Reliable corner rounding for professional milling operations

The 4-flute Solid Carbide Corner Rounding Cutter with PVD coating is designed to produce exact radii and clean edges. Featuring a 0° helix angle, this tool ensures precise profile machining without distortion. The integrated Weldon shank provides a secure and firm grip, preventing pull-out during demanding operations.

Advantages of Solid Carbide Corner Rounding Cutter

PVD-coated fine-grain carbide (RT303) promotes high wear resistance in general milling applications
Four-flute design helps achieve smooth, chatter-free cuts and clean surface finishes
Stable profile machining supported by the straight-fluted 0° helix angle
Weldon shank ensures maximum holding security to prevent tool pull-out

Description

Applications

This cutter is specifically developed for edge rounding in CNC manufacturing. The 0° helix angle supports a straight cut, which ensures high profile accuracy when milling outer edges on complex components. The tool geometry and carbide grade are optimized for versatile machining in mold, machine, and tool making, enabling clean radii on parts made of steel, stainless steel, cast iron, or non-ferrous metals.

Special features

The PVD coating of the RT303 carbide effectively protects the tool against premature wear, supporting long service lives across a wide range of materials. With its non-centre cutting geometry, the cutter focuses entirely on external profile machining. Additionally, the form-fitting Weldon shank provides maximum security against tool pull-out, safeguarding machining quality under challenging conditions.
