ISCAR SUMOCHAM

ISCAR SUMOCHAM is an exchangeable solid-carbide drilling-head system built around reusable drill bodies, replaceable heads, internal coolant, and application-specific head geometries and grades. Diameter, head code, body code, drilling depth, connection, and coolant arrangement must remain linked.

Product system overview

ISCAR SUMOCHAM is an exchangeable solid-carbide drilling-head system built around reusable drill bodies, replaceable heads, internal coolant, and application-specific head geometries and grades. Diameter, head code, body code, drilling depth, connection, and coolant arrangement must remain linked.

Industries and applications

  • Production drilling where worn heads can be changed without replacing the drill body.
  • Modular and long-overhang configurations, including SUMOCHAM bodies with MULTI-MASTER connections for compact and Swiss-type machines.
  • Material-specific holemaking using the head geometry and grade for the selected body and L/D series.

Technical and quote details

  • ISCAR describes exchangeable solid-carbide heads mounted in steel drill bodies with internal coolant delivery.
  • SUMOCHAM ranges include multiple L/D series, head geometries, grades, and body configurations.
  • The MULTI-MASTER-connected SUMOCHAM branch expands shank and overhang options but does not make every component universally interchangeable.
  • Body selection must retain diameter range, drilling depth, shank or thread connection, flute form, and coolant arrangement.
  • Head selection must retain diameter, interface code, cutting geometry, carbide grade, and material application.
  • Compatibility, lineage, or lifecycle crosswalk: body-to-exchangeable-head to SUMOCHAM head matching the specified body pocket and diameter range (conditional). Match body designation, head interface, cutting diameter, geometry, grade, drilling depth, coolant, and tightening instructions.

Selection notes

Store drill body and head as separate products joined by an evidence-backed compatibility record, including diameter, L/D, material group, coolant, and connection.

Attach tightening, coolant, and cutting-data instructions to the exact assembly used in production.

Variables to validate

  • Head diameter alone does not establish pocket, body, grade, geometry, or drilling-depth compatibility.
  • Confirm the current catalog combination and tightening procedure before substituting a head or body.
  • Do not apply a MULTI-MASTER connection or overhang limit to a straight-shank body without item-level evidence.
