The winning team<br />
for deep-hole drilling<br />
Mikron Tool drilling concept<br />
90°<br />
Step 1<br />
CrazyDrill Pilot<br />
Step 2a<br />
Step 1<br />
Inclined pilot hole with<br />
CrazyDrill Crosspilot<br />
Drill guided<br />
in pilot hole<br />
Step 2b<br />
Drilling of deep holes<br />
without noticeable<br />
diameter differenze<br />
between pilot hole<br />
and bore<br />
Step 2<br />
Drilling of inclined holes<br />
with CrazyDrill <strong>Cool</strong><br />
The advantage<br />
The drilling concept from Mikron Tool is specially designed<br />
for deep holes and is based on a two-stage principle.<br />
With CrazyDrill Pilot or CrazyDrill Crosspilot centering and<br />
pilot hole is carried out in one step. The CrazyDrill <strong>Cool</strong> then<br />
reaches the maximum depth with minimum pecking. This<br />
combination enables direct drilling with an inclination angle<br />
of up to 60° and guarantees optimum guidance of the<br />
subsequent drill with a negligibly small diameter difference.<br />
This drilling concept can be used as a substitute for deep<br />
hole drilling down to a depth of max. 15 x Ø in the<br />
diameter range 0.75 – 6 mm. Without investing in expensive<br />
manufacturing systems and finish reaming operations a<br />
greater productivity is achieved.<br />
Characteristics<br />
• Solid Carbide alloy<br />
• Coated or uncoated<br />
• Standard lengths up to 15 x Ø<br />
• Special lengths and special executions upon request<br />
Five benefits<br />
• Maximum drilling speeds and feeds<br />
• Minimal run out<br />
• Increased tool life thanks to pilot drilling<br />
• Can replace deep-hole drilling<br />
• Suitable for difficult to machine materials
