Our Review
The JMD 30-piece T118A set delivers solid value for metal-cutting applications on a budget. The 75mm length and 21TPI configuration handles mild steel, aluminum, and sheet metal efficiently, with aggressive teeth that resist premature dulling. However, blade quality varies within the pack—some cut cleanly while others show inconsistent tooth geometry that requires slower feed rates. For intermittent home workshop use, this set eliminates frequent blade purchases, but professional job site demands will expose durability limitations within 50-100 cuts on harder materials. The high tooth count (21TPI) excels at finish cuts but struggles on thicker stock above 3mm.
What We Like
- 30-blade count provides excellent value and reduces reordering frequency for hobbyists
- 21TPI tooth pitch produces clean edge finishes on aluminum and thin steel
- Standard T-shank compatibility works with most modern jigsaw models
Watch Out For
- Inconsistent blade quality across the set leads to variable cutting performance
- Teeth dull relatively quickly on ferrous metals compared to premium brands
- Limited effectiveness on material over 4mm thickness due to aggressive tooth design
The Verdict
“A practical budget option for occasional metal cutting in home workshops, but professional users should expect blade replacement costs to offset initial savings.”
