Sgs 38505 Roughing End Mill 3/8 in 5 Flute Solid Carbide

Product Description

The SGS 38505 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from micrograin solid carbide with an AlTiN coating, it delivers durability and heat resistance in demanding cutting environments. The 3/8-inch diameter cutter features 5 spiral flutes with a variable pitch and a 37-degree medium helix angle, which reduces chatter and vibration during heavy roughing passes. With a 1/2-inch length of cut and a 2.5-inch overall length, this tool is suited for pocketing, slotting, and peripheral milling operations. Installation and use are handled by machinists and CNC operators in job shop and production settings.

This end mill is well-suited for use in CNC machining centers and manual milling machines where high material removal rates are required. The right-hand flute direction and right-hand cutting direction make it compatible with standard spindle configurations. The straight-cylindrical shank provides reliable tool holding in collet chucks and end mill holders. It is commonly used in ferrous and non-ferrous metalworking applications where chip evacuation and surface finish control during roughing operations are priorities.

Key Features

• Micrograin solid carbide construction for wear resistance and rigidity
• AlTiN coating provides thermal protection and extended tool life in dry or semi-dry cutting
• 5-flute variable pitch design reduces harmonic vibration during roughing passes
• 37-degree medium helix angle promotes efficient chip flow
• Right-hand cut, right-hand spiral configuration for standard spindle setups
• Straight-cylindrical shank with h6 tolerance for precise tool holding

Compatibility

Designed as an OEM-style replacement and standard-fitment roughing end mill for use in collet chucks, end mill holders, and shrink-fit holders accepting a 3/8-inch straight-cylindrical shank in CNC and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing tooling. Ensure the shank is fully seated and torqued to the tool holder manufacturer's specifications before operation. Verify spindle direction matches the right-hand cutting configuration of this tool before running.
