2677-20
6T driver kit with M18 battery/charger, 7/16" and 3/4" draw studs, 3/4" Rapid Reset draw-stud set, Quick Connect alignment system and carrying case. It is not the same thing as a complete 1/2"–2" punch/die kit.

Milwaukee Knockout Set Guide: 6T vs 10T, EXACT Dies & Draw Studs
“Milwaukee knockout set” can mean several different kits built around two M18 FORCE LOGIC drivers. The important choice is not just 6-ton vs 10-ton—it is the exact tool catalog number, punch/die range, draw-stud family, material capacity and whether an adapter is required.
Fastest selection rule
Choose the driver first, then verify the EXACT punch/die size and the matching draw stud. Treat competitive punches/dies as a separate adapter path—not as universal interchangeability.

Milwaukee 6T vs 10T knockout tools
| Platform | Core tool | Best fit | Manual capacity reference | Key compatibility point |
|---|---|---|---|---|
| M18 FORCE LOGIC 6T | 2677-20 | Service work, tighter spaces, lower tool weight | 6.7-ton peak output; manual lists 4" conduit holes in 14-ga mild steel and 2" conduit holes in 14-ga stainless steel | Quick Connect system; EXACT punches/dies; competitive accessories only through documented adapter/stud arrangements |
| M18 FORCE LOGIC 10T | 2676-20 | Higher-force commercial/industrial work and larger punch ranges | 10-ton peak output; manual chart lists 1/2"–4" EXACT sizes at 10-ga mild / 12-ga stainless, with 5"–6" at 12-ga mild / 14-ga stainless | Supports the broader EXACT system, larger draw studs and documented competitive-adapter paths |
Why we use the manual here.
Milwaukee’s current 6T product pages contain inconsistent gauge wording between the overview and bullet list. The current operator manual 58-14-2707D2 provides a specific capacity table for catalog 2677-20, so ElectricalTradeTools.com uses that manual as the controlling technical reference.
Current Milwaukee knockout kit families
Milwaukee sells the driver in different bundle configurations. A model number that looks almost identical can change whether punches/dies are included, so the catalog number matters when buying a set or replacing a case.
2677-21 / 2677-02 family
Current Milwaukee listings pair the 6T driver with the common 1/2"–2" EXACT conduit punch/die range. Verify the exact bundle contents before ordering because tool-only and punch/die configurations are both sold.
2676-20
10T driver kit with M18 batteries/charger, Quick Connect components and draw studs. Milwaukee’s current listing also includes its adapter for other major brands of punches and dies, but no full EXACT punch/die range is included in this base kit.
2676-22
10T kit built around the 1/2"–2" EXACT punch/die range, with 7/16" and 3/4" draw studs and the Quick Connect system.
2676-23
Expanded 10T kit that adds the larger EXACT punch/die range through 4" and the larger draw-stud path required for those sizes.
EXACT punch, die and draw-stud map
The current 10T operator manual publishes the catalog-number chain from conduit trade size to EXACT die, punch and regular draw stud. This table keeps the core 1/2"–4" range together so replacement parts can be checked by number rather than appearance.
| Conduit size | EXACT die | EXACT punch | Regular draw stud family |
|---|---|---|---|
| 1/2" | 49-16-2660S | 49-16-2661S | 7/16" · 49-16-2680 |
| 3/4" | 49-16-2662 | 49-16-2663 | 3/4" · 49-16-2681 |
| 1" | 49-16-2664 | 49-16-2665 | 3/4" · 49-16-2681 |
| 1-1/4" | 49-16-2666 | 49-16-2667 | 3/4" · 49-16-2681 |
| 1-1/2" | 49-16-2668 | 49-16-2669 | 3/4" · 49-16-2681 |
| 2" | 49-16-2670 | 49-16-2671 | 3/4" · 49-16-2681 |
| 2-1/2" | 49-16-2672 | 49-16-2673 | 1-1/8" · 49-16-2682 |
| 3" | 49-16-2674 | 49-16-2675 | 1-1/8" · 49-16-2682 |
| 3-1/2" | 49-16-2676 | 49-16-2677 | 1-1/8" · 49-16-2682 |
| 4" | 49-16-2678 | 49-16-2679 | 1-1/8" · 49-16-2682 |
Milwaukee also publishes Rapid Reset and long-draw-stud options for some larger sizes. Use the operator-manual accessory chart when replacing those variants.
Competitive punches and dies: adapter direction matters
49-16-2685 · Milwaukee power unit → other major brands
Milwaukee documents 49-16-2685 for using other major brands of punches and dies with its FORCE LOGIC knockout tools. The current 49-16-2685 product page explicitly lists 1/2"–2". The 6T and 10T operator manuals use broader “small and large” wording and instruct users to use the other brand’s draw studs and spacers as required.
49-16-2684 · competitor power unit → Milwaukee EXACT 2-1/2"–4"
Milwaukee’s service-parts/accessory documentation identifies 49-16-2684 as the EXACT adapter for competitor power units to Milwaukee EXACT 2-1/2"–4" dies. That direction is the opposite of 49-16-2685 and should not be used as evidence that a Milwaukee driver accepts large competitive punches.
Larger competitive punches on a Milwaukee driver
The current 49-16-2685 product page explicitly lists 1/2"–2", while Milwaukee operator manuals use broader “small and large” language. Until a current size-specific source resolves that mismatch, ElectricalTradeTools.com keeps the larger competitive-driver path unknown rather than extending the claim.
Which Milwaukee knockout set should you start with?
Start with the 6T family
If compactness and common service-size work dominate, the 6T platform is the natural Milwaukee family to evaluate first. Confirm stainless requirements against the manual because the stainless size limit is narrower than the maximum mild-steel size.
Start with the 10T family
If you need larger knockout sizes or higher material capacity, the 10T system provides the broader published range and the larger draw-stud/accessory path.
Check adapters before rebuying the system
If you already own another punch/die family, verify whether Milwaukee explicitly documents the required adapter path for your size range before replacing the whole set.
Compare current Milwaukee M18 knockout-tool listings
Choose 6T vs 10T and decide whether you need a driver-only system or a kit with EXACT punches/dies before comparing current listings. Verify the seller’s exact Milwaukee catalog number against this guide.
Need only the draw stud?
The Milwaukee Knockout Draw Stud Guide maps the documented 49-16-2680, 2681, 2682 and larger long-stud paths by punch size, including regular versus Rapid Reset distinctions.
Replacement parts: match the catalog number, not just the size
Milwaukee publishes service-parts lists for both the 2677-20 6T and 2676-20 10T tools. For hydraulic/electronic tool repairs, Milwaukee directs service through authorized repair channels. Punches, dies, draw studs, couplers and Quick Connect components should be matched to the exact tool and accessory chart.
For the punch/die side of the system, the table above is the safer starting point than searching for “Milwaukee 2-inch knockout die” and assuming every listing is the same component.

Milwaukee knockout set FAQs
What is the difference between the Milwaukee 6T and 10T knockout tools?
The M18 FORCE LOGIC 6T tool is the lighter service-oriented platform, while the 10T tool provides the higher-force and larger-capacity platform. The operator manuals should control the exact material and size limits for the specific catalog number.
Which Milwaukee knockout kit includes punches and dies?
Milwaukee sells tool-focused kits and punch/die kits. Current 2677-21 and 2676-22/2676-23 listings include specified EXACT punch/die ranges, while 2677-20 and 2676-20 are tool-system kits without a full punch/die range. Always check the exact catalog number.
Can Milwaukee knockout tools use other brands of punches and dies?
Yes in specific documented configurations. Milwaukee 49-16-2685 is the documented FORCE LOGIC-to-other-major-brand adapter; its current product page explicitly lists 1/2"–2", while operator manuals use broader small-and-large wording. Larger competitive-driver paths remain unknown here when the current documents do not agree. Adapter 49-16-2684 is a different direction: competitor power unit to Milwaukee EXACT 2-1/2"–4" dies.
What draw studs are used with Milwaukee EXACT knockout punches?
The current 10T manual maps 7/16", 3/4" and 1-1/8" draw-stud families by punch size. Larger sizes also have Rapid Reset and long-stud variants.
Are Milwaukee EXACT punches and dies rated for stainless steel?
Milwaukee documents EXACT punches/dies for both mild and stainless steel, but the allowable gauge depends on the tool and size. Use the operator-manual chart rather than assuming one rating applies to the entire family.
