Grinders & Polishers, Electrolytic Polisher & Etcher
QETCH 100 M
The Qetch 100 M is a mobile battery supplied electrolytic polisher and etcher.
Lot # and price held 7 days after order.
NDA standard
Ships in 1–2 business days
Spec-match guarantee on every lot
Built for production teams
What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.
A materials engineer on the line
Questions on ferrite content, flowability, recyclate ratios, or HIP response? A materials engineer answers directly — not a contact-form bot. Most replies in under 4 hours, NDA standard.

POLISHING UNIT
The polishing head is integrated in the handle. Polishing and etching gets automatically ready by touching the piezo button in the handle. A multi-coloured LED on the handle indicates all program states. The operator can focus his attention completely to the checkpoint. The handle is connected to the unit by a flexible hose. For flat surfaces, the exchangeable sealing-lip ring is especially suitable. Complex surfaces (e.g. angled areas) can be examined by using an additional flexible end piece which can be cut to size individually. The pump’s adjustable performance allows an infinitely variable flow rate regulation of electrolyte
CONTROL PANEL
The LC-display clearly shows all important parameters like current, voltage, time as well as the charge of battery. All parameters can be adjusted via control panel during operation. You can choose between constant current and constant voltage.
BATTERY SUPPLIED OPERATION
The high capacity lithium battery allows with a single charge approximately 150 simple etching/polishing cycles including pre-grinding (state of charge display, charging and mains operation via external power
supply). Up to 30 examinations are possible by using the mobile grinder at the same time.
INNOVATIVE DETAILS
Micro motor, straight handle and accessories of our mobile grinder Qpol 30 can optionally be connected directly to the controlling unit of the Qetch 100 M (suitable storage area inside the case). The electrolyte tanks are replaceable and with screwed top for external storage. The integrated return-flow filter optimizes the life time of the electrolyte.
SAFETY FUNCTIONS
An additional locking valve allows the flow of the electrolyte only
during the cycle.

Unedited feedback from customers who reorder QETCH 100 M.
★★★★★
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
