Bosch OSL400F 4 in. Starlock® Oscillating Multi Tool Bi-Metal Segmented Saw Blade

Nice pack of blades. Name brand. Strong. Sharp. Good value

High Quality Worth the extra money for name brand

These are stupid expensive but they are worth it. Twice as fast as the old school straight blades and they seem to last a little longer too.

I use these everyday all day with my construction business and they hold up

A narrower version of this blade ships with the Bosch tools. This one is the widest blade Bosch makes at 2.5" inches. The slight curvature of the blade makes it easier to start cuts, control, and guide the blade. Bosch sells a similar blade, the OSL212JF. At first glance these two blades look similar but the main difference is in the style of teeth, as designated in the last digits of the model number. The Japanese tooth version of the blade (JF) cuts more aggressively in wood but you have to be careful not to hit any nails or metal. This version of the blade (F) does't cut as fast in wood but you can use it to cut through nails without a worry. It also leaves a cleaner cut in wood than the Japanese tooth version. The blade can plunge all the way through a 2x4, but just barely. The blade ideally should be at least a 1/4" longer, which would make it much more useful, and for that I've removed a star. If you're not familiar with Starlock blades, they're a quick-release mount blade primarily designed to be used on Starlock mount tools. However you can use these blades on most other non Starlock oscillating tools. Some tools may require an adapter which Bosch sells. If you buy an oscillating tool that has a Starlock mount please note you can only use Starlock blades, you will not be able to use your non Starlock blades on a Starlock tool. If you currently own a non Starlock oscillating tool and plan to buy a Starlock tool at some point in the future, then you might want to consider buying Starlock blades for your current tool, that way you will be able to use them later on when you buy a Starlock mount equipped tool.

Bosch generally makes good stuff, so I expected good performance when I bought these. I've had other Bosch blades in the past and have been very satisfied with them. I use a Harbor Freight oscillating tool (which I like) and on a day when I was feeling particularly cheap I bought a bunch of cheap Harbor Freight blades to use on a project. Yuk! The new Harbor Freight blades were dull by comparison with the Bosch ones, and they cut a jagged kerf twice as wide with double the effort. When I went back to Bosch, they seemed obviously sharper, cut with a kerf half as wide and involved significantly less effort per cut. You get what you pay for.

These things are expensive but man do they last. Remodeling a house and spent a good but of time yesterday cutting through ancient heart pine that's about as hard as a rock along with a ton of nails. Still on the first blade and hasn't shown any signs of slowing down. Usually I buy a Fien assortment pack that comes out to around $5 a blade but they were out of stock so these were the next best quality blade at a decent price. It appears these hold up better than the Fien when cutting nails. Also the slight curve in the blade makes plunge cuts super easy. These are not cheap by any means but way better than buying a single blade locally for $20 a pop.

Great price for Bosch blades
