Seco 02970126 Ball End Mill 2 Flute Solid Carbide 3 Mm

Product Description

The SECO 02970126 is a solid carbide ball end mill designed for precision milling in demanding machining environments. Built to Series JH112 specifications, this single-end tool features a 3 mm mill diameter with a 1.5 mm nose radius, a 6 mm straight-cylindrical shank, and an overall length of 60 mm. The HXT PVD coating provides thermal resistance and wear protection, making this end mill well-suited for cutting cast iron and hard materials. Micrograin carbide construction supports consistent performance at tight tolerances, with a mill diameter tolerance of 0.01/0.00 mm and a maximum TIR of 0.01 mm.

This end mill is used in CNC milling operations requiring extended reach into cavities, pockets, and contoured surfaces. The extended-reach neck geometry, with a 3 mm neck length and 2.80 mm neck diameter, allows access to features that standard-length tools cannot reach. It is suited for both roughing and finishing passes on cast iron and hard workpiece materials. Machinists and toolroom operators in production and job-shop environments will find this tool effective for tight-tolerance profiling work.

Key Features

• 3 mm ball end mill diameter with 1.5 mm nose radius for contour and profile milling
• HXT PVD coating for wear resistance in cast iron and hard material applications
• Extended-reach design with 6 mm reach length and 2.80 mm neck diameter
• 2-flute, right-hand cut, right-hand helical flute geometry at 28-degree helix angle
• Micrograin solid carbide substrate for dimensional stability and edge retention
• Single-end configuration; no coolant-through; straight-cylindrical shank with h5 tolerance

Compatibility

Designed as an OEM-style replacement and standard tooling selection for CNC machining centers and milling machines accepting a 6 mm straight shank. Compatible applications include milling of cast iron and hard materials per primary workpiece material codes K and H. Manufacturer catalog number JH112030G3B.0Z2-HXT.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully powered down and locked out before changing tooling. Verify shank seating and runout with a dial indicator before cutting; the maximum allowable TIR for this tool is 0.01 mm. Use a collet or toolholder rated for the 6 mm shank diameter and confirm clamping torque per the toolholder manufacturer's specifications.
