Seco 00029138 Tapered End Mill 6.50mm 3 Flute Solid Carbide

Product Description

The SECO 00029138 is a solid carbide tapered end mill designed for precision milling operations where a controlled taper profile is required. It features a 15-degree taper angle per side, a 6.50 mm small end diameter, and a 25.00 mm length of cut. The three-flute, right-hand spiral configuration provides efficient chip evacuation and a stable cutting action. With a bright, uncoated finish and a 30-degree helix angle, this tool is suited for applications where coating is not required or where base carbide performance is preferred. It is installed and operated by machinists and tooling professionals in CNC machining environments.

This end mill is used in CNC milling centers for producing tapered slots, mold cavities, draft angles, and contoured surfaces. The 20.00 mm shank diameter and 90.00 mm overall length make it compatible with standard toolholders in mid-to-large machining setups. It is non-centercutting and should not be used for plunge cutting. Primary workpiece material categories include cast iron (K), stainless steel (M), non-ferrous materials (N), steel (P), and high-temperature alloys (S), with non-ferrous materials listed as a secondary focus.

Key Features

• 6.50 mm small end diameter with a tolerance of +0.1/0 mm
• Three right-hand spiral flutes with a 30-degree helix angle for efficient chip removal
• Solid carbide construction for rigidity and wear resistance
• Bright/uncoated finish suitable for a wide range of base-material applications
• 20.00 mm shank diameter with h5 tolerance for precise toolholder fit

Compatibility

Designed for use with standard toolholders accepting a 20.00 mm shank diameter. Suitable for workpiece materials classified under primary codes K, M, N, P, and S, which correspond to cast iron, stainless steel, non-ferrous metals, steel, and high-temperature alloys respectively. Part of the SECO HK series.

Installation Notes

This tool should be installed by qualified machinists following the toolholder manufacturer's clamping specifications. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout with a dial indicator before cutting; the maximum TIR for this tool is specified at 0.0008 inches. This end mill is not centercutting and must not be used for direct plunge operations.
