Product families selected by machining task
These product sheets describe different tool and cutting material families: carbide drills for aluminium alloys, solid carbide drills for steel, PCD helical endmills, ceramic endmills and the Solid HBN series. Each workpiece material assignment is taken from the specific product sheet. The families are not interchangeable designs of one tool.
A suitable solution connects workpiece material with tool geometry, mounting, cooling and surface objectives. Product comparison therefore starts by checking the machining task actually described by the sheet.
Tools and design features
| Product family | Documented application | Feature described |
|---|---|---|
| ET110 carbide drills | Aluminium alloys | Polished surfaces; helical and burnishing designs |
| ET220 solid carbide drills | Steel | Ultra-fine carbide, coolant holes and coating variants |
| PCD helical endmills | Milling with PCD edges; workpiece material selected by application | High rake angle, carbide shank |
| EC2008 ceramic endmills | Heat-resistant superalloys / HRSA | SiAlON cutting material and adapted geometry |
| Solid HBN | Cast iron, especially roughing | EHWA PCBN grade series |
Chip flow, cutting edge and wear
The aluminium drill sheet describes polished tool surfaces to reduce built-up edge and support chip flow. The steel drill focuses on tool hardness, toughness, coolant holes and coating. These features belong to different tool tasks.
For PCD helical endmills, EHWA names high removal performance, good surfaces and sharp cutting edges as objectives. The EC2008 ceramic endmill sheet describes heat-resistant superalloy machining, including nickel alloys for turbine components. Geometry and number of flutes are coordinated with the application.
"HBN" in this sheet is an EHWA designation for a PCBN series. It is not translated as hexagonal boron nitride. Grade selection considers wear behaviour, surface objectives and mechanical loading.

Dimension letters and the value F follow the tool drawing and table. The examples describe individual designs and grade characteristics. They are not recommendations for an arbitrary machine or unspecified material. Complete product drawings remain essential to tool design.
