Seco 00029133 Tapered End Mill 3 Flute Solid Carbide

Product Description

The SECO 00029133 is a solid carbide tapered end mill designed for precision material removal in demanding machining applications. Built to Series HK specifications, this tool features a 3-flute, right-hand spiral configuration with a square end geometry and a 15-degree taper angle per side. The small end diameter measures 0.2559 inches (6.50 mm), with a length of cut of 0.3937 inches (10.00 mm) and an overall length of 65.00 mm. The uncoated carbide construction provides rigidity and dimensional stability across a range of workpiece materials. Installation and use are suited to machinists and CNC operators working in production or tool-room environments.

This tapered end mill is rated for use across multiple workpiece material categories, including cast iron (K), stainless steel (M), non-ferrous materials (N), steel (P), and heat-resistant superalloys (S), with a secondary rating for non-ferrous (N) materials. The 12.00 mm shank diameter with an h5 tolerance shank fits standard collet and end mill holder systems. The 30-degree helix angle supports chip evacuation during spiral milling operations. This tool is not center-cutting and does not support coolant-through delivery, so application planning should account for these constraints.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• 15-degree taper angle per side for precise draft and angled wall machining
• 3-flute, right-hand spiral geometry with a 30-degree helix angle
• Square end profile for flat-bottom and shoulder milling operations
• Uncoated finish suited to non-ferrous and superalloy workpiece materials
• Small end diameter tolerance of +0.1/0 mm and TIR maximum of 0.0008 inches for dimensional accuracy

Compatibility

Rated for workpiece material codes K, M, N, P, and S, covering cast iron, stainless steel, non-ferrous metals, steel, and heat-resistant superalloys. Fits standard 12.00 mm end mill holders and collet systems with an h5 shank tolerance.

Installation Notes

This tool is intended for use by trained machinists operating CNC or manual milling equipment. Ensure the tool holder is clean and properly torqued to the machine spindle before operation. This end mill is not center-cutting and should not be plunged axially into the workpiece. Verify spindle speed and feed rate against the material being cut and the manufacturer cutting data recommendations before starting the operation.
