Precision in
Tight Spaces
Custom-engineered gear-driven solutions for aerospace & automotive since 1973
Engineered for the Impossible
THE CLEARANCE PROBLEM
Standard tools can't reach fasteners in confined aerospace assemblies. Our gear-driven offset design accesses spaces where straight-line tools fail.
THE DURABILITY GAP
Cast housings crack under repeated high-torque cycles. Brimatco's uni-body design machines each housing from a single solid block — zero weld points, zero failure seams.
SEAMLESS INTEGRATION
Universal compatibility with Ingersoll Rand, Atlas Copco, Chicago Pneumatic, and all major pneumatic platforms. Drop-in, zero-downtime deployment.
Built Different,
Since 1973
Uni-Body Design
Every housing is precision-machined from a solid billet of hardened steel. No casting, no welding, no weak points. This is the foundation of Brimatco's legendary durability — a single, seamless structure engineered for decades of service.
The B-Series Archive
Every custom tool Brimatco builds is assigned a unique B-Series part number and archived for life. Need an exact replacement 15 years from now? One call, one part number, delivered.
In-House Heat Treating
Our metallurgists control the entire hardening process — carburizing, quenching, tempering — under one roof. No outsourced guesswork. Precise Rockwell hardness for every application.
Duty Class Catalog
Six precision-graded duty classes engineered for every torque requirement — from delicate avionics to mission-critical structural applications.
QCL Series
Ideal for delicate avionics fasteners and precision electronics assembly where controlled, low-torque application is critical.
