Table Saw — What a small table saw should NOT cut
cut target
This guide lists metals and conditions that are unsafe or unsuitable for small table saws. It also gives safer tool alternatives for cutting various metals.
1) Steel family — HIGH RISK (Do NOT cut)
- Carbon steel
- Alloy steel
- Stainless steel
- Spring steel
- Tool steel
Why not:
- Small table saws run at high RPM (typically 4,000–6,000 RPM) with no coolant
- The blade can overheat instantly and suffer tooth breakage
- Severe kickback and dangerous projectiles
Conclusion: Strictly prohibited
2) Thick metal (Any material) — NOT SUITABLE / HIGH RISK
- Aluminum sheet ≥ 3–4 mm
- Copper sheet ≥ 2 mm
- Brass sheet ≥ 2 mm
- Large metal profiles (angle, channel, etc.)
Why not:
- Excessive feed resistance
- Small table saws lack torque for heavy cuts
- Blade pinching and flying debris are likely
Conclusion: Avoid; use appropriate metal-cutting equipment
3) Hard, brittle metals — DANGEROUS (Do NOT cut)
- Cast iron
- Zinc alloys / die-cast parts
- Magnesium alloys
Why not:
- Parts can shatter or chip
- High-speed fragments pose major risk
Conclusion: Strictly prohibited
4) Thin-walled metal tubes and thin metal sheets — VERY DANGEROUS
- Tubes with wall thickness < 1 mm
- Thin steel/aluminum sheets
Why not:
- Teeth can grab and pull thin-walled parts
- Risk of entanglement, winding, and ejection
Conclusion: Extremely hazardous with a small table saw
May be cut only under strict, controlled conditions
These are conditional cases where cutting is physically possible but not recommended unless all precautions are met.
Prerequisites:
- Use a metal-specific blade (TCT blade for aluminum or a non-ferrous metal blade)
- Secure the workpiece firmly with proper clamps or fixtures
- Use very low feed and controlled cutting parameters
- Operator must be experienced with metal cutting on small machines
Possible (still not recommended):
- Non-ferrous thin parts only:
- Aluminum ≤ 2 mm
- Brass ≤ 1.5 mm
- Copper ≤ 1 mm
Note: "Can be cut" ≠ "should be cut" — safety and tool life remain major concerns.
Recommended tools by metal
| Metal / Part | Recommended tool |
|---|---|
| Steel / Stainless | Metal bandsaw / cold-cut saw / angle grinder with cutoff wheel |
| Large aluminum profiles | Cold-cut saw / dedicated sawing machine |
| Thin aluminum sheet | Jigsaw with metal cutting blades or shearing/cold saw |
| Small metal rods / bars | Metal bandsaw / hacksaw (manual) |
Micro-size table saw
Small benchtop saws can be useful for wood, plastics, and light hobby work — not for cutting most metals.
Full-size table saw
Full-size, industrial saws with appropriate blades, guards, and coolant systems may handle some non-ferrous metals safely when used with correct blades and feeding methods. Even then, choose a purpose-built metal-cutting machine whenever possible.
