Sgs 43535 Square End Mill 0.4724 in 3 Flute Solid Carbide

Product Description

The SGS 43535 is a solid carbide, single-end square end mill designed for precision milling in a wide range of metalworking applications. It features a 0.4724-inch (12 mm) cutting diameter with a matching 0.4724-inch straight-cylindrical shank, a 1.9685-inch (50 mm) length of cut, and a 100 mm overall length that places it in the extra-long category. The 3-flute configuration with a 30-degree right-hand spiral helix delivers efficient chip evacuation while maintaining rigidity. Micrograin carbide construction provides wear resistance across ferrous and non-ferrous workpiece materials. The bright, uncoated finish makes tool wear easy to monitor during production runs.

The SGS 43535 is suited for slotting, profiling, and peripheral milling operations in materials coded H, K, M, N, P, and S — covering cast iron, non-ferrous metals, stainless steel, carbon steel, and high-temperature alloys. The extra-long Series 5XLM geometry is commonly applied in deep-pocket milling and extended-reach applications where a standard-length end mill cannot reach the feature floor. It is a center-cutting tool, allowing direct plunge entry where required. Typical users include CNC machinists and toolroom technicians working on vertical and horizontal machining centers.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 3 flutes with 30-degree right-hand spiral helix for balanced chip flow
• Extra-long Series 5XLM geometry for deep-pocket and extended-reach cuts
• Center-cutting design permits direct plunge milling
• Bright, uncoated finish — no coating buildup to obscure wear patterns
• Straight-cylindrical shank for standard collet and end mill holder mounting

Compatibility

Designed for use in standard ER collets, end mill holders, or shrink-fit toolholders accepting a 12 mm (0.4724-inch) straight shank. Compatible with CNC machining centers and manual mills equipped for solid carbide tooling across material groups H, K, M, N, P, and S per the SGS Series 5XLM specification.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or removing the end mill. Verify holder runout is within the shank tolerance of +0.000 / -0.011 mm before cutting to avoid premature edge failure. Confirm toolpath programming accounts for the extra-long reach to prevent deflection and chatter on deep features.
