Helical Solutions 59282 Corner Radius End Mill 1/4 in 6 Flute

Product Description

The HELICAL SOLUTIONS 59282 is a solid carbide corner radius end mill engineered for high-performance milling in ferrous and difficult-to-machine materials. It runs a 1/4 inch mill diameter with a 0.0600 inch corner radius, a 3/8 inch length of cut, and a 2 inch overall length. The six-flute geometry with variable pitch and APLUS PVD coating supports both roughing and finishing operations in a single tool, reducing tool changes on the floor. Centercutting capability allows plunge entry. The HEV-6 series is built for use with high-precision toolholders to maximize runout control and surface finish consistency.

This end mill is suited for CNC machining centers running steel, cast iron, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials. The stub length type and straight-cylindrical shank make it a practical choice for close-tolerance work where rigidity matters. Primary application targets include low-alloy steel, medium alloy steel, tool steel, and cast iron. Secondary applications extend to stainless steel, non-ferrous metals, superalloys, and titanium. It is a single-end, right-hand cut, right-hand flute tool with no chipbreaker and no coolant-through capability.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• APLUS PVD coating extends tool life in steel, cast iron, and titanium applications
• Six-flute variable-pitch design reduces chatter and supports both roughing and finishing
• 0.0600 inch corner radius with tight tolerance of -0.0020 to 0.0020 inches
• Centercutting geometry allows direct plunge entry without a pilot hole
• Designed for use with high-precision toolholders; maximum TIR 0.0005 inches

Compatibility

Designed for use with high-precision toolholders. Suitable for CNC machining applications in steel, cast iron, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials as specified for the HEV-6 series.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle at a full stop and machine in a locked-out state per shop safety protocol. Use a high-precision toolholder matched to a 1/4 inch straight-cylindrical shank to maintain runout within the specified TIR of 0.0005 inches. Confirm proper seating depth and torque per the toolholder manufacturer specifications before resuming operation. Do not exceed recommended cutting parameters for the target workpiece material.
