The winning team
for deep-hole drilling
Mikron Tool drilling concept

Step 1
CrazyDrill Pilot
Step 2a
Step 1
Inclined pilot hole with
CrazyDrill Crosspilot
Drill guided
in pilot hole
Step 2b
Drilling of deep holes
without noticeable
diameter differenze
between pilot hole
and bore
Step 2
Drilling of inclined holes
with CrazyDrill Cool
The advantage
The drilling concept from Mikron Tool is specially designed
for deep holes and is based on a two-stage principle.
With CrazyDrill Pilot or CrazyDrill Crosspilot centering and
pilot hole is carried out in one step. The CrazyDrill Cool then
reaches the maximum depth with minimum pecking. This
combination enables direct drilling with an inclination angle
of up to 60° and guarantees optimum guidance of the
subsequent drill with a negligibly small diameter difference.
This drilling concept can be used as a substitute for deep
hole drilling down to a depth of max. 15 x Ø in the
diameter range 0.75 – 6 mm. Without investing in expensive
manufacturing systems and finish reaming operations a
greater productivity is achieved.
Characteristics
• Solid Carbide alloy
• Coated or uncoated
• Standard lengths up to 15 x Ø
• Special lengths and special executions upon request
Five benefits
• Maximum drilling speeds and feeds
• Minimal run out
• Increased tool life thanks to pilot drilling
• Can replace deep-hole drilling
• Suitable for difficult to machine materials

Feed f in mm/revolution in relation to diameter (indicative)
This data is indicative. Different conditions due to machine, spindle, coolant, etc. can influence the performance. In case of
difficult conditions the feed rates should be reduced up to 30%.
In the case of drill diameters be low 1.0 mm and depths over 4 x d, Mikron Tool recommeds centering or a pilot hole. It
can be drilled using the CrazyDrill Pilot.
Important criteria:
For best results, Mikron Tool recommends the use of cutting oil as lubricant. The use of water based coolant with high pressure
additives, or minimum quantity lubrication is also possible as an alternative. In this case, the cutting parameters have to be
adjusted accordingly.

Recommendations for
optimum results
Cooling lubricant
Type
For optimum results Mikron Tool recommends the use of
cutting oil as a coolant. Alternatively emulsion can also
be used (with EP additives).
Filter quality
A good filter quality is particularly important for small
diameters:
• Filter quality of 10 microns for diameters < 1 mm
• Filter quality of 20 microns for diameters range
