- Oshlun SBW-100040 10-Inch 40T ATB General Purpose Blade
- Brand: Oshlun | Category: Saw Blades
The Oshlun 40T general purpose blade is a fairly standard ATB design with a steep positive hook, large C4 micrograin carbide teeth, thick steel plate, 0.125” kerf, and copper silencers. The fact that it’s available for ~ $25 is the most distinctive feature that separates it from other good quality 40T general purpose blades. It’s surprisingly well made, is very sharp, and performs well within the range capabilities of a blade of this design. It’ll rip glue ready edges in materials up to roughly 2”, depending on your saw and the material. It leaves acceptable crosscuts for most applications, and does a pretty respectable job in most plywood too. Having tried most of the high end 40T and 50T general purpose blades that can cost over $100, I don’t think the performance level of the Oshlun quite holds it’s own against the very best, but it’s not that far behind either, and soundly outperforms most other lower cost blades I’ve tried (Skil, Irwin Marathon, Oldham, Vermont American, Delta Sidekick). It does a “good” job in most tasks, and a “very good” job in some (IMHO). The only tasks it performs poorly in, a Forrest, Tenryu, or Ridge Carbide of similar design would also perform poorly in. If you need ultra fine crosscuts or need to rip 3” hard maple, a high quality dedicated specialty blade for those tasks is a better choice. The Oshlun essentially has similar strengths and weaknesses to the comparable top shelf blades….versatility and good performance in a wide range of tasks.
The fact that it’s $25 is secondary in my assessment of it’s performance. Most lower cost blades have less carbide, often only C2 hardness which doesn’t hold an edge as long, and/or sloppy brazing and overall construction. Most less expensive blades are also only available in a thin kerf. Some cheaper blades will cut well for a while, but many don’t cut all that well from the start,and I typically advice against cutting corners on a cheap blade. Note that the Oshlun isn’t available in a thin kerf in this configuration, but if a lower cost full kerf general purpose blade is on your radar, this one will be tough to beat IMO. (AFAIK, Oshlun was formerly the Avenger brand)
(Holbren has it for ~ $24.41 shipped with “SMC10”, “BT310”, or “woodnet10” discount code for members of those forums. Amazon, Rockler, and Eagle America/Price Cutter also carry them).
