Description

SK40 Indexable Drill Holder, Weldon

Maximum process reliability starts at the interface. The SK40 solid-drill holder with Weldon mount to DIN 69871 has been developed specifically for demanding machining tasks where precision, stability and durability are critical.

The Weldon mount ensures a positive torque drive and prevents tool slippage even under high cutting forces. Thanks to the robust reinforced inner wall, vibrations are effectively damped, which not only improves dimensional accuracy but also protects cutting edges. The integrated through-bore enables targeted internal coolant supply, significantly optimizing chip evacuation and tool life.

With a guaranteed runout accuracy of ≤ 0,005 mm, H6 bore tolerance and heat-treated steel construction, this holder meets the highest demands in modern CNC machining centres and milling machines. DIN 69871 compliance ensures seamless integration into existing toolholder systems.

For machine builders and machining professionals who expect uncompromising precision and maximum performance, this SK40 solid-drill holder is the first choice.

technical specification of the SK40 tool holder with Weldon clamping system per DIN 69871: heat-treated steel (42CrMo4), H6 tolerance, through-bore for internal coolant, runout accuracy ≤ 0.005 mm, case depth 0.8–0.9 mm, surface hardness HRC 55–56

Vollbohrer-Aufnahme mit Weldon-Spannung bei uns bewährt

Die Vollbohrer-Aufnahme mit Weldon-Spannfläche habe ich auf unserer Mazak VCN-530C in verschiedenen Bohraufgaben eingesetzt. Die Spannung hält auch bei höheren Schnittkräften zuverlässig, die Wiederholgenauigkeit zwischen Werkzeugwechseln ist ausgezeichnet. Der Werkzeugkörper wirkt sauber gefertigt und sitzt spielfrei in der Maschinenaufnahme. Für unsere Vollbohrer eine wichtige Basis, die den Bohrprozess sicher macht.
