Description

HSK63A Indexable Drill Holder, Weldon

When it comes to precise drilling at high spindle speeds, the HSK63A solid-drill holder with Weldon mount to DIN 69893 sets new standards. Thanks to the positive, non-slip Weldon clamping, the tool is securely retained – even under extreme cutting forces.

The reinforced internal geometry provides maximum rigidity and minimizes vibration, resulting in excellent dimensional accuracy and extended tool life. With runout accuracy of ≤ 0.003 mm, this holder meets the highest precision requirements in modern machining.

The integrated through-bore enables direct internal coolant supply (IKZ), optimizing chip evacuation and heat dissipation. Manufactured from case-hardened quality steel, the holder offers a wear-resistant surface with a tough core for maximum process reliability. The H6 bore tolerance ensures a durable, precise fit – ideal for CNC machining centres requiring both speed and process stability.

This HSK63A solid-drill holder is the first choice for anyone seeking maximum drilling performance, dimensional accuracy and tool life in high-performance machining.

Werkzeugaufnahme für Vollbohrer sehr präzise

Die hochdrehzahl-taugliche Aufnahme läuft bei uns am VHM-Vollbohrer sehr präzise. Der Rundlauf ist top, der Weldon-Sitz klemmt sicher und die Verarbeitung überzeugt. Sinnvolle Anschaffung für moderne Spindeln.

Vollbohrer-Aufnahme im Bearbeitungszentrum bewährt

Die Vollbohrer-Aufnahme auf unserer DMG MORI DMU 50 hält die Wendeplattenbohrer auch bei höheren Schnittgeschwindigkeiten sauber in Position. Die Weldon-Spannung ist deutlich besser als bei einfachen Spannzangen, die Wiederholgenauigkeit zwischen Werkzeugwechseln ist ausgezeichnet. Auch nach vielen Bohrzyklen kein Spiel, keine Abweichungen in der Tiefe.
