Indexable Drills
Wendeschneidplatten-Bohrwerkzeuge für 3xD-, 4xD- und 5xD-Tiefen, Ø14.0–44.0 mm.
Das Sortiment an Wendeschneidplattenbohrern von Galtona umfasst Werkzeuge und Wendeschneidplatten für Wendeschneidplattenbohrungen in den Tiefen 3xD, 4xD und 5xD, von Ø14.0 mm bis Ø44.0 mm.
Sie wurden als Leistungssteigerung für extreme Bearbeitungsbedingungen entwickelt – beispielsweise für Bohrungen durch Materialstapel, in Kanten, Ecken, Schweißnähte und geriffelte Oberflächen. Die identischen Innen- und Außenwendeschneidplatten reduzieren den Lagerbedarf und vereinfachen die Handhabung.
Vorteile: Bis zu 20 % höhere Schnittdaten und Vorschubgeschwindigkeiten, optimale Maßgenauigkeit auch unter schwierigen Bohrbedingungen und ein einziges Werkzeug, das Genauigkeit, Spitzenleistung und große Bohrtiefen vereint.
SOLT indexable inserts — steel, stainless, and cast-iron grades
SOLT Inserts, Grades & Cutting Data
Insert range by drill diameter, coating grades, and recommended cutting parameters.
All three drill lengths (3×D, 4×D, 5×D) share the same SOLT indexable insert across seven pocket sizes, selected by drill diameter via the insert-circle (IC) size below. Each pocket size is available in four chip-groove/grade combinations: …-HCD (GTPP425, steel), …-CCD (GTPK415, cast iron), …-SCD (GTPP440, stainless), and …-HCD (GTPP440, super alloys).
