Sgs 46851 Corner Radius End Mill 3mm 4 Flute Solid Carbide

Product Description

The SGS 46851 is a solid carbide corner radius end mill designed for high-performance metal removal in demanding machining environments. Built to the ZPMC series specification, it features a 3 mm mill diameter, an 8 mm length of cut, and a 0.30 mm corner radius that reduces stress concentration at the cutting edge and extends tool life. The TX coating improves wear resistance and thermal stability, making this end mill well suited for aggressive material removal as well as finishing passes. A 6 mm straight-cylindrical shank seats securely in standard end mill toolholders. The 4-flute, variable-helix, variable-index geometry suppresses chatter and improves surface finish. Installed by machinists and tool-and-die professionals in CNC milling operations.

The SGS 46851 targets steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Its micrograin carbide substrate and TX coating handle the elevated cutting temperatures and abrasive conditions common when milling these workpiece families. The single-end, right-hand cutting and right-hand flute direction make it compatible with conventional CNC vertical and horizontal machining centers using standard end mill toolholders. The variable helix and variable index angles reduce harmonic vibration during long-reach cuts and interrupted cuts alike, supporting both roughing and finishing strategies in a single tool.

Key Features

• Solid micrograin carbide substrate for strength and wear resistance in ferrous and superalloy materials
• TX coating provides thermal and abrasion resistance for extended tool life
• Variable helix (35 to 38 degrees) and variable index geometry minimize chatter and vibration
• 0.30 mm corner radius reduces edge chipping and improves corner strength
• 4-flute configuration balances chip evacuation with rigidity for combined roughing and finishing
• Straight-cylindrical shank with h6 tolerance for precise toolholder fit

Compatibility

Designed for use with standard end mill toolholders. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium; secondary application includes hard materials. Compatible with CNC machining centers that accept a 6 mm straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer torque and runout specifications. Confirm shank seating depth and runout with a dial indicator before operation. Do not exceed the toolholder manufacturer's recommended clamping torque. Ensure the spindle and toolholder are clean and free of chips or debris before seating the shank.
