Sandvik CoroDrill DS20 vs Seco Perfomax
CoroDrill DS20 and Perfomax are indexable-insert drills intended for productive, economical holemaking. DS20 is specifically positioned for secure drilling to 7xD without pilot drilling. Perfomax is a mature square-insert platform with four cutting edges and a broad diameter range in shorter depth ratios.
Side-by-side comparison
| Category | Sandvik CoroDrill DS20 | Seco Perfomax |
|---|---|---|
| Depth capability | Available for holes from 4xD through 7xD without a pilot drill. | Common Perfomax bodies are listed in 2xD, 3xD, 4xD and 5xD configurations. |
| Insert economy | Uses optimized central and peripheral inserts with four cutting edges and controlled chip evacuation. | Uses square multi-edge inserts with four cutting edges and grade/geometry choices for center and periphery. |
| Hole range | Designed around a defined indexable deep-hole envelope, with modular interface options and a newer stack-drilling solution. | Spans approximately 15-85 mm, depending on body and connection. |
| Process emphasis | Consistent hole diameter, process security and chip evacuation at longer indexable-drill depths. | General indexable productivity, polished body/flute design and broad material coverage through insert selection. |
| Entry strategy | The official 4-7xD concept eliminates pilot drilling under supported conditions. | Shorter bodies and established application variants make Perfomax a conventional choice for rigid, medium-to-large holes. |
Best fit by application
Sandvik CoroDrill DS20
- Use DS20 when the application requires indexable drilling beyond 5xD and avoiding a pilot operation has measurable value.
- Its stack-drilling option is relevant only within the diameter, plate-gap and setup limits.
Seco Perfomax
- Use Perfomax for broad medium-to-large diameter work within its shorter depth ratios and where four-edge square-insert economics are established.
- It fits shops already standardized on Seco insert grades, bodies and stationary-tool variants.
Selection notes
DS20 is the more direct choice for secure 4-7xD indexable drilling without pilot drilling. Perfomax remains a broad, economical platform for shorter medium-to-large holes.
Variables to validate
- Longer depth capability does not guarantee tighter tolerance or finish; both remain indexable drills.
- Normalize body diameter, length, insert grades, coolant pressure and machine stability during testing.
