Sgs 37187 Roughing End Mill 3/8 in 5 Flute Solid Carbide

Product Description

The SGS 37187 is a single-end roughing end mill engineered for high-efficiency material removal in demanding machining applications. Built from micrograin solid carbide with an AlTiN coating, this tool delivers heat resistance and wear performance suited to hard materials and dry or near-dry cutting environments. The 3/8-inch diameter cutter features five flutes with a variable index geometry that disrupts harmonic chatter during aggressive cuts. Coolant-through capability supports flushing chips and managing heat at the cutting zone. This tool is installed and operated by machinists and tool-and-die professionals working on CNC machining centers and manual mills.

The SGS 37187 is designed for roughing passes in ferrous and non-ferrous metals where stock removal rate is the priority over surface finish. The 3/4-inch length of cut and 2-1/2-inch overall length make it well suited to shallow-to-moderate pocket depths in standard workpiece setups. The right-hand cutting and right-hand flute direction are compatible with conventional CNC spindle configurations. The straight-cylindrical shank with h6 tolerance ensures consistent tool holding in standard collet and end mill holders.

Key Features

• Micrograin solid carbide substrate for rigidity and edge retention
• AlTiN coating provides thermal resistance in high-speed and hard-material cutting
• Five-flute variable index design reduces chatter and improves surface stability during roughing
• Coolant-through construction supports chip evacuation and heat management at the cutting edge
• Right-hand cut, right-hand spiral flutes compatible with standard CNC spindle setups
• h6 shank tolerance for precise fit in collet chucks and end mill holders

Compatibility

Designed as an OEM-style replacement and standard-fit roughing end mill for CNC machining centers and manual mills accepting a 3/8-inch straight-cylindrical shank with h6 tolerance.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully powered down and locked out per facility lockout/tagout procedures. Seat the straight-cylindrical shank fully into the collet or end mill holder before torquing the retention hardware to the holder manufacturer specification. Confirm runout with a dial indicator before beginning cuts. This tool is not center-cutting — do not plunge directly into solid material; use ramping or helical entry instead.
