Drilling and application conditions
The R and T values below apply only to the Ambrovit C1022 steel execution. R is an indicative laboratory value: speed, substrate thickness and strength must be checked for the application. Where T depends on length, capacity is specified for the requested execution.
| Diameter | R (rpm) | T (mm) / condition |
|---|---|---|
| 2,9 | 2.250 | 1,00 |
| 3,5 | 2.250 | To be determined from the point and required length |
| 3,9 | 2.250 | To be determined from the point and required length |
| 4,2 | 2.250 | To be determined from the point and required length |
| 4,8 | 2.250 | To be determined from the point and required length |
| 5,5 | 2.250 | 4,00 |
| 6,3 * | 2.250 | 6,00 |
Declared hardness for Ambrovit 81180: surface HV ≥ 560; core HV 270-425. Solid stainless executions for soft metals, such as aluminium, do not inherit case-hardened steel drilling values. Bimetallic screws require separate verification of the body and drill point.
Family references: DIN 7504 M (ex N); UNI 8118; ISO 15481. Check the edition and execution when ordering: catalogue references do not imply interchangeability of every dimension.
