Mapal Launches Second-Generation Deep Hole Drill
The new Mega-Deep-Drill-Alu tool targets aluminium deep hole drilling with updated geometry, cooling and cutting material.
Updated on Nov. 3, 2026 in Materials Science
Mapal has released the second-generation Mega-Deep-Drill-Alu for aluminium deep hole drilling. The tool combines new cutting edge geometry, cooling channel design and an uncoated cutting material, and was tested extensively with end-users.
Why it matters
The redesign targets stable deep hole machining in aluminium, where chip evacuation and cooling strongly affect process reliability. Improvements in feed rate and tool life can affect production efficiency for manufacturers using deep hole drilling.
Manufacturer-reported end-user trials achieved feeds of up to 0.4mm per revolution and tool lives of up to 3.2 kilometres. The source does not provide a baseline against the first-generation tool or the specific test conditions.
The players
Mapal
Mapal is a German precision tooling manufacturer known for drilling and reaming tools used across automotive and industrial machining.
The details
The tool features a straight main cutting edge, double point thinning, optimised chip flutes and four guide margins that stabilise the process at cross bores or angled exits. Newly defined cooling channels, enlarged by 20%, direct more coolant to the main cutting edge and corners, and the tool is offered in lengths from 15×D to 40×D and diameters from 3 to 16mm.

Big Picture
The second-generation Mega-Deep-Drill-Alu extends Mapal's first-generation Mega-Deep-Drill-Alu line, adding a redesigned geometry, enlarged cooling channels and an uncoated cutting material. The source does not provide a direct comparison of performance figures against that predecessor.
Manufacturers machining deep holes in aluminium may see the tool's reported feed and tool-life gains as a possible route to higher throughput. Shop floors evaluating the tool would need to assess the reported trial results against their own materials and machine conditions.
The takeaway
Reported gains in feed rate and tool life suggest the redesign targets chip evacuation and cooling in deep hole aluminium drilling. Machinists should validate these figures under their own cutting conditions before adopting the tool.
