Honey Badger Trimmer Adapter


SKU: N/A Category:



Designed specifically for the Bosch 1617 EVS router.  We do not know what other routers it may work on.

We don’t believe in cutting corners.  We wanted THE baddest case trimmer out there for any press, whether single stage or progressive.  What we came up with was the Honey Badger Trimmer Adapter.  Production pieces are CNC’d (non-CNC prototype pictured) from 12L14 steel to exacting tolerances.

Our adapter facilitates the mating of the Bosch 1617EVS Wood Router Plunge Cut Motor to any of the major trim dies from Dillon, CH4D, Whidden, or GSI to name a few.

Why the Bosch?  We liked a number of features.

  • 2.25 Horsepower; This motor can NOT be bogged down by too fast of a feed rate.
  • Soft start technology; This motor can be held by hand and turned on at wide open throttle without so much as a twitch.
  • Variable speeds; 8,000 to 25,000 RPM allows for precise, fast cutting.  Time is money!
  • RPM monitored; As load increases during cutting, so does power output.  The trimmer does what it needs to in order to keep a constant RPM.
  • Air cooling; The Bosch has it’s own built in cooling fan that puts out copious amounts of air.  Even after hours of use, the trimmer barely gets over room temperature.

What will you need to complete this beast?

  1. The Honey Badger Trimmer Adapter (of course! $90-$132.50)
  2. The Bosch 1617EVS Variable Speed Router Kit (Amazon has it at ~$175.00 with Prime)
  3. The Bosch 2610906287 3/8″ Collet Chuck for the above trimmer. (Again, Amazon, ~$20.00 with Prime)
  4. The Trim Die of your choice!  (Dillon, CH4D, Whidden, or GSI are known to work)
  5. Dillon Vacuum Shroud p/n 12996 for the RT1200/1500 Trimmer (About $25.00+ship)
  6. A 2 or 3 Flute, 3/8″, 2.5″ Long, Carbide End Mill (Check Ebay, can be had for around $20.00)

Total:  $330-378 + your favorite trim die (not included by the competition with their trimmer either).


So what’s up with the goofy looking nut?  Here’s the deal.  Threads wear as you screw them together and apart.  The wear will be more prevalent on the weaker of the two threads based on their material.  The competition’s trimmer is made from an aluminum base while all of the dies are made from steel.  With screwing and unscrewing dies from the competition’s trimmer, the threads wear unevenly, and eventually the cut starts to drift from perpendicular to the centerline of the case.  To easily see this, simply stand two cases on their trimmed necks and rotate the cases 90 degrees at a time.  If the gap between the cases grows or shrinks, the cases are not cut perfectly straight.

To make you drool a bit more, here’s a video link to the Honey Badger in action, rough cutting some .300 Blackout.


Proper Installation:

  1. Screw jacknut onto die.
  2. Screw adapter onto die.
  3. Setup proper trim length.
  4. Lock jacknut finger tight against adapter and mark a line down the adapter, jacknut, and die with a Sharpie marker (color insignificant).
  5. Take assembly to machine shop.
  6. Chuck die with adapter assembly into lathe.
  7. Back off jacknut one full revolution from locked against the bottom of the adapter, keeping lines marked in step 4 straight.
  8. Setup dial indicator against surface that mates with Bosch router motor.
  9. Use set screws in jacknut to set concentricity to desired accuracy.

Using this method, it is best to keep the adpater and die mated until the die wears out.


Simple Installation:

Use a 13/16-20 jam nut (not included) to secure die to trimmer adapter.

Using this method, the trimmer adapter can be easily moved from one die to another, although cutting concentricity will not be as accurate.


Instead of the Carbide End Mill, we offer a boring bar and carbide insert that we have tested and found works best.
