The inherent qualities of
ELORA ratchets are also very
impressive. The fine-toothed
precision-made gearing that
ensures concentricity and
maximum functionality.
The individual production
steps leading up to the
“marriage” of outer body
and inner mechanisms all
require extensive know-how
coupled with
an enthusiastic
attention to detail.

1. Blanking
The starting material is high-grade ELORA chrome vanadium
31 CrV3 / 1.2208.
2. Hot forging & flash removal
a. The cropped blank is heated in a furnace to the correct forging
temperature and then drop forged in this hot state using high
press forces. 03
b. Following this, the flash is then removed using flash-removal
presses.
3. Grinding & vibro-deburring
The subsequent grinding process ensures the tool has a smooth
outside surface. Any sharp edges and flash still remaining are then
removed by vibro-deburring.
4. CNC machining
The internal shaping of the ratchet head is machined exactly to
size in a machining centre.
5. Hardening and tempering
This special heat treatment ensures the longest possible service
lifetimes. The tool’s tensile strength is provided by precise
hardening to a given temperature and the high level of ductility by
the tempering process.
6. Sand blasting
To make sure the ratchet has a matt, non-slip
surface, we sand-blast it.
7. Electroplating
The surface is given durable anti-
corrosion protection and a
high-quality satin-finish
appearance.
8. “Marriage” & final
assembly
This process involves
bringing together the body
and internal mechanisms.
The handle, internal
mechanisms and cover are
fitted. The tool’s functionality
is thoroughly checked.
