Helical Solutions 03345 Square End Mill 3/8 in 3 Flute

Product Description

The HELICAL SOLUTIONS 03345 is a 3-flute, single-end square end mill ground from solid carbide and engineered for cutting aluminum and other non-ferrous materials. The cutter runs a 3/8-inch diameter with a 1-inch length of cut and a 45-degree helix angle, which promotes aggressive chip evacuation and reduces built-up edge common when machining aluminum. Overall length is 3 inches with a straight cylindrical 3/8-inch shank. The uncoated bright finish is intentional for aluminum applications, where certain coatings can cause material adhesion. This tool is installed by machinists and CNC operators in job shops, aerospace shops, and general manufacturing environments.

This end mill is suited for milling aluminum, aluminum alloys, and similar soft non-ferrous materials in both roughing and finishing passes where chip flow and surface finish are priorities. The 3-flute geometry balances flute volume for chip clearance against the number of cutting edges, making it well matched to higher-speed aluminum operations on CNC machining centers and manual mills. The single-end configuration is standard for toolholders using straight-shank collets or end mill holders.

Key Features

• 3/8-inch cutting diameter with 1-inch length of cut for standard depth slotting and profiling
• 45-degree helix angle promotes efficient chip evacuation in aluminum
• 3-flute geometry balances chip clearance and cutting edge contact
• Solid carbide construction provides rigidity and wear resistance
• Bright uncoated finish optimized for aluminum to prevent material adhesion
• Right-hand cut, right-hand flute, centercutting design allows plunge entry

Compatibility

Part of the HELICAL SOLUTIONS End Mills for Aluminum series, 3-Flute Square 45-degree Helix. Designed for use in standard straight-shank collet chucks and end mill holders accepting a 3/8-inch shank diameter.

Installation Notes

Installation is performed by a machinist or CNC operator. Secure the shank fully in a collet or end mill holder to the recommended gauge-line depth and verify runout before cutting. Confirm spindle speed and feed rate are appropriate for the workpiece material and cut depth before starting the program. Inspect the cutting edges for chips or damage before each use and replace the tool if edge integrity is compromised.
