Short answer

FoxAlien, Carbide 3D and Genmitsu treat the DeWalt DWP611 as a 69 mm router, and Genmitsu and FoxAlien sell 69 mm holders for named machines. Sienci calls its DWP611 mount 71 mm, and neither side explains the difference, so buy the holder whose maker names both your router and your machine.

Key facts

Nominal bore
69 mm (about 2.72 in, calculated from 25.4 mm per inch)[1][2]A calculation, not a tolerance.
Labels makers use
69 mm for the DeWalt DWP611 class (FoxAlien, Carbide 3D, Genmitsu); Sienci lists its 71 mm LongMill mount for the DWP611[1][3][4][5]Both labels are shown; we do not average or resolve them.
Routers and spindles made to it
DeWalt DWP611 class (FoxAlien's 69 mm Z clamp, Genmitsu's ZC69 example, Carbide 3D's 69 mm Sweepy 2.0 for the DeWalt trim router)[1][4][3]
Machines with a holder in this size
Genmitsu 4040-PRO, 4040-PRO MAX, 4040 Reno, 3020-PRO Ultra and 3030-PROVer MAX (101-63-ZC69); Genmitsu PROVerXL 4030 V2 and 4x4 Z (101-63-4030V2-ZC69); FoxAlien Masuter Pro (sold separately), Masuter 3, 4040-XE, XE-PRO, WM3020, Vasto and CL-4x4 (Z clamp; not the XE-Ultra). Carbide 3D announced a 69 mm DeWalt mount in May 2021 for the Shapeoko Pro, Shapeoko 4 and HDZ (V4.0).[4][6][1][7][8]The Carbide 3D mount is a historical announcement, not current availability.
Rings and shims to other sizes
PwnCNC reducing shim 69 to 65 mm, 25 or 75 mm high[9]Designed mainly around PwnCNC mounts, per PwnCNC.
Collet systems makers pair with it
The DeWalt DWP611's own extended 8-slot 1/4 in collet[10]DeWalt's page gives only 27,000 rpm, not a full speed range.
Dust boots for this size
Carbide 3D Sweepy 2.0 69 mm (DeWalt trim router); Genmitsu DS69 (65-69 mm, 32 mm inner and 38 mm outer port)[3][11]
How to check yours
Measure the body's outside diameter with a caliper on the band the mount clamps, and the mount's inside diameter. PwnCNC advises measuring mount ID, usable clamp height and body OD before ordering a shim.[9]Plain technique; we give no tolerance.
Not confirmed
Why the DWP611 is labeled 69 mm by some makers and 71 mm by Sienci; neither source explains it[5][1]

Watch out for

  • The same DeWalt DWP611 is a 69 mm router to FoxAlien, Carbide 3D and Genmitsu and a 71 mm router to Sienci. Do not mix one maker's label with another maker's mount.
  • FoxAlien's standard 69 mm Z clamp does not fit the XE-Ultra; FoxAlien sells a separate XE-Ultra clamp.
  • Carbide 3D's 69 mm DeWalt mount is a May 2021 announcement; it is not evidence of current stock.
  • Genmitsu's 4040-PRO family ZC69 and its 4030 V2 ZC69 are different holders for different machines.

What fits

Questions

Is the DeWalt DWP611 69 mm or 71 mm?

Both labels are in use: FoxAlien and Carbide 3D call their DWP611 parts 69 mm, while Sienci lists its 71 mm LongMill mount for the DWP611. Neither explains the difference, so buy the mount whose maker names the DWP611 and your machine.[1][3][5]

Can I run a 65 mm router in a 69 mm mount?

PwnCNC sells a 69 to 65 mm reducing shim in 25 and 75 mm heights, designed mainly around its own mounts. Measure the mount and body before ordering.[9]

Which dust boots come in 69 mm?

Carbide 3D sells Sweepy 2.0 with a 69 mm collar for the DeWalt trim router, and Genmitsu matches its DS69 to 65-69 mm spindles.[3][11]
