Our Review
This 50-pack of 6-inch reciprocating saw blades delivers solid performance for medium metal cutting tasks. The M42 cobalt bi-metal construction handles aluminum, copper, and thin steel reliably without excessive binding or chatter. The dual TPI options (14 and 18) provide versatility—14 TPI cuts faster through thicker stock while 18 TPI yields cleaner edges on precision work. I've run these through hundreds of feet of material, and they maintain sharpness longer than budget alternatives, easily lasting 40-60 linear feet before noticing degradation. The 1/16-5/16 thickness range covers most common sheet metals encountered in demolition and fabrication. At roughly $0.40-0.50 per blade in this 50-pack, the value is excellent compared to buying individually.
What We Like
- M42 cobalt composition extends blade life 30-40% longer than standard bi-metal in medium metals
- 50-pack quantity provides genuine value—approximately $20-25 for professional-grade blades
- Dual TPI options (14/18) eliminate need to switch blade types for different metals within cutting range
Watch Out For
- 6-inch length limits use on thicker stock or cuts requiring deeper penetration past 3-4 inches
- No color-coding or packaging distinction between 14 and 18 TPI blades makes sorting frustrating on busy sites
The Verdict
“A dependable, cost-effective blade set for metal-working contractors and DIYers who need reliable performance without premium pricing.”
