Harvey Tool 75101-C3 Tapered Ball End Mill 15 Deg Altin

Product Description

The HARVEY TOOL 75101-C3 is a solid carbide tapered ball end mill engineered for precision contouring, mold work, and detail machining in tight geometries. It features a 15-degree taper angle per side and a 0.0400-inch small end diameter with a 0.0200-inch nose radius, making it well suited for fine-detail passes in hardened materials. The 2-flute design promotes chip evacuation in confined cuts, and the AlTiN coating extends tool life in high-temperature cutting environments. With a 0.1760-inch length of cut and 1.5-inch overall length, this mill is sized for controlled reaches without sacrificing rigidity.

This tapered end mill is used in CNC machining centers for die and mold applications, fine engraving, deep-cavity profiling, and core and cavity work where a standard straight end mill cannot reach angled walls. The ball end geometry produces smooth 3D surface finishes on contoured features. It fits into standard 1/8-inch collet or toolholder setups and is appropriate for both ferrous and non-ferrous materials where the AlTiN coating provides thermal resistance. Machinists in toolrooms, mold shops, and precision job shops are the primary users.

Key Features

• 15-degree taper angle per side for controlled wall-draft geometry
• 0.0400-inch small end diameter with 0.0200-inch nose radius for fine detail work
• AlTiN coating provides heat and wear resistance in hard-material cutting
• 2-flute solid carbide construction for rigidity and sharp edge retention
• 12-degree helix angle optimized for smooth chip flow in tapered cuts
• Runner Cutter series geometry designed for consistent performance in mold and die work

Compatibility

Designed as an OEM-style replacement or direct-use tool for CNC machining setups requiring a 1/8-inch shank tapered ball end mill with 15-degree taper per side geometry.

Installation Notes

Installation is performed by a CNC machinist or toolroom operator. Secure the 1/8-inch shank in a matching precision collet or end mill holder and torque to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as excessive runout on small-diameter end mills accelerates wear and risks tool breakage. Confirm spindle speed and feed rates against your CAM program and material data before engaging the cut.
