HSS twist drill set with centring pin in storage case 6-piece set
Ø 1.5 – 2 – 2.5 – 3 – 3.5 - 4.. For precision tapping of wood and
plastics; also non-ferrous metal, steel and stainless steel sheets.
Titanium coating reduces friction and increases service life.
Shaft Ø 3, 6-piece set.
Note:
All measures are in mm.
Note:
The term HSS for this tool category
comes from the utilised drill material.
High speed steel (HSS) is a high alloy
tool steel extremely resistant to wear
due to its manufacturing process and
is dimensionally stable up to approx.
600°C.
Cutting oil or coolant emulsion should
be used as cooling lubricant, when
machining steel. Spirits or petroleum
should be used for aluminium.
Normally, plastic and wood can be
dry-machined.
lity
blank. The precise flutes and optimal concentricity ensure best life expectancy. Ideal for free-hand precision work. For use on hard and soft woods, non-ferrous and pre-
powerful fitting of the milling bits we recommend the use of MICROMOT steel collets as described above. See bottom left.
millers
stant highly compressed fine-granular tungsten carbide. Used for vibration-free milling of high accuracy dimensions. It is advisable to
well, avoiding accidents. For milling steel, cast steel, non-ferrous metals, plastics and extremely hard materials. May be used for technical
and milling of PC cards. Shafts Ø 3 or 2.35. Here also we recommend the use of MICROMOT steel collets.
Rasp cutter
For cutting and milling tiles,
stoneware, wood and plastics.
Tungsten milling cutters, 3 pieces
Two flute cutters and a fishtail profile ensure cutting to
the centre, allowing boring. Usable on grey cast iron,
hardened cast iron, steel, cast steel, brass, aluminium,
glass and even plastics and carbon fibre. One each of 1 –
2 and 3mm. 3mm shaft diameter. Can also be ordered
separately (see above).
NO 27 116
For all MICROMOT devices designed
for use with chuck. Advantageous
when working with different
shafts. Capacity 0.3 - 3.2.

Three-jaw steel
drill chuck
Drill chuck or collet?
Drill chucks provide more convenience to
quickly change the tools when working
with shafts of varying diameters (e.g. HSS
drills as per DIN 338). However, because
of their technical setup, they have a few
drawbacks compared to collets: Less
clamping force and higher concentricity
tolerances. If high precision is necessary,
then working with MICROMOT steel
collets is a must. See also note at left.
HSS twist drill in storage case 10-piece set. Similar to
DIN 338 Ø 0.3 – 0.5 – 0.8 – 1 – 1.2 – 1.5 – 2 – 2.5 – 3 – 3.2.
For drilling non-ferrous metal, steel and stainless steel.
In labelled cassette with fold back and stand function.
For clamping we recommend our 3-jaw drill chuck (see
below).
