K&M Offers New Variable Speed Case Prep Center
When it comes to reloading hardware, some guys have to have the best of the best, regardless of cost. For those guys, K&M Precision has introduced an impressive new variable-speed, multi-station case prep center. This is quite a step up from other variable-speed case prep devices.*
K&M offers two versions, one with a single spindle (tool driver) running 50-200 rpm, and another modular design that can have up to six (6) spindles, running from 50 to 533 rpm. This Ferrari of case prep centers costs $2395.00 with all six spindles, with lesser prices for fewer spindles (e.g. $1795 with three spindles). The basic 50-200 rpm one-spindle machine costs $695.00. That’s still a pretty sizable investment. But for some guys, price is no object.
Watch Video to see six-spindle machine in action. Being able to adjust the speed within a broad rpm range really is a big deal. You can go slow when needed, then instantly bump up the rpm when you need to do other tasks at a higher rate. Cutting vs. brushing work best at different speeds.
The K&M Benchtop Case Prep Machine is an industrial-grade unit that features an industrial DC brushless motor for constant torque control over a speed range from 50 to 533 rpm (or 50-200 rpm for basic model). The speed can be quickly changed by simply rotating the dial switch and pressing to enter the speed. Watch the video to see the speed control in action. Models are available from one- to six-spindle configurations. The driven spindles feature a unique collet design that accepts ¼” hex shank tools that are oriented horizontally for natural ergonomics. Collet and idler spindles ride on oil-impregnated bronze bearings for smooth operation. You can use K&M-made tools or drive other types of tools using a ¼” hex tool shank adapter with either 8-32 or 3/8-24 threads. Each model has a spring-loaded spindle lock pin to hold the spindle position while setting tools or loading/unloading cartridges into the power adapter.
All machines come with quality hard case with foam, chip pan, chip brush, 1/4” hex drive adapter for 8-32 and 1/4” hex drive adapter for 3/8-24.

RCBS had a variable speed machine at the Shot Show last year.
Editor: Read the footnote to our article. We explained that RCBS has a multi-speed case prep center, introduced last year. Four heads run at max 350 rpm, while two heads run at max 550 rpm. RCBS also previously had a Universal case prep center, which includes a trimmer. This has six stations available for case preparation, four turning at 360 RPM (max) and two turning faster at 550 RPM (max). The RPM is variable.
For the price vs value, I’m keeping my RCBS. It’s worked well for over 15 years.

The RCBS brass boss is a variable speed unit controlled by a variable speed rheostat. There are two high speed stations that max out at 550 RPM and 4 that max at 350 RPM. They will run extremely slow by adjusting the rheostat hinting variable speed.
RCBS also released their Universal Case Prep Center about six years ago which utilizes the same variable speed rheostat to give the unit variable speeds.
