The short answer: Yes, most modern jigsaw blades are universal. Since roughly 2005, the industry standardised on T-shank (also called Bosch-shank) which means a blade made by any brand fits any saw that accepts T-shank. You can buy Makita blades for a DeWalt saw, or vice versa, without compatibility concerns.
However, there are caveats: some older saws use U-shank (which is not interchangeable), and Ryobi has occasional fitment quirks. This page walks you through what to check.
T-Shank: The Universal Standard
The T-shank is the flat metal part at the base of the blade that inserts into the jigsaw’s chuck. It’s called “T-shank” because the profile vaguely resembles the letter T. All major brands now use it:
- Makita â T-shank only
- DeWalt â T-shank only (modern models)
- Milwaukee â T-shank only
- Bosch â T-shank only (creator of the standard)
- Ryobi â T-shank, with occasional fitment variations
If your saw was made after 2005, it almost certainly uses T-shank. This means you’re not locked into a brand â buy whatever blade is available, sharp, and good value.
U-Shank: Older Saws (Avoid If You Can)
U-shank (also called pin-shank or universal-shank) is older. The blade has two small pins at the base that slot into holes on the saw’s clamp. U-shank and T-shank are not interchangeable.
If you own a jigsaw from the 1990s or early 2000s, it might use U-shank. Check:
- Look at the blade clamp on your saw â does it have two visible holes?
- Try inserting a T-shank blade â if it doesn’t fit, you have U-shank
- Check your saw’s manual
If you have a U-shank saw, you’re limited to older blades. DeWalt and Milwaukee still make some U-shank blades for legacy tool users, but new U-shank production is dwindling.
Quick Compatibility Table
| Brand & Model Type | Shank Type | Universal? |
|---|---|---|
| Makita DJV series (cordless) | T-shank | Yes |
| DeWalt DCS331 (cordless) | T-shank | Yes |
| Milwaukee M18 JSA (cordless) | T-shank | Yes |
| Bosch PST (modern corded) | T-shank | Yes |
| Ryobi RJS1801 (cordless) | T-shank | Mostly yes (occasional fitment issues) |
| Older DeWalt, Makita (pre-2000) | U-shank | No â limited blade availability |
Why Does Ryobi Have Fitment Issues?
Most Ryobi jigsaws use T-shank, but the chuck design is slightly tighter than competitors’ models. Occasionally, a blade from another brand might be a very snug fit or require firm pressure to insert. This doesn’t mean it’s incompatible â it just means check the blade sits fully in the chuck before powering on.
If a blade won’t fit your Ryobi, try a different brand. Most Ryobi users have success with Bosch and DeWalt blades.
Frequently Asked Questions
Can I use a Bosch blade in my Makita jigsaw?
Yes. If both use T-shank (which they do), they’re completely interchangeable.
How do I know if my jigsaw is T-shank or U-shank?
Look at the blade clamp: T-shank saws have a slot (no holes), U-shank saws have two small holes for pins. Or try inserting a T-shank blade â if it fits, you have T-shank.
What if I own a U-shank jigsaw?
You’re limited to older blade supplies. Check with specialist tool suppliers â some still stock U-shank blades, but the range is small. Consider upgrading to a modern T-shank saw if you use the jigsaw frequently.
Can I use a jigsaw blade from any brand?
Yes, as long as your saw and blade both use T-shank. Brand doesn’t matter.
