Super Turbo Chamfer Mills


Seco Tools has announced a new line of Super Turbo chamfer mills designed to provide high metal removal rates while reducing production costs. The new cutters use the same inserts and hardware as standard Super Turbo square shoulder mills, allowing manufacturers to increase the versatility of their operations without additional spare parts.

The new Super Turbo chamfer mills feature a high positive cutting rake angle and positive helix angle to reduce power consumption, resulting in freer cutting and reduced harmonics. The design increases tool life as compared to standard APxx style cutters, helping to reduce cost per part.

The new chamfer mills use the same strong insert pocket design found in the rest of the Super Turbo family of products. The strong insert screws and thick, robust inserts offer increased reliability for fewer tooling changes.

Super Turbo chamfer mills are available in setting angles of 30°, 45°, 60° and 75°, with a depth of cut capability of 0.197” – 1.653”, for production of the most common open or close to shoulder chamfers. The new tools are available in Seco-Capto™ and Combimaster® back-end options, with standard shell mill mounting styles in either inch or metric arbor holes. All versions include internal coolant channels.

As part of the Super Turbo mill family, the chamfer mills utilize the full range of Super Turbo insert grades, including Duratomic® coatings, and geometries. This ensures that the tools apply across a wide range of materials and applications.

Seco Tools’ Turbo Mill offering is a comprehensive and versatile square shoulder milling product line that provides solutions for slotting, ramping, contouring, plunging, pocket milling and both circular and helical interpolation. The family offers a choice of 13 carbide grades, 3 PCD-tipped grades and 5 geometries suited for a variety of materials, including steel, stainless steel, cast iron, hardened materials, high-temperature alloys and non-ferrous materials. Super Turbo’s unique inserts feature an optimized edge, advanced helix angle, large wiper flat and strong, highly positive rake angle to allow high productivity.
