INTBUYING T028371FBA, 12 V mini mill-drill review

A 12-volt mini drilling and milling machine with a belt drive and no plastic in the body — and a listing that publishes not one dimension or speed.

Where we come out The same class of 12-volt mini mill as its better-documented twin on this shelf, on a page that publishes a voltage and nothing else.

This is a 12-volt bench mill-drill of the model-engineering class, and almost everything that can be said about it comes from three sentences of construction: a 12 V DC transformer drives it, the body has no plastic parts, a belt carries the drive, and a clamping vice is built into the base.

Those are real points. A belt between motor and spindle slips when a cutter jams, which on a small machine with no stated overload protection is the thing that saves the motor; an all-metal body is stiffer than a cast plastic one; and a vice built in rather than bolted on is one less thing to align. The listing also tells you to slow down on harder material and to wear goggles, which is more than some machines here manage.

What it does not publish is any number at all beyond the voltage. No power rating, no spindle speed, no axis travel, no vice capacity, no collet range, no handle resolution and no runout. The JARYANNIX machine on this shelf, at ten dollars more, publishes every one of those — and its reference, FT-028371, shares the digits 028371 with this listing’s T028371FBA. What that means about who made either is not something either page says.

What it handles, and what it will not

Strengths

  • A belt drive rather than direct drive, which is quieter and protects the motor from a jam
  • An all-metal body with no plastic parts, stated
  • An integrated clamping vice at the base
  • Runs from a 12 V DC transformer, which is as safe as a bench machine gets
  • Warns that harder material needs a slower speed, and that goggles are needed

Compromises

  • Publishes no dimension, no travel, no speed and no power rating anywhere
  • Its reference, T028371FBA, shares the stem 028371 with the JARYANNIX mill on this shelf, which publishes a full parameter table
  • Four bullets, one of which is a safety note and one a description of what a belt does
  • No runout figure, no collet range and no vice capacity

The questions welders ask

How does it compare with the JARYANNIX mill?

The two listings describe the same kind of machine and only one of them tells you anything. JARYANNIX publishes a full table: 24 W, a 3,000 rpm spindle, a spindle jump under 0.1 mm (0.004 in), X travel of 45 mm (1.77 in), Y and Z of 35 mm (1.38 in), a 50 by 60 mm (2.36 in) vice, collets from 1 to 6 mm (0.04 to 0.24 in) and a 0.05 mm (0.002 in) handle scale. This listing publishes a voltage and three sentences about construction. Their references share the digits 028371.

Is a belt drive worth having on a machine this size?

Yes, for one reason the listing gives and one it does not. The stated reasons are smoothness, low noise and easy maintenance. The unstated one matters more: a belt slips when the cutter jams, where a direct-drive motor stalls and heats. On a 12 V machine with no overload protection mentioned, that slip is the protection.
