Sgs 36129 Roughing End Mill 1 in 5 Flute Solid Carbide Tin

Product Description

The SGS 36129 is a single-end roughing end mill engineered for aggressive material removal in milling applications. Built from micrograin solid carbide and coated with TiN, it delivers the hardness and surface protection needed for high-volume roughing passes. The 1 inch diameter tool features 5 flutes with a chipbreaker geometry and a 0.06 inch corner radius, which reduces cutting forces and improves chip evacuation during heavy cuts. A 30-degree maximum helix angle supports efficient chip flow. Machinists and tool-and-die professionals working with steel, cast iron, and similar materials rely on tools like this for fast stock removal before finishing passes.

This end mill suits CNC machining centers and manual mills used in job shops, production floors, and maintenance-and-repair operations. It is appropriate for roughing applications in ferrous and non-ferrous metals where coarse pitch geometry is preferred. The chipbreaker design is particularly useful in deep-cavity work and side-milling operations where chip packing is a concern. The straight-cylindrical shank fits standard ER collets and end mill holders with a 1 inch bore.

Key Features

• Micrograin solid carbide construction for hardness and wear resistance
• TiN coating for improved surface lubricity and tool life in ferrous materials
• Chipbreaker geometry reduces cutting forces and prevents chip packing
• 5-flute coarse pitch design balances feed rate capacity with chip clearance
• 0.06 inch corner radius reduces edge chipping at the cutting perimeter
• Right-hand cut and right-hand spiral flute configuration
• Center-cutting capable for plunge entry

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for 1 inch straight-cylindrical shank tool holders including ER collet chucks and end mill holders rated for 1 inch bore diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a calibrated torque wrench when tightening collet nuts to holder manufacturer specifications. Verify runout with a dial indicator after installation before engaging the workpiece.
