AMAMCO Tool

What AMAMCO Tool does

AMAMCO Tool is a privately held U.S. manufacturer of custom precision carbide cutting tools, founded in 1972 and headquartered in Lyman, South Carolina. The company designs and produces application-specific drills, reamers, composite routers, drill/countersinks, PCD tools, and precision reamers for the aerospace, composites, automotive, energy, and industrial manufacturing sectors. Its core technology stack rests on solid carbide substrates, polycrystalline diamond (PCD), CVD diamond coatings, and brazed-tip constructions, combined with proprietary geometries such as the Double Margin Drill, Compression Router, Three Stage Reamer, and Slow Spiral Router — engineered to prevent delamination, extend tool life, and meet tight hole tolerances in advanced composite and metallic stacks.

The business operates a sales-led, consultative go-to-market model in which AMAMCO's tool engineers and master tool grinders collaborate directly with customer engineers to design tools specific to each application. Pricing is quote-based and not publicly disclosed, with tools sold predominantly as one-time purchases plus an attached reconditioning service that extends tool life and reinforces customer relationships. Distribution is primarily direct (toll-free and local phone, online quote request) with selective channel partnerships — most notably with Brunswick Tooling for precision reamers. The company holds ISO 9001:2015 registration (since 1996) and AS9100D aerospace certification (since 2003), and serves named tier-1 customers including Boeing, Lockheed Martin, Spirit AeroSystems, Gulfstream, and Airbus, with documented program wins on the F-35 (via NCDMM-validated compression router) and Boeing 787 (Three Stage Reamer). AMAMCO is reported to be the sole manufacturer of Double Margin Drill on many aerospace applications, reflecting a niche sole-supplier position in a small but defensible segment of the precision tooling market.

Products and services

• Double Margin Drill Precision carbide drill with double margin (four-margin) construction designed for close tolerance holes in single pass operations; ideal for Advanced Drilling Units (ADUs).
• Drill Reamer Single tool that combines drilling and reaming functions in one operation, with two or four flute reaming step configuration for close-tolerance holes, high-quality surface finish, and reduced exit burrs.
• Drill/Drill Reamer Double margin construction with a second drilling step to share chip load and a final reaming step for close tolerance holes in diverse materials and stacks.
• Double Margin Slow Spiral Drill Advanced point geometries for titanium applications with a slower spiral helix that reduces aggressiveness and four margins for stability in close tolerance holes.
• Compression Router Solid carbide router with opposing geometries that compress composite layers to prevent delamination in advanced composite materials with tight tolerances; approved for the F-35 Joint Strike Fighter program.
• Slow Spiral Router High-speed CNC composite routing tool with reduced flute helix that cleanly shears composite fibers with minimal vertical force to prevent delamination; used for Boeing, Lockheed, Gulfstream, and Airbus aircraft programs.
• Diamond Cut Router Composite routing tool used for satellite and rocket manufacturers, suitable for hand routing, CNC, and robotic applications with customizable flute geometries.
• Special Purpose Router Versatile composite tool functioning as rougher or finish router with multiple flutes to prevent vibration and shallow left flutes to prevent delamination.
• KC Router Composite router developed for cutting thick or thin composites, Kevlar, or fiberglass with serrated edge design and CVD diamond coating for extended tool life.
• Piloted Step Reamer Precision reamer with exacting geometries for composite, titanium, aluminum, or stack applications and customizable geometry from end to end.
• Two Step Reamer Reamer recommended for composites, hand applications, and metal/composite stacks, producing excellent holes with little or no exit burr.
• Three Stage Reamer Reamer developed for the Boeing 787 program to produce close tolerance holes in composite and composite stacks such as CFRP/titanium, eliminating delamination with lower transition angles.
• Composite Drills Specialized drills for aerospace manufacturers working with advanced materials prone to delamination, fiber breakout, and uncut fibers; combines custom geometries with advanced diamond coatings.
• Drill Countersink Single cutting tool that performs three functions in one pass—drill, ream, and countersink—accommodating complexities of torque increase and special material demands.
• Application-Specific Tools Custom tools designed specifically for customer processes, combining understanding of application process with mastery of cutting tool geometries and grinding principles.
• Precision Reamers Custom, application-specific precision reamers offered in partnership with Brunswick Tooling, featuring carbide cutting tips brazed onto high-speed steel shank for extended-run applications.
• PCD Tools Custom, application-specific PCD (Polycrystalline Diamond) tools providing durable cutting surfaces for precision cuts in high-performance materials such as aluminum and carbon composites.
• Ready-to-Ship Tools Popular innovative tool designs manufactured and warehoused for quick delivery, including extended flute versions for thick complex composites.
• Reconditioning Tool restoration service using the same craftsmen and precision machines to restore tools to new condition, extending tool life and maximizing the number of reconditions.
