MiquDrill Solid Carbide Center Drill

Product Overview

Whether for centering, short-hole drilling, or precision drilling, Mikron Tool offers three types of industrial micro drills within the MiquDrill series, covering every application where small to medium batch production or high-variant manufacturing is required.

The MiquDrill drilling program is dedicated to small diameters. All sizes are available from stock, in both uncoated and coated versions.

Key advantage: diameters are offered in fine increments of 0.01 mm (0.0004"), ensuring maximum flexibility and precision in tool selection.


CrazyDrill Twicenter Solid Carbide Center Drill

Product Overview

The CrazyDrill Twicenter from Mikron Tool is a unique solid carbide center drill offering dual advantages. Equipped with through-tool coolant supply, it is specifically designed for centering operations in difficult-to-machine materials.

Traditional center drills tend to wear rapidly due to excessive heat accumulation. Thanks to internal coolant delivery, the CrazyDrill Twicenter maintains consistently low cutting temperatures while simultaneously lubricating the drill tip.

Even in challenging drilling positions — such as areas with protruding edges — the through-tool coolant system demonstrates its benefits, ensuring that the coolant medium always reaches the correct location.

The CrazyDrill Twicenter can also be successfully used with external coolant supply, guaranteeing the highest positional accuracy under all conditions.


MiquDrill Solid Carbide Short Drill / Pilot Drill

Product Overview

Whether for centering, short-hole drilling, or precision drilling, Mikron Tool offers three types of industrial micro drills within the MiquDrill series, covering every application where small to medium batch production or high-variant manufacturing is required.

The MiquDrill drilling program is dedicated to small diameters. All sizes are available from stock, in both uncoated and coated versions.

Key advantage: diameters increase in fine increments of 0.01 mm (0.0004"), ensuring maximum flexibility and precision in tool selection.


CrazyDrill Flex Solid Carbide Short Drill / Pilot Drill

Product Overview

The CrazyDrill Flex from Mikron Tool enables drilling in diameters from 0.10 mm to 2.00 mm (0.004" to 0.079", fractional inch sizes available), with dedicated versions for steel, titanium, and stainless steel (including a coated version for steel and fractional inch sizes for stainless steel).

A direct connection element (neck) between the cutting body and the shank provides the solid carbide CrazyDrill Flex with the required length for deep-hole drilling up to 50 × D, while ensuring exceptional rigidity.

With CrazyDrill Flex, small and deep holes can be drilled quickly, precisely, and cost-effectively on machining centers, automatic lathes, or rotary transfer machines — eliminating the need for gun drilling machines.

Although the flexible solid carbide (VHM) drill is not specifically designed for plastics, it can also be applied to certain thermoplastics and acrylic glass (PMMA).

Three drill types are available:

  • CrazyDrill Flex Steel

  • CrazyDrill Flex Titanium

  • CrazyDrill Flex SST-Inox

With Mikron Tool’s coated pilot or center drill CrazyDrill Pilot, centering and pilot drilling up to 2 × D can be accomplished in a single step. Subsequent drills are cylindrically guided within the pilot hole, resulting in excellent hole straightness. The precise alignment of the pilot drill’s point angle with the following drill protects the cutting edges and ensures process reliability.

The CrazyDrill Pilot is available from stock in diameters ranging from 0.40 mm to 6.35 mm (0.016" to 0.250", fractional inch sizes available).

Its special high-performance geometry guarantees high machining speeds, while the optimized coating extends tool life and maintains consistent drilling accuracy.


CrazyDrill Crosspilot Solid Carbide Drill

Product Overview

The CrazyDrill Crosspilot from Mikron Tool is a coated solid carbide drill designed for steel, stainless steel, titanium, and non-ferrous metals, and is a unique specialist for drilling on inclined, convex, and concave surfaces. It can directly machine pilot holes on surfaces with inclination angles up to 60°, which do not correspond to DIN center holes, since circular chamfers cannot be applied on inclined surfaces.

This means that the solid carbide drill reduces the previously required three steps (milling – centering – drilling) down to two steps, while ensuring higher precision thanks to excellent guidance. Its compact and robust design provides outstanding positioning accuracy, and its geometry is specifically engineered for extreme applications.

The 170° point angle of CrazyDrill Crosspilot ensures stability for subsequent drills, preventing cutting edge breakage. Pilot drills are available from stock in diameters ranging from 0.40 mm to 6.35 mm (0.016" to 0.250", fractional inch sizes available), fully compatible with the existing CrazyDrill program.
