ISCAR SUMOCHAM vs Sandvik CoroDrill 880
SUMOCHAM and CoroDrill 880 are not the same type of drill. SUMOCHAM is an exchangeable solid-carbide-head system designed to deliver solid-drill-like hole quality with a reusable body. CoroDrill 880 is an indexable insert drill with separate central and peripheral cutting edges and broader multifunction capability.
Side-by-side comparison
| Category | ISCAR SUMOCHAM | Sandvik CoroDrill 880 |
|---|---|---|
| System architecture | One exchangeable carbide drilling head locks into a reusable body with internal coolant. | Indexable drill using central and peripheral inserts; two or four cutting edges are available depending on diameter. |
| Geometry strategy | Four standard head geometries target steel, exotic materials, cast iron and aluminum, with additional head styles in the broader line. | Central/peripheral insert geometries and grades are selected independently to balance chip formation, surface finish and wear. |
| Operation scope | Primarily a high-productivity drilling system; related SUMOCHAM bodies and heads cover standard, small-diameter and deep-hole variants. | Officially supports drilling plus helical interpolation, boring, plunging and turning. |
| Diameter character | A broad exchangeable-head family, including miniature PICCO-SUMOCHAM variants from 4–10 mm and larger standard systems. | The standard CoroDrill 880 assortment is listed for approximately 12–84 mm holes. |
| Hole-making behavior | Head geometry approximates a solid drill cutting edge and avoids managing separate center and peripheral inserts. | Wiper geometry and optimized chip channels support surface finish, feed capability and chip evacuation in an indexable format. |
Best fit by application
ISCAR SUMOCHAM
- Use SUMOCHAM when exchangeable-head simplicity and solid-drill-like cutting geometry are preferred.
- It is attractive where frequent head replacement is easier to manage than separate center/periphery insert inventories.
- Select the head geometry explicitly for ISO material group and entry condition.
Sandvik CoroDrill 880
- Use CoroDrill 880 when larger-diameter indexable economics or multifunction operations matter.
- It is the clearer choice when the process may use the same platform for interpolation, boring, plunging or turning in addition to drilling.
- Its independent central and peripheral insert strategy offers more tuning freedom but requires more setup discipline.
Selection notes
Prefer SUMOCHAM for exchangeable-head drilling where a solid cutting profile and simple head change are valuable. Prefer CoroDrill 880 for indexable drilling, larger holes and multifunction work where separate insert optimization is acceptable.
Variables to validate
- The tools have different architectures, so cost-per-edge comparisons are misleading without complete assembly and cycle data.
- SUMOCHAM head style and CoroDrill center/periphery grade combinations must each be matched to material and conditions.
- Hole tolerance, finish, breakout and machine stability should be compared using exact diameters and equivalent depth ratios.
