Kennametal 3854756 Square End Mill 3/8 in 3 Flute Carbide

Product Description

The KENNAMETAL 3854756 is a solid carbide square end mill designed for precision milling in metal cutting applications. Built from micrograin carbide grade K600, this single-end tool features three right-hand spiral flutes with a 37-degree helix angle for efficient chip evacuation and stable cutting performance. The bright uncoated finish suits applications where coating is not required or where direct carbide-to-material contact is preferred. Licensed machinists and CNC operators install this tool in vertical and horizontal machining centers for slotting, profiling, and contouring operations.

This end mill is suited for use in general-purpose ferrous and non-ferrous machining environments. The centercutting geometry allows plunge entry into workpieces, expanding its use in pocketing and ramping operations. The 3/8 inch diameter and 7/8 inch length of cut make it well-matched to finish and semi-finish passes on small-to-medium features. It carries a right-hand cutting direction and right-hand flute orientation, consistent with standard spindle configurations on most CNC machining centers and manual mills.

Key Features

• Solid carbide construction with micrograin K600 grade for hardness and wear resistance
• 3-flute, right-hand spiral design with 37-degree helix angle for controlled chip flow
• Centercutting capability allows direct plunge entry without a pre-drilled pilot hole
• Bright uncoated finish suitable for applications not requiring thermal barrier coatings
• Single-end configuration with consistent shank and mill diameter of 3/8 inch
• No chipbreaker, no variable helix, no variable index — predictable, repeatable cutting geometry

Compatibility

Designed as a standard 3/8 inch shank square end mill for use in collet chucks, end mill holders, and shrink-fit toolholders that accept 3/8 inch straight shanks on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Secure the shank in a clean, properly sized collet or end mill holder to the minimum recommended engagement depth for the holder type. Verify runout with an indicator before beginning cuts. Do not exceed the rated length of cut when setting axial depth of cut, as overextension beyond the flute length reduces tool life and increases deflection risk.
