Sgs 36474 Corner Radius End Mill 1 in 4 Flute Carbide

Product Description

The SGS 36474 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. Built on the ZPCR series platform, it features a 1-inch cutting diameter, a 1.5-inch length of cut, and a 0.04-inch corner radius that reduces edge stress and extends tool life in both roughing and finishing passes. The variable helix geometry minimizes chatter and harmonics during aggressive cuts. An AlTiN (TX) coating provides thermal resistance and hardness at elevated cutting temperatures. With a 6-inch overall length and 4-inch reach, this tool is suited for deep-pocket and extended-reach applications requiring rigidity and surface consistency.

This end mill is intended for machining steel, stainless steel, cast iron, superalloys, and titanium, as well as hard materials. It performs in both roughing and finishing operations on CNC machining centers in job shop, production, and aerospace environments. The straight cylindrical shank is sized at 1 inch and is compatible with standard end mill holders. The single-end, right-hand cutting configuration with right-hand flute direction fits conventional CNC milling setups. The short-length-type classification and micrograin carbide substrate make it particularly effective in applications requiring tight tolerances and consistent surface finish on difficult-to-machine alloys.

Key Features

• Variable helix design reduces vibration and chatter during heavy cuts
• AlTiN (TX) coating improves heat resistance and wear life in ferrous and exotic alloys
• 0.04-inch corner radius distributes cutting forces and reduces chipping at the tool tip
• Micrograin solid carbide substrate maintains edge integrity in hard and abrasive materials
• 4-inch reach length supports deep-pocket machining without sacrificing rigidity
• Right-hand cut and right-hand helix with variable index for improved chip evacuation

Compatibility

Designed for use with standard end mill holders accepting a 1-inch straight cylindrical shank. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Compatible workpiece material codes: P, M, K, S, and H per ISO classification.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before installing or removing the end mill. Seat the shank fully in the holder to the manufacturer-recommended gauge length and torque the retention mechanism per the holder specification. Verify runout with a dial indicator before beginning a production cut, as excessive runout will accelerate edge wear and degrade surface finish.
