Kennametal 6676562 Corner Radius End Mill 1 in 4 Flute

Product Description

The KENNAMETAL 6676562 is a solid carbide corner radius end mill designed for high-performance milling in demanding metalworking applications. With a 1-inch cutting diameter, a 0.12-inch corner radius, and a 2.25-inch length of cut, this single-end tool is built for both roughing and finishing passes. The 4-flute, right-hand spiral geometry is paired with a PVD-applied AlTiN coating, which delivers elevated heat resistance and extended tool life when cutting abrasive or hard materials. The Weldon flat shank provides secure tool holding in compatible EM-CV and EM IN-HSK toolholders.

This end mill is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials in production and job-shop environments. It belongs to the H1TE series, which is engineered for general-purpose to high-demand cutting cycles. The centercutting design allows plunge entry, and the standard-pitch, non-variable-helix flute geometry supports consistent chip evacuation across a range of feed and speed conditions. Licensed machinists and CNC operators handling ferrous and exotic-alloy workpieces are the primary end users for this tool.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN PVD coating provides high-temperature oxidation resistance, extending tool life in dry and semi-dry cutting
• 0.12-inch corner radius reduces stress concentration at the cutting edge and improves surface finish on profiled features
• Centercutting geometry allows direct plunge entry without pre-drilling
• Weldon flat shank for positive rotational drive in compatible toolholders
• Right-hand cutting, right-hand flute direction with normal pitch for predictable chip flow

Compatibility

Designed for use with EM-CV Form AD and EM IN-HSK Form A toolholding systems. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials as designated by material codes P, M, K, S, and H.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Confirm the toolholder bore and retention style are compatible with the 1-inch Weldon flat shank before mounting. Verify spindle runout is within acceptable tolerance prior to cutting to prevent premature edge wear. Always disengage spindle power and bring the machine to a complete stop before changing or inspecting tooling.
