Seco 17016432 Square End Mill 3/4 in 4 Flute Cobalt Ticn

Product Description

The SECO 17016432 is a single-end, 4-flute square end mill engineered for material removal in demanding metalworking applications. Built from M42 cobalt high-speed steel and finished with a TiCN (Titanium Carbonitride) coating, it handles elevated cutting temperatures and abrasive workpieces better than standard HSS tooling. The cutter measures 0.750 inches in diameter with a 2.000-inch length of cut and a 4.250-inch overall length. A 30-degree right-hand spiral helix promotes efficient chip evacuation and smooth cutting action. This tool is center-cutting, allowing direct plunge entry. It is suited for CNC machining centers and manual mills operated by machinists and toolroom technicians.

The 17016432 is designed for use in metalworking environments where steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys are the primary workpiece materials. The TiCN coating extends tool life when cutting abrasive materials. A 3/4-inch shank diameter fits standard collet chucks and end mill holders common on vertical machining centers and knee mills. This tool belongs to the SECO SPC408 series, which targets general-purpose and production milling across job shops and manufacturing facilities.

Key Features

• M42 cobalt steel construction provides hardness and heat resistance beyond standard M2 HSS
• TiCN coating reduces friction and wear on abrasive workpiece materials
• 30-degree right-hand helix promotes efficient chip flow and reduces cutting forces
• Center-cutting geometry allows direct plunge milling without a pre-drilled pilot hole
• Single-end design with 4 flutes balances surface finish quality with material removal rate
• Mill diameter tolerance of +0.0000 to -0.0030 inches ensures consistent fit in close-tolerance setups

Compatibility

Part of the SECO SPC408 series. Compatible with standard 3/4-inch collet chucks and end mill holders. Rated for steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys (ISO material codes P, M, K, N, S).

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the spindle is fully stopped and the machine is powered down before mounting or removing the end mill. Seat the shank fully in the holder to the recommended engagement depth and torque the set screw or collet nut per the holder manufacturer's specification. Inspect runout with a dial indicator before cutting — TIR maximum for this tool is 0.0010 inches.
