Value Collection 720-3033 Square End Mill 23/64 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3033 is a single-end square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Built from M2 high speed steel with a bright/uncoated finish, it features a 23/64 inch (0.3594 inch) cutting diameter and a 3/4 inch length of cut. The 4-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and delivers a smooth surface finish in profiling, slotting, and peripheral milling applications. This is a standard fractional-inch series (VC-HSS-4) tool suited for manual mills and CNC machining centers where HSS tooling is preferred over carbide.

This end mill is used in job shops, maintenance machining environments, and production setups where cost-effective HSS tooling is appropriate. The 3/8 inch shank diameter fits standard collets and end mill holders on vertical mills and machining centers. With a 2-1/2 inch overall length and regular length classification, it offers good rigidity for conventional milling depths. It is not center-cutting, so it is not suited for direct plunge entry — ramp entry or pre-drilled start holes are required for pocket work.

Key Features

• M2 high speed steel construction for durability across a range of workpiece materials
• 4-flute, right-hand spiral design with 30-degree helix angle for efficient chip removal
• Bright/uncoated finish — ready to use as-supplied, compatible with re-sharpening
• Single-end configuration with regular length for balanced reach and rigidity
• Not center-cutting — requires ramp or pre-drilled entry for pocket milling
• Fractional inch sizing: 23/64 inch diameter with 3/8 inch shank for standard toolholding

Compatibility

Designed as a standard fractional-inch replacement end mill for use in vertical milling machines and CNC machining centers accepting a 3/8 inch shank. Suitable wherever M2 HSS 4-flute square end mills are specified.

Installation Notes

Installation is performed by a machinist or toolroom technician using a standard end mill holder or collet chuck rated for the 3/8 inch shank diameter. Ensure the spindle is fully powered down and locked before changing tooling. Confirm runout with a dial indicator after seating the tool — excessive runout accelerates edge wear and reduces surface finish quality. Do not use this tool for direct plunge cuts; use ramp entry or pre-drilled holes when entering closed pockets.
