Value Collection 722-3099 Square End Mill 1 in 4 Flute Hss

Product Description

The VALUE COLLECTION 722-3099 is a single-end, square-profile end mill designed for milling operations in ferrous and non-ferrous metals. Built from M2 high speed steel with a titanium nitride (TiN) coating, it provides increased surface hardness and extended tool life compared to uncoated HSS. The 1-inch cutting diameter and 4-flute spiral geometry deliver a balance of material removal rate and surface finish quality. With a 30-degree helix angle and right-hand cut with right-hand flute direction, this end mill suits conventional slotting, profiling, and peripheral milling tasks on manual mills and CNC machining centers.

This end mill is intended for use in machine shops, tool rooms, and production environments where standard fractional-inch tooling is required. The regular-length configuration with a 1-7/8-inch length of cut and 4-inch overall length fits typical knee mills, vertical machining centers, and similar setups using a 1/2-inch shank holder. It is not center-cutting, making it suitable for side milling and profiling but not for direct plunge entry. Licensed machinists and CNC operators are the primary installers and users of this tooling.

Key Features

• M2 high speed steel construction for toughness and wear resistance in general-purpose milling
• TiN (titanium nitride) coating increases surface hardness and reduces friction at the cutting edge
• 4-flute spiral design balances chip evacuation with finish quality on ferrous materials
• 30-degree helix angle for smooth cutting action and reduced chatter
• Right-hand cut, right-hand flute orientation — standard configuration for most vertical milling setups
• Non-center-cutting geometry — designed for peripheral and slot milling, not plunge entry

Compatibility

Designed as a standard fractional-inch replacement or stock end mill for use in 1/2-inch collets, end mill holders, or compatible tool holders on vertical knee mills, bridge mills, and CNC machining centers. Part of the VC-HSS-4-TN series.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with tool holding and feeds-and-speeds selection for HSS end mills. Ensure the machine spindle is fully stopped and locked before changing tooling, and confirm the tool holder is clean and free of debris before seating the shank. Do not use this tool for plunge cutting, as it is not center-cutting. Follow the machine manufacturer guidelines and applicable shop safety protocols when setting cutting parameters.
