Choosing a blade for the Bosch 4100
Start with compatibility, then choose for the material and cut you make most often.
Read the guide : Choosing a blade for the Bosch 4100Understand the documented limits and the required components before ordering a set.
Research-based guidance, with any historical owner observations identified. No new hands-on test results are claimed.

The linked original 4100/4100DG manual permits a stacked dado setup within its stated limits. That is a model-specific allowance, not permission to install any dado set that appears to fit.
The referenced manual sets a maximum dado diameter of 8 inches and a maximum width of 13/16 inch, and requires the Bosch TS1007 insert with the appropriate washer arrangement. Read the full instructions for configuration and operation; these headline limits are not installation steps.
Bosch describes the TS1007 as an insert for stacked dado and rabbet cutters and lists the 4000, 4100 and 4100XC in its compatibility information. The accessory includes a dado washer. Confirm the correct arrangement using both the saw and accessory documentation.
| Verify | Reason |
|---|---|
| Exact saw model | Avoid carrying specifications across similarly named versions. |
| Set dimensions and intended use | A product title is not a full specification. |
| Insert and required components | Account for the complete approved setup, not just the cutters. |
| The joint you need | Determine whether dado capability solves the actual project requirement. |
If you expect to make the same kind of joint repeatedly, the setup may earn its place. For a single project, compare equipment cost, setup time and the other suitable methods available in your shop. A feature you might use someday need not determine every purchase today.
No new joint-fit or cutting test is claimed here. This guide establishes the documentation to consult before choosing equipment. Start with model identification if your saw’s version is uncertain.
