Hertel E299914052 Square End Mill 1 in 2 Flute Cobalt

Product Description

The HERTEL E299914052 is a single-end square end mill manufactured from M42 cobalt high-speed steel. It carries a 1 inch cutting diameter with a 1-5/8 inch length of cut and a 4-1/8 inch overall length. The 5/8 inch shank diameter is sized for standard milling chucks and collet holders. With a 30-degree helix angle and two right-hand spiral flutes, this tool is suited for general-purpose slot milling, profiling, and peripheral cutting in ferrous and non-ferrous materials. The bright, uncoated finish is appropriate for a wide range of shop applications. Licensed machinists and toolroom operators are the primary users.

This end mill is designed for use in vertical and horizontal milling machines as well as CNC machining centers where a 5/8 inch shank is compatible. It is centercutting, which allows plunge entry into workpiece material without a pre-drilled pilot hole. The 2-flute configuration provides good chip clearance, making it practical for slotting operations and softer materials where chip evacuation is a priority. The length of cut range of 1.5 to 2 inches accommodates moderate-depth passes in a single setup.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance compared to standard M2 HSS
• 30-degree right-hand helix angle promotes smooth cutting action and chip flow
• Centercutting design enables direct plunge milling without a pilot hole
• 2-flute spiral geometry maximizes chip clearance in slotting and deep-pocket cuts
• Bright, uncoated finish suitable for use with or without cutting fluid
• Single-end configuration with a 5/8 inch straight shank for broad holder compatibility

Compatibility

Designed as an OEM-style replacement or standard tooling selection for milling machines and CNC machining centers accepting a 5/8 inch straight shank end mill holder or collet.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and the machine locked out per applicable shop safety procedures. Confirm that the collet or end mill holder is rated for the 5/8 inch shank diameter before securing the tool. Tighten the holder to the machine spindle per the machine manufacturer's specifications. Inspect the cutting edges for chips or damage before each use and replace the tool if wear is evident.
