RUKO GMBH KEB-HM-Weldon-22.0mm End Mill Holder

CNC machinists use the RUKO KEB-HM-Weldon-22.0mm end mill holder to clamp cylindrical shank cutting tools with a 22.0 mm diameter in milling and machining centers. The holder's Weldon interface (DIN 1835-B) uses a set screw against a flat on the tool shank to prevent rotation and pull-out during heavy cuts.

Key specifications

• Tool clamping diameter: 22.0 mm
• Tool shank interface: Weldon (DIN 1835-B)
• Holder series: HM
• Material: High-grade alloy tool steel
• Balancing grade: G2.5 at 25,000 rpm
• Runout accuracy: ≤ 0.003 mm
• Clamping mechanism: Set screw with Weldon flat
• Coolant delivery: External
• Surface finish: Precision ground
• Standard compliance: DIN 1835-B (for Weldon flat)

Why choose it

This holder is precision ground for high concentricity and balanced to G2.5 at 25,000 rpm, making it suitable for high-speed machining. The Weldon clamping system provides secure tool retention for cylindrical shank end mills.

Ideal use cases

• Securing end mills with Weldon flats in CNC milling machines
• High-speed machining operations requiring balanced toolholders
• External coolant applications in machining centers

Good to know

The holder is made from high-grade alloy tool steel and complies with DIN 1835-B for Weldon flat dimensions. No machine spindle interface is specified by the EAN; verify compatibility with your machine spindle before purchase.
