Like most professionals in construction, we rely on our tools across a range of projects and applications. So if you compare the cost per cut of an angle grinder against other metal cutting tools, it makes sense to use products that get the job done quicker or cheaper. Especially from a commercial and business perspective.
There are several tools to choose which can help you achieve performance, profit and productivity for metal cutting applications. These include band saws, recip saws, circular saws and more.
On-site, it’s common to grab a grinder or multi‑tool out of convenience or habit. But using the nearest tool can actually cost time and money compared to the correct cold‑cutting metal tools. Cold‑cutting tools offer several advantages:
No need for hot‑work permits, which are required for tools that generate heat or sparks.
Lower labour costs since you don’t need someone monitoring for fire risks.
Improved safety with fewer sparks, burns, or the need for flame‑retardant clothing.
No rework or re‑galvanising needed after cutting, especially when using tools that deliver clean, precise cuts.
Modern angle grinders include safety features, but other tools can still be safer. Using alternatives can reduce common risks:
Flying discs:
Grinder discs can break and cause serious injuries. Circular saws and band saws operate at lower RPMs and have guards that reduce this hazard.
Dust control:
Grinders rarely have dust ports due to their design. Alternatives like circular saws often include dust extraction, while aftermarket grinder attachments may not fit well or work effectively.
Vibration:
Grinders often have higher vibration levels (e.g., 5 m/s², limiting use to about 2 hours). Tools with lower vibration—such as band saws (0.8 m/s²) or circular saws (0.5 m/s²)—can perform the task faster and with less risk.
