Walter-prototyp 7745630 Corner Radius End Mill Head 4 Flute

Product Description

The WALTER-PROTOTYP 7745630 is a solid carbide corner radius end mill head designed for precision milling operations in metalworking and machining applications. With 4 flutes and a right-hand spiral flute configuration, this head delivers clean, efficient material removal in right-hand cutting operations. The corner radius end type helps reduce stress concentration at the cutting edge, extending tool life and improving surface finish. At 0.30 inches length of cut and an overall length of 3.19 inches, it is sized for moderate-depth profiling and contouring work. Material grade WJ30TF indicates a coated carbide substrate suited for demanding cutting conditions. Licensed machinists and tooling technicians are the primary installers and operators of this component.

This end mill head is intended for use in CNC machining centers and manual milling machines where interchangeable head systems are employed. It is suited for profiling, slotting, and contouring operations on ferrous and non-ferrous materials. The fixed index, fixed helix geometry provides predictable, consistent cutting behavior across production runs. Typical applications include precision part manufacturing in aerospace, automotive, and general industrial shops requiring repeatable tool performance.

Key Features

• Solid carbide construction in material grade WJ30TF for hardness and wear resistance
• 4-flute, right-hand spiral design for efficient chip evacuation and smooth cutting
• Corner radius end type reduces edge chipping and improves workpiece surface finish
• 0.30 inches length of cut suited for moderate-depth profiling passes
• Right-hand cutting direction compatible with standard CNC spindle rotation
• Fixed index and fixed helix geometry for consistent, predictable performance

Compatibility

Designed as a replacement-style corner radius end mill head for interchangeable-head milling systems accepting this head diameter and thread configuration. Confirm spindle interface and head dimensions against your toolholder specifications before installation.

Installation Notes

Installation of end mill heads should be performed by qualified machinists or tooling technicians following the machine tool manufacturer's torque and interface specifications. Ensure the machine spindle is fully powered down and locked out before changing or seating the head. Use the appropriate wrench or torque tool specified for your toolholder system. Inspect the mating thread and seating surface for chips or damage before each installation to ensure proper runout and secure engagement.
