Seco 10268354 Square End Mill 1in 4-flute Carbide

Product Description

The SECO 10268354 is a 1-inch diameter, 4-flute solid carbide square end mill designed for high-performance milling in demanding shop and production environments. Built from micrograin carbide and coated with SIRON-A, this tool delivers extended tool life and wear resistance when cutting steel, stainless steel, cast iron, and high-temperature alloys. The 30-degree right-hand helical flute geometry promotes efficient chip evacuation and smooth cutting action. With a 1.5-inch length of cut and a 4-inch overall length, it fits standard short-reach roughing and finishing applications. Licensed machinists and CNC programmers working on ferrous and exotic workpiece materials will find this an appropriate production-grade option.

This end mill suits single-end milling operations in vertical and horizontal machining centers as well as manual knee mills. It is particularly effective in applications involving steel (P-code), stainless steel (M-code), cast iron (K-code), and high-temperature alloys (S-code) per ISO material classification. The straight-cylindrical shank accommodates standard collet chucks and end mill holders sized for 1-inch bore toolholding. The centercutting geometry allows plunge milling in addition to peripheral and slot milling operations.

Key Features

• 1-inch mill diameter with a matching 1-inch straight-cylindrical shank for rigid toolholding
• Micrograin solid carbide substrate for hardness and wear resistance in ferrous materials
• SIRON-A coating reduces friction and extends tool life in steel and stainless steel cutting
• 4 right-hand helical flutes at 30 degrees for efficient chip flow and surface finish
• Centercutting design enables plunge entry without a pre-drilled hole
• 1.5-inch length of cut with 4-inch overall length suits short-reach production milling

Compatibility

Designed for use in standard 1-inch bore end mill holders, collet chucks, and shrink-fit toolholders on CNC machining centers and manual mills. Primary workpiece material compatibility includes steel, stainless steel, cast iron, and high-temperature alloys as designated by ISO material codes P, M, K, and S.

Installation Notes

Installation should be performed by a qualified machinist following machine tool manufacturer guidelines. Ensure the spindle is fully stopped and locked before mounting or removing the end mill from the toolholder. Verify that the toolholder bore and collet size match the 1-inch shank diameter before clamping. Confirm runout does not exceed the 0.0005-inch TIR maximum specification after installation to maintain cut quality and tool life.
