Harvey Tool 930631-C6 Ball End Mill 1/32 in 3 Flute Carbide

Product Description

The HARVEY TOOL 930631-C6 is a solid carbide ball end mill engineered for material removal in superalloys, titanium, and other high-temperature alloys. It features a 1/32 inch (0.0310 inch) mill diameter, a 5/32 inch length of cut, and a 34-degree variable helix angle that reduces harmonics and chatter during aggressive cuts. The AlTiN Nano PVD coating provides thermal resistance and hardness retention at elevated cutting temperatures. With three flutes and a right-hand cutting and flute direction, this tool is suited for finishing and roughing passes in difficult-to-machine aerospace and industrial materials. Installation and use require a CNC machining center or compatible toolholder with an 1/8 inch straight-cylindrical shank bore.

This end mill is designed for machining superalloys and titanium as its primary workpiece materials, with secondary suitability for steel, stainless steel, cast iron, and hard materials. It fits applications in aerospace component machining, medical device manufacturing, and precision die work where tight tolerances and tool life in heat-resistant alloys are critical. The long-length configuration and 5/32 inch reach length allow access in pockets and features where standard-length tools cannot reach. Single-end geometry means the tool is replaced rather than re-indexed when worn.

Key Features

• Variable helix angle at 34 degrees reduces chatter and improves surface finish in high-temp alloy cuts
• AlTiN Nano PVD coating provides thermal hardness and oxidation resistance for superalloy and titanium work
• Three-flute solid carbide construction balances chip evacuation and core strength at small diameters
• 0.0155 inch nose radius ball geometry enables contour milling and 3D surface work
• Long-length designation with 5/32 inch reach extends access into deep pockets and narrow features
• Right-hand cut and right-hand spiral; no coolant-through, no chipbreaker, straight-cylindrical shank

Compatibility

Designed for use in CNC machining centers and milling machines accepting a 1/8 inch straight-cylindrical shank. Primary workpiece materials are superalloys and titanium (ISO material code S); secondary materials include steel, stainless steel, cast iron, and hard materials (ISO codes P, M, K, H). Part of the HARVEY TOOL Variable Helix End Mills for High Temp Alloys - Ball series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank in a compatible collet or end mill holder to the appropriate clamping torque per the toolholder manufacturer's specification. Ensure the machine spindle is fully stopped and de-energized before tool changes. Do not exceed the tool's rated depth of cut or feed rates for the workpiece material being machined, as solid carbide tooling at small diameters is susceptible to breakage under excessive lateral load.
