Value Collection 851-0062 Square End Mill 1/16 in 4 Flute Hss

Product Description

The VALUE COLLECTION 851-0062 is a double-end, four-flute square end mill manufactured from high speed steel (HSS). It carries a 1/16 inch (0.0625 inch) cutting diameter with a 7/32 inch (0.2188 inch) length of cut and a 3/16 inch (0.1875 inch) straight shank. Overall length is 2-1/2 inches. The uncoated, bright finish makes it straightforward to inspect for wear. With a 30-degree helix angle and right-hand cutting and flute direction, this tool suits precision milling operations in a machine shop or toolroom environment. It is installed and operated by machinists and CNC operators working with light-duty cutting applications.

This end mill is suited for milling small features, slots, and profiles where a fine cutting diameter is required. The double-end configuration extends tool life by providing two usable cutting ends before the tool is retired. The long-length designation and spiral flute geometry make it appropriate for applications requiring reach into narrow pockets or for fine detail work on ferrous and non-ferrous materials at controlled feeds and speeds.

Key Features

• Double-end design provides two cutting ends for extended tool service life
• 4-flute spiral configuration for efficient chip evacuation in slot and profile milling
• 30-degree helix angle balances cutting forces and surface finish
• Right-hand cut and right-hand flute direction for standard spindle operation
• Bright/uncoated finish allows easy visual inspection of cutting edge condition
• Straight shank fits standard collets and end mill holders

Compatibility

Designed as an OEM-style replacement or direct-use end mill for standard collet chucks and end mill holders accepting a 3/16 inch straight shank, compatible with manual mills and CNC machining centers requiring a 1/16 inch cutting diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before loading or changing the tool. Secure the shank firmly in a clean, properly sized collet or end mill holder to the appropriate torque per the holder manufacturer guidelines. Verify runout with a dial indicator before beginning a cut, as excessive runout at this small diameter will accelerate edge wear and affect dimensional accuracy.
