Kennametal 6113326 Corner Radius End Mill 3/4 in 6 Flute

Product Description

The KENNAMETAL 6113326 is a solid carbide corner radius end mill engineered for demanding material removal and finishing operations in ferrous and high-strength alloys. It carries a 3/4 inch mill diameter, a 0.19 inch corner radius, and six right-hand spiral flutes with a high 38-degree helix angle. The AlTiN PVD coating delivers oxidation resistance and hardness retention at elevated cutting temperatures, making this tool well-suited for long-reach finishing passes where heat buildup is a concern. With an extra-long 6.5 inch overall length and a 4 inch length of cut, it reaches deep cavities that standard-length end mills cannot access. Licensed machinists and tooling specialists install and qualify this tool in production environments.

This end mill is designed for finishing applications in steel, stainless steel, superalloys, titanium, and hard materials. Its submicron carbide grade and close pitch flute geometry support tight surface finish tolerances in mold and die work, aerospace component machining, and general CNC milling of difficult-to-cut alloys. The centercutting geometry allows plunge entry, adding setup flexibility. It is compatible with hydraulic toolholders including HC 1/2 through HC 1-1/4 hydraulic sleeves with inch bores, HC 20M through HC 32M hydraulic sleeves metric with inch bores, and HC-HSK Form A holders.

Key Features

• Solid carbide submicron grade construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating rated for high cutting temperatures in steel, stainless, and superalloys
• 6-flute close-pitch design optimized for finishing passes with high material removal rates
• Extra-long 4 inch length of cut for deep-cavity and extended-reach milling applications
• 38-degree high helix angle reduces cutting forces and improves chip evacuation
• Centercutting geometry permits plunge entry without a pre-drilled pilot hole

Compatibility

Designed for use with HC 1/2 through HC 1-1/4 hydraulic sleeves with inch bores, HC 20M through HC 32M hydraulic sleeves metric with inch bores, and HC-HSK Form A toolholders. Intended for CNC machining centers running steel, stainless steel, superalloys, titanium, and hard materials per material codes P, M, S, and H.

Installation Notes

Installation and qualification of carbide end mills should be performed by a qualified machinist or tooling technician. Verify toolholder runout is within acceptable limits before clamping, as excessive runout accelerates edge wear on multi-flute finishing tools. Confirm spindle and toolholder are clean and free of chips or debris before seating the shank. Review machine shop safety protocols and applicable facility standards before operating at cutting parameters appropriate for this tool diameter and reach ratio.
