Hertel 750143 Square End Mill 1/32 in 2 Flute Solid Carbide

Product Description

The HERTEL 750143 is a square end mill designed for precision milling in tight-tolerance applications. Built from micrograin solid carbide, it delivers the hardness and wear resistance needed for cutting ferrous and non-ferrous materials at small scales. The cutter measures 0.0313 inches (1/32 inch) in diameter with a 3/32 inch length of cut and a 1/8 inch shank diameter. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. Centercutting geometry allows plunge milling in addition to peripheral and slot cuts. This tool is sold as a single-end, uncoated carbide end mill intended for CNC machining centers and manual mills.

This end mill is suited for fine detail work, micro-slot milling, and small-feature contouring in die and mold work, electronics enclosures, and prototype machining. The 1/8 inch shank is a common collet size found in standard ER and precision collet chucks. The 1-1/2 inch overall length keeps the tool rigid at this small diameter, minimizing deflection during cut. Applications typically include light profiling and pocketing passes in aluminum, brass, mild steel, and plastics where a very small cutter diameter is required.

Key Features

• Micrograin solid carbide construction for hardness and edge retention at small diameters
• 0.0313 inch (1/32 inch) cutting diameter for fine-detail and micro-feature work
• Centercutting design enables direct plunge entry without a pre-drilled hole
• 30-degree helix angle promotes chip flow and reduces cutting forces
• Right-hand cut, right-hand flute configuration for standard spindle rotation
• 2-flute geometry balances chip clearance and core strength at this diameter

Compatibility

Designed as a direct-fit replacement for standard 1/8 inch shank collet chucks on CNC machining centers, manual knee mills, and precision die-sinking equipment requiring a 1/32 inch square end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Power down and lock out the spindle before changing tooling. Seat the 1/8 inch shank fully and evenly in a clean, undamaged collet to the recommended engagement depth before torquing the collet nut. At this small diameter, tool runout must be minimized — inspect the collet and chuck for wear before use, as even minor runout accelerates breakage on cutters this size.
