Accurate and efficient drilling from Ø 0.2 mm

Drilling:

CrazyDrill Titanium TN / TK 

Because of the high degree of self-centering capability, CrazyDrill Titanium TN / TK can be used on regular and straight surfaces without a centering or pilot hole.

Higher requirements: for irregular respectively rough or inclined surfaces or for the highest degree of position accuracy Mikron Tool recommends:

• CrazyDrill Twicenter as center drill
• CrazyDrill Crosspilot as pilot drill for inclined surfaces

Centering / pilot drilling and drilling

Centering with CrazyDrill Twicenter is the perfect combination for a precise hole in term of position accuracy and a stable machining process.

The pilot drill CrazyDrill Crosspilot does the same when drilling on inclined surfaces.

The drilling quality is also guaranteed due to predetermined tool tolerances.

Tolerance pilot drill CrazyDrill Crosspilot (inclined surfaces) (k6): 
≤ 3 mm (.118”): + 0 mm /+ 0.006 mm (+ 0” /+ .00024”)
≤ 6 mm (.236”): + 0.001 mm /+ 0.009 mm (+ .00004” /+ .0004”)
≤ 6.35 mm (.250”): + 0.001 mm /+ 0.010 mm (+ .00004” /+ .0004”)

General information

In the industry of metal work tools, shorter processing times are always in high demand. At the same time, the requirements to the manufacturing precision and the process reliability are extremely high. In order to fulfill these requirements, the «machine tool – spindle – tool – tool holder» system need to be considered as a whole (see additional info). 

For the use of the types of drill bits CrazyDrill Titanium TN / TK and CrazyDrill Twicenter resp. CrazyDrill Crosspilot, Mikron Tool has defined a fast and process-reliable procedure which achieves optimum drilling results.

Centering or Pilot Drilling

Pilot drilling

• With CrazyDrill Twicenter (irregular or rough surfaces) or CrazyDrill Crosspilot (inclined surfaces). 

Drilling according DIN 66025 / PAL 
G83 deep-drilling cycle with chip break and chip removal
Q1 = depth of first peck, see cutting data table
Qx = depth of following pecks, see cutting data table

Short Drilling or Drilling

• With CrazyDrill Titanium TN / TK 3 x d and 6 x d up to maximum drilling depth Q1 in in one step, followed by peck to remove chips.

• Further pecks Qx according to cutting data table, followed by peck to remove chips.

Note:

Between pecks, take the drill completely out from the hole. After the drill reached desired cutting depth, return at increased feed rate (or in case of perfect conditions rapid traverse) to safety position.

Mikron Tool has determined the ideal cutting parameters (drilling speed to tool life ratio and process reliability) when using CrazyDrill Titanium TN/TK. These are listed in the cutting data tables according to drill diameter, drilling depth and material to be machined. The detailed cutting data tested by Mikron Tool, such as cutting speed vc, feed rate f and drilling impact Q, permit a quick and secure machining.

The overview of the cutting values table according to material group, material type, hardness degree and tensile strength, material number, DIN and AISI/ASTM/UNS permits quick determination of the parameters to be used.

An impact-resistant and user-friendly drill packaging is absolutely necessary for CrazyDrill Titanium TN/TK. Mikron Tool offers all tools of the CrazyDrill Titanium family in a high quality, single package.
