Can DeWalt Bits Fit a Milwaukee Drill? Yes, If Shanks Match
Yes — DeWalt drill bits work in a Milwaukee drill, because standard round-shank and 1/4-inch hex-shank bits are universal across every major brand. The chuck grips the shank, not the logo stamped on the bit. Where compatibility actually breaks down is proprietary systems: SDS-Plus/SDS-Max rotary hammer bits and specialty quick-connect holders like Festool Centrotec. The table below shows exactly which bit-and-chuck combinations are safe to mix.
Quick Answer
Yes. Any standard twist bit or 1/4″ hex bit fits any brand’s drill or impact driver, DeWalt included. The only real exceptions are proprietary shank systems (Festool Centrotec, older Bosch SDS-Quick) and mismatched SDS sizes — Plus and Max won’t interchange.
Chuck Type Determines Compatibility, Not Brand
The single biggest misconception about drill bit compatibility is that it’s a brand issue. It isn’t. A drill’s chuck is a mechanical clamp built to a specific shank diameter and shape — it has no way of “knowing” whether the bit inserted into it is DeWalt, Milwaukee, Makita, or Bosch. As long as the shank fits the chuck, the bit works. Here’s how that plays out across the shank types you’ll actually run into:
| Chuck / Shank Type | DeWalt ↔ Milwaukee Compatible? | Why |
|---|---|---|
| 3-jaw keyless chuck, round shank (3/8″ or 1/2″) | Yes | Chuck jaws grip any round shank of matching diameter — this is brand-agnostic by design |
| 1/4″ hex quick-change (impact drivers, impact-ready bits) | Yes | Industry-standard hex interface used by DeWalt, Milwaukee, Makita, Bosch, and Ryobi alike |
| SDS-Plus (rotary hammers) | Yes, within SDS-Plus | The SDS-Plus spec is a brand-independent mechanical standard — a DeWalt SDS-Plus bit locks into a Milwaukee SDS-Plus hammer drill |
| SDS-Max (larger rotary hammers) | Yes, within SDS-Max only | Not interchangeable with SDS-Plus — the shank diameter itself is different (roughly 18mm vs. 10mm) |
| Proprietary quick-connect (Festool Centrotec, older Bosch SDS-Quick) | No | Brand-specific shank geometry with no cross-brand fit |
The 1/4-inch hex shank is one of the most standardized bit interfaces in the power tool industry — used by every major cordless brand for both drill bits and impact driver bits, which is exactly why hex-shank sets get marketed as “universal.”
When Brand Actually Matters
Brand isn’t completely irrelevant — it just shows up in different places than most people expect. If you own a rotary hammer or SDS hammer drill, the SDS spec (not the brand) governs fit, but SDS-Plus and SDS-Max hardware are two different physical sizes that don’t interchange with each other regardless of brand. Specialty systems like Festool’s Centrotec chuck are deliberately proprietary and won’t accept any other manufacturer’s bits at all. And separately, cordless tool battery platforms are not interchangeable the way bits are — a DeWalt 20V MAX battery won’t power a Milwaukee M18 drill, even though the bits inside that drill’s chuck couldn’t care less which brand made them.
“SDS-Plus and SDS-Max are chuck standards, not brand standards — a bit from any manufacturer fits any rotary hammer built to the same SDS spec. The failure point is always shank type, never the logo on the tool.” — Tool Compatibility Hub, SDS-Plus vs. SDS-Max guide
Drill Bits vs. Driver/Impact Bits: Why People Mix This Up
Part of the confusion around “Dewalt bits in a Milwaukee drill” comes from lumping two different tool categories together. Twist bits (the kind used to bore holes for wood screws or pilot holes) almost always use a round shank sized for a standard 3-jaw chuck. Driver and impact bits — screwdriver tips, nut drivers, and impact-rated drill bits — use the 1/4″ hex quick-change format instead, built to survive the hammering rotational force an impact driver produces. Both formats are universal across brands; they’re just different standards for different jobs, which is why a DeWalt hex bit works in a Milwaukee impact driver just as easily as a DeWalt twist bit works in a Milwaukee drill.
How to Check Compatibility on Your Own Drill in Under a Minute
- Look at the chuck itself — most keyless chucks are stamped with their max capacity (typically 3/8″ or 1/2″) right on the collar.
- Measure the bit’s shank diameter with calipers, or check the size printed on the bit or its packaging.
- Confirm the shank shape: round (standard twist bits), 1/4″ hex (impact/quick-change bits), or SDS (rotary hammer bits).
- If it’s SDS, glance at the diameter: SDS-Plus is roughly 10mm and SDS-Max is roughly 18mm — they are not interchangeable even within the same brand.
- If your bit or chuck is a proprietary system (Festool Centrotec, some compact Bosch drills), check the manufacturer’s spec sheet before assuming cross-brand fit.
If you’re shopping for a new DeWalt drill specifically because you already own a set of Milwaukee bits (or vice versa), you can buy with confidence as long as you match chuck size and shank type using the checklist above. It’s also worth confirming which bit material and tip style suits the material you’re drilling, since that affects performance more than brand ever will.
Universal Bit Sets Worth Buying (Work With Any Brand Drill)
If you’re buying new bits specifically for cross-brand flexibility, here are three currently-available sets that match the compatibility rules above — one for each shank type covered in this guide.

1/4″ hex shank — the same universal fit in DeWalt, Makita, and Bosch impact drivers.
Check Price
Bosch 5-Pc. SDS-Plus Rotary Hammer Bits
SDS-Plus shank — fits any brand’s SDS-Plus rotary hammer, not just Bosch.
Check PriceFrequently Asked Questions
Can I use DeWalt drill bits with any drill?
Yes. Standard twist bits with round or 1/4″ hex shanks are universal — they fit any brand’s drill or impact driver as long as the shank diameter matches your chuck size.
Are drill bits interchangeable between brands?
Yes, for the vast majority of bits. Compatibility depends on shank type and diameter, not brand. The only real exceptions are proprietary systems like Festool Centrotec.
Will Milwaukee SDS or hammer-drill bits fit a DeWalt drill?
Only if both tools use the same SDS standard (Plus or Max). SDS is a brand-independent mechanical spec, so a Milwaukee SDS-Plus bit fits a DeWalt SDS-Plus hammer drill, but it will never fit an SDS-Max chuck.
What bit systems are NOT interchangeable between brands?
Proprietary quick-connect systems — most notably Festool’s Centrotec and older Bosch SDS-Quick attachments — use brand-specific geometry with no cross-brand fit. Mismatched SDS sizes (Plus vs. Max) also won’t interchange, regardless of brand.
Do impact driver bits need to match the drill brand?
No. The 1/4″ hex shank used by impact-ready bits is a universal standard across DeWalt, Milwaukee, Makita, Bosch, and Ryobi.
Conclusion
DeWalt drill bits fit a Milwaukee drill whenever the shank type and diameter match — that covers virtually every standard twist bit and hex-shank driver bit on the market. The exceptions are narrow and specific: mismatched SDS sizes and proprietary quick-connect systems like Festool Centrotec. Check your chuck’s stamped capacity, match the shank type, and you can mix DeWalt, Milwaukee, or any other reputable brand’s bits with confidence. For drills with special attachments, such as a 90-degree angle attachment, the same round-shank rule still applies — the attachment’s own chuck is what matters, not the drill body’s brand.
