Hertel 750417 Square End Mill 3/8 in 3 Flute Solid Carbide

Product Description

The HERTEL 750417 is a solid carbide square end mill designed for general-purpose and finish milling operations on a variety of workpiece materials. It features a 3/8 inch cutting diameter, a 7/8 inch length of cut, and a 3-flute geometry with a 30-degree helix angle. The AlTiN coating improves heat resistance and extends tool life in dry or semi-dry cutting conditions. Micrograin carbide construction provides hardness and edge integrity under demanding cutting loads. This end mill is center-cutting, allowing it to plunge directly into a workpiece. It is suited for use in CNC machining centers and manual milling machines operated by machinists and toolroom technicians.

This end mill is appropriate for slotting, profiling, and pocket milling in ferrous and non-ferrous materials where a single-end, right-hand cut tool is required. The 3/8 inch shank diameter fits standard collets and end mill holders common in both production and job-shop environments. The 2-1/2 inch overall length provides a compact, rigid setup suitable for shallow to medium-depth features. It is sold individually and is well suited for maintenance machining, prototype work, and production runs where consistent chip evacuation and surface finish are priorities.

Key Features

• 3/8 inch cutting diameter with matching 3/8 inch shank for direct collet fitment
• Solid micrograin carbide construction for hardness and wear resistance
• AlTiN finish for elevated heat resistance in dry and semi-dry cutting
• 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Center-cutting geometry allows direct plunge entry without pre-drilling
• Right-hand cut, single-end design with no chipbreaker or variable helix

Compatibility

Designed as a direct-fit replacement or standard tooling option for any milling setup accepting a 3/8 inch straight shank end mill in an ER collet, end mill holder, or equivalent toolholder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Minimum stick-out should be used to maximize rigidity and minimize deflection. Verify collet condition and holder cleanliness before clamping to maintain concentricity.
