Helical Solutions 82230 Corner Radius End Mill 3/8in 6 Flute

Product Description

The HELICAL SOLUTIONS 82230 is a 6-flute solid carbide corner radius end mill designed for aggressive material removal in ferrous and high-temperature alloy applications. The cutter measures 3/8 inch in diameter with a 1-1/4 inch length of cut, a 3-inch overall length, and a 0.0300 inch corner radius that reduces stress concentration at the cutting edge and extends tool life. An APLUS PVD coating improves wear resistance and heat dissipation during high-speed milling. Variable pitch flute spacing reduces harmonic chatter, making this tool well-suited for demanding finishing and roughing operations in steel, cast iron, titanium, and superalloys.

This end mill is built for use in CNC machining centers where tight tolerances and surface finish quality are critical. It is particularly effective in shops running high-feed programs on low-alloy steel, medium alloy steel, tool steel, cast iron, and titanium workpieces. Secondary material suitability includes stainless steel and non-ferrous metals. The single-end, center-cutting configuration allows plunge entry and ramp-in toolpaths. High precision toolholders are recommended to maximize runout control and tool life. It fits standard 3/8 inch straight-cylindrical shank collets and milling chucks.

Key Features

• 6-flute geometry with variable pitch for chatter reduction during high material removal rate operations
• 0.0300 inch corner radius reduces edge chipping and improves part surface finish at corners
• APLUS PVD coating for enhanced wear resistance on steel, cast iron, superalloys, and titanium
• Solid carbide construction provides rigidity and dimensional stability under cutting loads
• Center-cutting and right-hand spiral fluting supports plunge, ramp, and contour toolpaths
• TIR maximum of 0.0005 inch ensures consistent dimensional accuracy across the cut

Compatibility

Designed for use with high precision toolholders. Fits standard 3/8 inch straight-cylindrical shank collets and milling chucks. Part of the HELICAL SOLUTIONS HEV-C-6 series.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and locked out per facility lockout/tagout procedures. Seat the shank fully into a clean, undamaged collet or milling chuck and torque the retention mechanism to toolholder manufacturer specifications. Inspect runout with a dial indicator before initiating cuts; excessive runout accelerates edge wear and can compromise part tolerance. Do not use worn or out-of-spec toolholders with this cutter.
