CoroDrill® DE10
The exchangeable-tip drill for high-volume hole making
Apply 3–8×DC drills
There is no difference in applying 3×D or 8×D regarding feed recommendations. The applied cutting data should be within the recommendations.

Find the latest updated cutting data for all material groups and articles in CoroPlus® Tool Guide. Set the workpiece parameters and the system generates starting point cutting data.
Mounting key
A mounting key is included in each drill box and covers the complete drill range. The mounting key gives great visibility during the assembly process and is easily recyclable.
Order no: 5680 300-01
Plastic cover with collars
The plastic cover improves ergonomics and avoids splinter risks of carbide. The see-through design and guiding collars make it easy to use.

Assembly instruction
- Lubricate the contact surfaces before mounting the drill tip to maximize the interface tool life.
- Place the drill tip into the tip seat ~60 degrees twisted from the final position. Position the key in the key grips.
- Mount/unmount the tip.
Grade and geometry recommendations
-M5 geometry
- One geometry for all materials
Grade GC4334
- Tough, high Cr content and fine-grained substrate with PVD coating (AlTiN) produced with Zertivo® technology
- High reliability with high edge security provides resistance against built-up edge and chipping
Grade GC2334
- Tough, high Cr content and fine-grained substrate with thin multi-layer PVD coating (AlTiCrN) produced with Zertivo® technology
- For high reliability and improved resistance against chipping and flaking on land margin
Through hole recommendations
When drilling through holes with -M5 geometry, use point length (PL) + 1 mm (0.039 inch) to ensure the drill tip is completely through the hole exit. The exact PL value is found on the article’s web page.

Advanced operations
Note: These advanced operations are not recommended, but if necessary, follow the guidelines below. Results may vary depending on workpiece material and drill length.
| Angled surface entry | Angled suface exit | Convex surface | Concave surface | Cross holes | |
| Preconditions | Angle ≤ 10º | Angle ≤ 30º | Minimum radius of surface: 4×DC | Minimum radius of surface: 1×DC | Minimum recommended diameter on the hole to be crossed: 2×DC |
| Cutting speed, vc | Use the recommended value for the workpiece material | ||||
| Feed, fn | Start value; reduce to 1/3 of recommended feed rate | ||||
Run-out recommendations
Run-out is affected by for example machine condition, holder and mounting.
Preferable: ≤ 0.03 mm (0.0012 inch)
Acceptable: ≤ 0.06 mm (0.0024 inch)
Not acceptable: > 0.06 mm (0.0024 inch)
Turning applications
In non-rotating drill applications, a large misalignment greatly affects process security and tool stability. Always follow these recommendations.
Preferable ≤ 0.10 mm (0.0039 inch)
Acceptable ≤ 0.20 mm (0.0079 inch)
Not acceptable > 0.20 mm (0.0079 inch)
Coolant recommendations
- Internal coolant is recommended for safe chip evacuation
- Apply sufficient coolant flow and follow the recommendation on emulsion concentration from your supplier
- When drilling deep holes, sufficient coolant flow is crucial to enable proper chip evacuation
Recommended minimum cutting fluid flow
