ISCAR SUMOCHAM

Product system overview

ISCAR SUMOCHAM is a ISCAR tooling system used in replaceable-head drilling. 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.

Industries and applications

• 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.
• Use SUMOCHAM when the application benefits from ISCAR's broad exchangeable-head geometry selection and solid-drill-like cutting profile.
• It is attractive when a single body program must support several material-specific head styles or miniature/deep-hole variants.
• Choose SUMOCHAM when material-specific point geometry or broad exchangeable-head/body choice is more valuable.
• Its miniature and deep-hole extensions make it easier to stay within one exchangeable-head family across varied work.

Published technical profile

• System architecture: One exchangeable carbide drilling head locks into a reusable body with internal coolant.
• Geometry strategy: Four standard head geometries target steel, exotic materials, cast iron and aluminum, with additional head styles in the broader line.
• Operation scope: Primarily a high-productivity drilling system; related SUMOCHAM bodies and heads cover standard, small-diameter and deep-hole variants.
• Diameter character: A broad exchangeable-head family, including miniature PICCO-SUMOCHAM variants from 4–10 mm and larger standard systems.
• Hole-making behavior: Head geometry approximates a solid drill cutting edge and avoids managing separate center and peripheral inserts.
• Cutting-unit design: Exchangeable solid-carbide drilling head locked into a reusable coolant-through body.
• Application emphasis: Solid-drill-like holemaking with head geometries selected for steel, stainless and exotic alloys, cast iron or aluminum.
• Platform continuity: Body and head compatibility depends on SUMOCHAM diameter family, head style and drill depth.
• Geometry selection: Multiple head geometries and subfamilies address general drilling, small diameters, deep holes and application-specific points.
• Special operations: SUMOCHAM's strength is the breadth of exchangeable-head drilling choices rather than a single combined-operation holder concept.
• Cutting unit: Exchangeable solid-carbide drilling head locked into the body pocket.
• Standard range: Broad exchangeable-head range with standard, miniature and deep-hole subfamilies.
• Geometry strategy: Multiple head geometries for steels, stainless/exotic alloys, cast iron, aluminum and special entries.
• Difficult conditions: ISCAR offers dedicated point styles and body choices; exact head selection controls edge behavior.
• Inventory model: Large head-and-body ecosystem offering more geometry choices but requiring disciplined compatibility control.

Selection notes

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.

Use SUMOCHAM when the application benefits from ISCAR's broad exchangeable-head geometry selection and solid-drill-like cutting profile.

It is attractive when a single body program must support several material-specific head styles or miniature/deep-hole variants.

Choose SUMOCHAM when material-specific point geometry or broad exchangeable-head/body choice is more valuable.

Its miniature and deep-hole extensions make it easier to stay within one exchangeable-head family across varied work.

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.

GEN3SYS XT has the clearer case for Allied high-penetration and structural applications; SUMOCHAM has the clearer case for a broad exchangeable-head geometry ecosystem. Select the exact cutting unit and body, not the umbrella family name.

KSEM is the more compact stability-focused modular system; SUMOCHAM is the broader geometry ecosystem. Select the exact insert or head before comparing price or performance.

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.
• Confirm exact holder generation and insert or head compatibility before treating either system as interchangeable.
• Compare the same diameter, depth ratio, coolant condition, entry condition and hole-quality requirement.
• The systems use different head/insert interfaces and consumable economics.
• Normalize diameter, depth, coolant, runout and hole tolerance in any trial.
