Seco 74034245 Chamfer Milling Tip 0.315 in Carbide

Product Description

The SECO 74034245 is a replaceable chamfer milling tip engineered for the Minimaster MM08 interchangeable-head milling system. Manufactured from solid carbide with a TiAlN coating applied via PVD process, this right-hand tip carries a 45-degree chamfer angle and a 90-degree included angle. It cuts at a diameter of 0.315 inches and delivers a maximum depth of cut of 0.149 inches. The T60M grade and M03 chipbreaker geometry are matched to a wide range of workpiece materials, making this tip a reliable choice for precision chamfering and centering operations across production environments.

This tip fits the Minimaster MM08 series tooling system and is suited for use on CNC machining centers in both shop-floor and production settings. Its two-flute geometry and 0.374-inch functional length are sized for compact, high-precision work. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Machinists and tooling specialists use this tip for chamfering, center-drilling, and countersinking applications where repeatable, consistent geometry is critical.

Compatibility

Designed as a direct-fit replaceable tip for the Minimaster MM08 series milling system, insert size 0.315-C90. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials (ISO material codes P, M, K, N, S, H).

Installation Notes

Installation of replaceable milling tips should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before changing tips. Seat the tip firmly in the MM08 holder and torque the clamping screw according to the holder manufacturer specifications. Inspect the seating surface for chips or debris before each installation to maintain runout accuracy.
