CrazyDrill Twicenter
even centering can be cool

Short machining time

With CrazyDrill Twicenter, the drill with through-tool cooling, centering and chamfering take place in one step
Higher cutting speeds possible than with commercially available centering tools because of perfect cooling and tip geometry

Secure centering due to strong tip angle:
- The 130° tip angle allows free chip flow directly into the flute
- Together with the reduced chisel edge decreases the pressure on the tip
Optimal cooling and lubrication by means of through-coolant supply even in difficult-to-access spots
Due to through-tool cooling these drill bits for metal perform reliably even in difficult-to-machine materials such as stainless steels, titanium and super alloys

High degree of roundness and alignment accuracy
High position accuracy because of a sturdy design
High degree of precision for follow-up drilling because of centering and chamfering in one step, CrazyDrill Twicenter is therefore the ideal partner for long drills (every type of drill bits of the CrazyLine)

Longest tool life due to through-tool cooling and high-performance coating
Shorter machining time: Centering and chamfering in one step, high cutting speeds
High degree of process reliability due to optimal tip geometry
CrazyDrill Twicenter can be reground: this means lower tool costs

All CrazyDrill Twicenter are solide carbide drill bits for centering and suitable for the preparation of holes in various diameters and for various wide chamfers
Suitable for types of drills from the CrazyDrill series with a 130° tip angle such as CrazyDrill SST-Inox, or a 140° angle such as CrazyDrill Cool and others
Because of through-tool cooling it is especially recommended for drilling in stainless steel
Diameter range 0.3 mm – 6 mm (.0118" – .236") (center), 1 mm – 10 mm (.0393" – .394") (chamfer)
Three versions for different chamfers:
- 60° chamfer and good stability because of "double" tip (130° tip angle)
- 90° chamfer and good stability because of "double" tip (130° tip angle);
- 120° chamfer with the same tip angle (120°)

Centering tool made of tungsten carbide
Drill with through-tool cooling for simultaneous centering and chamfering
High process reliability due to strong tip angle
Longer tool life due to through-tool cooling and high-performance coating
Every CrazyDrill Twicenter center drill is suitable for various drill bits sizes
Recommended for machines with and without through-tool cooling (for example small CNC milling machines, different types of drilling machines or rotary transfer machines)
Can be reground and recoated; the drilling performance of a re-sharpened CrazyDrill Twicenter is equal to a new drill in terms of performance, precision and hole quality
Mikron Tool produces all types of drill bits with the highest degree of repeat accuracy. The user therefore has the benefit of long-term stability in production (reliability and precision of machining)
