High-performance drills specially designed for aluminium
The KOMET KUB® Drillmax XL ALU is designed for machining aluminium and has optimised cutting edge and flute geometry. The drill is optimally centred and guided by the additional lands, which guarantees a high degree of alignment accuracy. The flutes have been additionally polished, which provides reliable
chip removal from the hole to a depth of 40×D.
Application example:

Deep-hole drilling, dia. 5.0 mm in aluminium, MQL
Material: AlSi12Cu1
Workpiece: Ladder frame
Hole: x 5.0 mm, 36×D deep after cylindrical countersink
Machine: Machining centre, vertical
Minimum quantity lubrication 10 bar (MQL)
Tool: KOMET KUB® Drillmax XL ALU
Ø 5.0 mm tool designed for 40×D
6xD pilot hole required
Cutting values:
vc = 100 m/min = 6370 rpm
f = 0.12 mm/rev

Machining: Plunging in pilot hole at reduced speed and with reduced feed. Continued drilling with two pauses, then down to end of hole depth at reduced speed and with reduced feed. Retraction from the finished hole at reduced speed.

Conclusion: In comparison to the competition, it was possible to increase tool
life from 6000 to 10,000 holes (1.802 m). Application runs reliably.

Your PLUS:

Optimally matched cutting edge geometry
Polished flutes
Internal coolant supply for MSS or KSS
Reliable drilling to a depth of 40×D without pecking
High degree of alignment accuracy
