Harvey Tool 973808-C6 Square End Mill 1/8 in 4 Flute Carbide

Product Description

The HARVEY TOOL 973808-C6 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. At 1/8 inch in diameter with a 3/16 inch length of cut and 1-1/2 inch overall length, this single-end tool is built for tight-tolerance applications where rigidity and cutting performance are critical. The 34-degree variable helix geometry reduces chatter and harmonics during aggressive cuts. An AlTiN coating increases surface hardness and heat resistance, extending tool life in high-temperature cutting environments. Machined from solid carbide throughout, it holds dimensional stability under demanding feed rates and depths.

This end mill is suited for CNC milling operations in tool and die, medical device, aerospace component, and precision part manufacturing. The 1/8 inch shank diameter matches directly to ER collets and other standard toolholding systems commonly found on vertical machining centers and high-speed spindles. Its compact geometry makes it well-suited for slotting, profiling, and finishing passes in confined features and small-bore cavities.

Key Features

• Solid carbide construction for maximum rigidity and tool life
• 34-degree variable helix reduces vibration and chatter during cut
• AlTiN coating provides heat resistance and extended wear life
• 4-flute configuration supports higher feed rates and improved finish quality
• Centercutting design allows plunge entry into the workpiece
• Right-hand cut and right-hand flute orientation for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement for 1/8 inch diameter solid carbide square end mill applications in standard ER collet and precision toolholding systems.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Secure the shank in a properly sized collet or toolholder to the manufacturer-specified clamping torque for the holder type in use. Verify runout at the tool tip before beginning a cut. Inspect the cutting edges for chipping or wear before each use and replace the tool if edge integrity is compromised.
