Helical Solutions 29600 Corner Radius End Mill 3/4 in 3 Flute

Product Description

The HELICAL SOLUTIONS 29600 is a solid carbide corner radius end mill designed for high-efficiency material removal in aluminum and non-ferrous metal applications. It features a 3/4 inch mill diameter, a 2-1/4 inch length of cut, and a 0.0300 inch corner radius, making it well suited for roughing operations where edge strength and chip clearance matter. The 3-flute geometry with a 45-degree high helix angle promotes fast evacuation of soft, sticky chips common in aluminum. At 5 inches overall length with a 3/4 inch straight-cylindrical shank, the tool fits standard high-precision toolholders and delivers consistent runout within a 0.0003 inch TIR maximum.

This end mill is built for CNC machining environments where aluminum and non-ferrous metals are the primary workpiece materials. It is also rated for secondary use in steel, stainless steel, cast iron, high temperature alloys, and hard materials, giving shops flexibility across job types. The coarse pitch, right-hand flute direction, and centercutting capability allow it to plunge, slot, and profile in a single tool. Series H45AL-C-3 identifies it within the HELICAL SOLUTIONS roughing lineup for non-ferrous applications.

Key Features

• 3/4 inch diameter with h6 mill diameter tolerance for accurate fit in precision toolholders
• 0.0300 inch corner radius with a tight tolerance of -0.0020 to 0.0020 inch for consistent edge geometry
• 3-flute, 45-degree high helix design optimized for aluminum and non-ferrous roughing
• Centercutting geometry supports plunging and ramping operations
• Bright/uncoated finish — no coating buildup, ideal for aluminum where coatings can cause material adhesion
• Chipbreaker included to segment chips and reduce re-cutting in long-cut applications
• Maximum TIR of 0.0003 inch supports use with high-precision toolholders

Compatibility

Designed for use with high-precision toolholders. Primary workpiece material is aluminum and non-ferrous metals; secondary compatibility includes steel, stainless steel, cast iron, high temperature alloys, and hard materials. Series H45AL-C-3.

Installation Notes

Installation is performed by CNC machinists or tool-and-die professionals. Seat the 3/4 inch straight-cylindrical shank fully in a clean, undamaged collet or toolholder bore and torque to the toolholder manufacturer specification. Confirm runout with a dial indicator before beginning a cut, as the 0.0003 inch TIR maximum requires a properly maintained toolholder. Do not exceed the recommended speeds and feeds for the workpiece material, and ensure the spindle and fixture are fully secured before engaging the cut.
