CrazyDrill Pilot
Centering and pilot hole drilling
in one step
Shorter machining time
- Short drill and chamfer tool for centering, pilot drilling and chamfering in one passage but not a DIN centering hole since the pilot hole has no additional protective chamfer
- High machining speed
Long tool life
- Optimal coating protects tungsten carbide drill from wear
- Sturdy design with reinforced shaft
- Longer tool life for the follow-up drill since it is guided in the pilot hole with the same tip angle and there is no risk of cutting edge breakage
High process reliability -
high productivtiy
- Degressive flute prevents catching at the transition to the chamfer and allows constant cutting conditions
- Cylindrical guidance of the follow-up drilling prevents drifting
- Simultaneous chamfering with 90° angle replaces countersink drill bit
- No jamming of the follow-up drill due to diameter tolerances perfectly matched to all Mikron Tool deep-hole twist drill types such as CrazyDrill Cool and CrazyDrill Cool XL
High degree of precision
- High degree of position accuracy and straightness due to sturdy design
- Highest degree of precision and straightness in deep holes longer than 6 x d since the pilot drill creates a guide bore, thus guiding the follow-up drill ideally.
- No measurable transition from pilot hole size to follow-up deep hole size
Lower production costs
- Center drill/pilot drilling up to 2 x d and chamfer of 90° in one work cycle
- Short machining time
- Long tool life and reliability of the follow-up drill through adapted tolerances and tip angles
- CrazyDrill Pilot can be reground. With this tool costs are being reduced
Coordinated and complete drilling program
- Pilot drill CrazyDrill Pilot with adapted diameter tolerance for subsequent twist drill types such as CrazyDrill Cool and CrazyDrill Cool XL (140° tip angle)
- Diameter range: drill sizes 0.4 mm – 6.35 mm (.016” to .250”, fractional inches available)
- Diameter increments: up to diameters of 4 mm (.016”) every 0.05 mm (.002”), from diameter of 4 mm (.016”) and up every 0.1 mm (.004”)
- Drilling depth: up to 2 x d
Special characteristics
- Center drill, pilot hole drilling and chamfering possible in one processing step
- High degree of precision for the follow-up drilling, no deviation in deep holes
- Longer tool life for follow-up drills because of adapted tolerance and tip angle
- Pilot drill with 90° chamfer for simultaneous chamfering
- Reinforced shaft diameter
- Degressive flute for good cutting and higher degree of reliability when chamfering
- Diameter measurement/increments matched to CrazyDrill twist drill types
- Can be reground and re-coated; drilling performance of a re-sharpened CrazyDrill Pilot is equal to a new drill in terms of performance, precision and hole quality
- Mikron Tool produces all tools with highest repeat precision. Hence the user will benefit from long term stable production conditions (stable process and machining precision)
