Walter-prototyp 8417196 Square End Mill 1 in 4 Flute Carbide

Product Description

The WALTER-PROTOTYP 8417196 is a 4-flute solid carbide square end mill designed for high-performance milling in demanding materials. With a 1 inch mill diameter, a 4.25 inch length of cut, and a 7 inch overall length, this tool is built for deep-reach profiling and slotting operations. The nACRo coating provides heat and wear resistance suited to dry or near-dry cutting. A 38-degree helix angle promotes efficient chip evacuation and smooth cutting action. This tool is primarily used on superalloys and titanium, with secondary capability in stainless steel and general steel applications. It is installed and operated by machinists and CNC programmers working in aerospace, energy, and precision manufacturing environments.

The 8417196 is intended for use in CNC machining centers requiring a center-cutting, right-hand spiral end mill capable of extended-reach cuts in difficult-to-machine materials. The straight-cylindrical shank with h6 tolerance provides a secure, accurate fit in standard end mill holders and shrink-fit chucks. This tool belongs to the MA377.A-4 series and is suited to applications where tool life and edge stability in superalloys and titanium are the primary concerns. Typical setups include full-depth side milling, slotting, and profiling passes in aerospace structural components and turbine hardware.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• nACRo coating for elevated thermal protection and extended tool life in superalloys and titanium
• 38-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• 4.25 inch length of cut enables deep-reach profiling without tool changeover
• Center-cutting geometry allows plunge entry as well as peripheral milling
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Shank diameter tolerance h6 ensures precise fit in collet and shrink-fit toolholders

Compatibility

Designed as an OEM-style replacement and direct-fit end mill for CNC machining centers using 1 inch straight-cylindrical shank toolholders with h6 tolerance. Primary workpiece compatibility is superalloys and titanium (material code S); secondary compatibility includes stainless steel and general steel (material codes M and P).

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the tool. Verify holder bore cleanliness and shank condition before seating to maintain runout specifications. Follow the toolholder manufacturer torque and pull-stud guidelines; do not exceed the recommended gauge-line overhang for the selected holder type.
