Sgs 33470 Corner Radius End Mill 0.5in 3 Flute Carbide

Product Description

The SGS 33470 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining applications. It features a 0.5-inch cutting diameter, a 0.03-inch corner radius, and three right-hand spiral flutes with a coarse pitch configuration. The 38-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiB2 (titanium diboride) coating increases surface hardness and reduces friction, extending tool life in demanding ferrous and non-ferrous machining environments. This is a centercutting tool, meaning it can plunge directly into workpiece material. It is a Series 43 tool in the SGS lineup and is intended for use by machinists and CNC operators in job shop and production settings.

The SGS 33470 is suited for finish milling, contouring, and slotting operations where a small corner radius is required to reduce stress concentrations at part features. The 2.5-inch length of cut provides adequate reach for moderate-depth pocket milling and side milling passes. With a 0.5-inch shank diameter, it mounts directly in standard ER or side-lock toolholders commonly found on vertical machining centers and CNC mills. The right-hand cutting direction is standard for conventional CNC milling setups.

Key Features

• 0.03-inch corner radius reduces stress risers and improves surface finish at part edges
• TiB2 coating increases hardness and lowers cutting friction for extended tool life
• 38-degree helix angle promotes efficient chip evacuation during deep cuts
• Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Three-flute design balances chip clearance and rigidity for steel and aluminum milling
• Solid carbide construction provides rigidity and dimensional stability at elevated cutting speeds

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 0.5-inch shank toolholding systems on CNC vertical machining centers and manual mills.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the machine in a powered-off and locked-out state per applicable machine safety procedures. Ensure the shank is fully seated and clamped to the minimum recommended engagement depth for the toolholder type in use. Inspect the cutting edges for chips or damage before each use. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut.
