexibility makes it a reliable tool for a wide range of jobs.
Important: Soldering irons get extremely hot! Always use a stable stand. Never touch the front third of the iron. Let it cool completely after use before putting it away.
Metalworking Buying Guide
Choose a tool based on the job you need to do. Ask yourself these questions:
- What material and thickness will you be working with most? For thick metal, choose coarse teeth (low TPI). For thin sheet metal, choose fine teeth (high TPI).
- How important is cut quality? A sturdy all-around tool is enough for rough demolition work. For precise cuts, invest in a quality blade with fine teeth.
- Are you soldering electronics or larger connections? A 25W soldering iron is enough for circuit boards. For cables and sheet metal, choose 40 watts or more.
- How often will you use the tool? Occasional users can get by with an entry-level set. If you use a tool regularly, durable, high-quality products are worth the investment.
Remember to get the right accessories, too. When sawing, you may need cutting oil. For soldering, a holder, desoldering braid, and cleaning sponge are essential.
Safety First
Metalworking comes with risks, so always use the right protection.
- Wear safety glasses to protect yourself from flying chips and sparks.
- For noisy tasks, such as sawing with a reciprocating saw, hearing protection is recommended.
- Work gloves protect against sharp edges and heat, but use caution: they can be hazardous around rotating machinery.
- Make sure your work area is well lit and free of tripping hazards.
- Wear the right protective clothing for each tool and make sure the workpiece is securely clamped.

Frequently Asked Questions
- Which reciprocating saw blade should I use for metal?
- For metal, you need bi-metal saw blades with specially designed teeth. The key factor is the number of teeth per inch (TPI). For thin sheet metal (up to 2 mm), choose 18 TPI or more for clean cuts. For thicker material (from 3 mm), 10-14 TPI is a better choice because it removes chips more effectively and is less likely to clog.
- What’s the difference between milled and wavy-set teeth?
- Milled and side-set teeth are more precise and leave a smoother cut edge, making them ideal when you want a clean, nearly finished result. Wavy-set teeth are more robust and less likely to clog when cutting softer metals or mixed materials, making them a good choice for demolition work. Choose based on whether cut quality or speed matters more to you.
- How many watts should a soldering iron have for electronics?
- For delicate electronics work on circuit boards, 15-25 watts is often enough. For thicker cables or larger solder joints, 40 watts or more is recommended. Stable temperature control is crucial. An iron such as PRODUCT_108145 offers the flexibility to handle different tasks, with 40 watts and interchangeable tips.
- Can I use a regular drill bit for metal?
- No. For metal, you need special drill bits made from high-speed steel (HSS) or carbide. They’re harder and have a specially shaped point. Always use cutting oil to reduce heat, make drilling easier, and significantly extend the drill bit’s service life.
- How do I maintain my metalworking tools?
- Remove metal chips and dirt from your tools after each use. Clean off any corrosion right away. Store saws and drill bits in a dry, protected place. Apply a light corrosion inhibitor before long-term storage. Have dull tools professionally sharpened or replace them to ensure clean results and stay safe.
