Need to drill large holes in stacked structures with reliable performance?
Many customers have highlighted the challenge of achieving consistent reliability when drilling through stacked components. The main issue? Preventing discs from forming and getting trapped between layers. These discs can lead to unexpected machine stops, scrapped parts, and even tool damage. Our R&D team took on this challenge and developed a dedicated solution for the indexable drill concept CoroDrill® DS20.
Introducing the CoroDrill® DS20 Stack Drilling Solution
After rapid prototyping and extensive internal testing, we defined a new central insert design. Field verification with European end users confirmed that the solution meets customer expectations.
With its innovative insert shape (see image), CoroDrill® DS20 now enables reliable drilling of holes from 28–52 mm (1.10–2.00 in) in stacked structures. The design allows for plate gaps up to 1.0 mm (0.04 in) without compromising performance.
The new L5S geometry is available in three insert sizes and fits seamlessly into the standard CoroDrill® DS20 assortment.
Why It Matters
Reduced machine output impacts cost efficiency. Our solution helps minimize downtime and scrap, improving overall productivity.
Indexable Insert Drilling at a Glance
Indexable insert drills are widely recognized as cost-effective tools. One key advantage in weak setups and components is their low axial cutting forces, compared to symmetric two-edge drill geometries. This is especially beneficial for stack drilling applications, such as welded structures, where stable fixturing can be difficult.
