Engineered for Aerospace-Grade Accuracy and Finish
Aerospace machining requires more than just durability—it demands control, consistency, and a flawless finish. Spec Tool brings extensive experience in:
-
Custom boring bars for small-diameter and precision internal machining
-
Carbide cutting tools tailored for titanium, Inconel, and composite applications
-
HSS cutting tools for lighter metals with detailed geometries
-
Tool holders and CNC fixtures for complex aerospace assemblies
-
Surface finish optimization and edge prep for defect-free part production
Our ceramic cutting tools and CBN cutting tools are carefully selected based on application demands and designed for long-lasting performance in high-volume production.
For the highest performance in the toughest non-ferrous applications, we design and build PCD inserts and tooling. PCD tooling is essential in the aerospace industry, as many of the aluminum alloys respond very well to it.
Aerospace Cutting Tools Built to Spec
From first article to full production, we partner with aerospace manufacturers to develop cutting tools that meet tight tolerances and even tighter timelines. If you need a solution that delivers clean finishes, holds tolerance, and keeps production moving—we’re here to help.
