Compak Bolt 83: an 83mm grinder that shifts between doser and on-demand service
The Compak Bolt 83 is a high-volume commercial espresso grinder with 83mm flat burrs and a distinctive workflow: it can operate with an internal dose reserve during a rush or switch to on-demand grinding when traffic slows. This gives a café the speed advantages of prepared dosing without giving up the control of freshly ground on-demand service.
The design is intended for busy bars where output changes sharply over the day. During peak periods the grinder can prepare the next programmed dose while the barista serves the current one; during quieter periods it can be used in a conventional doserless mode.

- Hands-free portafilter workflow
- Black finish

Performance and workflow
Large 83mm burrs provide the speed and thermal capacity expected in a production espresso grinder. The Bolt system is especially useful where peak throughput matters: the grinder can stage measured coffee for rapid service and then return to on-demand operation to limit unnecessary waste when volume drops.
Best use case
Choose the Bolt 83 for a busy café, bakery, drive-through, restaurant, or multi-barista operation with pronounced rush periods. It is less compelling for a quiet home setup, where the simpler E6 or i3 models are easier to justify.

How this Compak grinder compares
The Bolt 83 differs from the E8 OD LLS by adding a flexible internal dosing strategy for peak traffic. The E8 remains a conventional on-demand 83mm grinder. Choose the E10 for conical-burr flavor or the E6 for a smaller 64mm commercial platform.
