Harvey Tool 834211-C3 Square End Mill 11/64 in 4 Flute Carbide

Product Description

The HARVEY TOOL 834211-C3 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It carries an 11/64 inch (0.1719 inch) cutting diameter with a 7/8 inch length of cut and a 3-inch overall length. The 4-flute, right-hand cutting geometry paired with a 30-degree helix angle supports efficient chip evacuation and stable cutting performance. An AlTiN coating increases surface hardness and thermal resistance, extending tool life in high-temperature cutting environments. This end mill is centercutting, allowing plunge entry. It is a single-end tool intended for use in CNC machining centers and manual mills by machinists and tooling professionals.

This end mill fits applications requiring tight-tolerance profiling, slotting, and peripheral milling in steel, stainless steel, cast iron, and similar materials. The AlTiN coating makes it well-suited for dry or minimal-lubrication cutting conditions where heat buildup is a concern. The 3/16 inch shank diameter fits standard collets and toolholders in that bore size. No extended reach geometry is present, keeping the tool compact for close-clearance work in dies, molds, and fixture components.

Key Features

• 11/64 inch (0.1719 inch) cutting diameter for small-feature milling
• 4 flutes with right-hand cut and right-hand flute direction for stable material removal
• 30-degree helix angle supports chip flow and reduces cutting forces
• AlTiN coating for elevated hardness and heat resistance in demanding cuts
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Solid carbide construction provides rigidity and wear resistance over high-speed tool steel alternatives

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 3/16 inch shank collet or toolholder.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the collet to the recommended engagement depth before tightening to prevent runout. Do not exceed the tool manufacturer's recommended speeds and feeds for the coating and material combination.
