Engineering Specifications

Detailed Reamer Classification & Hangar Application

Match your specific airframe substrate, clearance envelope, and fastener fit requirement to the appropriate reamer configuration.

HSS Piloted Chucking Reamer
Piloted Alignment

HSS Piloted Chucking Reamers

Featuring an integral front pilot diameter that guides the cutter into the existing hole, eliminating concentricity errors, chatter, and bell-mouthing. Standard straight-shank geometry ensures compatibility with portable drill chucks and stationary shop machinery. Ideal for multi-layer 2024/7075 aluminium skin repairs.
HSS Threaded Shank Piloted Reamer
NAS 965 Type D

HSS Threaded Shank Piloted Reamers

Designed with standard 1/4-28 threaded shanks for direct attachment to pneumatic right-angle motors and microstop units. The integral pilot keeps the cutter centered in tight-clearance wing ribs, fuselage frames, and internal structural compartments where straight drills cannot fit.
Solid Carbide Chucking Reamers
Abrasive Alloys & CFRP

Solid Carbide Chucking Reamers

Built for extreme heat resistance and long tool life when reaming Titanium (Ti-6Al-4V), Inconel®, stainless steels, and carbon fiber composite stacks. Solid carbide holds ultra-tight diameter tolerances and provides superior surface micro-finishes required for critical structural certification.
Master Reamer Sets
Tool Crib Solutions

Precision HSS Straight Reamer Sets

Complete master sets formatted specifically for aerospace tool cribs and repair depots. Available in 29-piece fractional (1/16" to 1/2" by 64ths), 60-piece wire gauge (#1 to #60), and 26-piece letter (A to Z) sets. All sets are organized in heavy-duty fitted metal cases for rapid size identification and inventory control.

Material-to-Reamer Selection & Operational Parameters

Engineering parameters for hand-held pneumatic and CNC machine reaming across common aerospace alloys and composite materials.

Recommended speed, feed, and tool geometry selection for precision aerospace hole reaming.
Airframe Material Recommended Tool Substrate Flute / Shank Configuration Operational Parameters & Best Practices
2024-T3 / 7075-T6 Aluminium High-Speed Steel (HSS) / M42 Cobalt Straight Flute, Piloted Chucking High surface speeds with steady manual or automatic feed. Use light cutting oil or mist lubricant to flush aluminum chips and maintain micro-finish.
Titanium Alloys (Ti-6Al-4V) Solid Carbide / M42 Cobalt Straight or Spiral Flute Run at 1/3 to 1/2 drilling RPM with constant positive feed pressure. Do not dwell or allow cutter to idle; use flood coolant to prevent work hardening.
Inconel® & Stainless Steels (17-4PH, 300/400) Solid Carbide / Premium Cobalt Heavy-Duty Straight Flute Low surface speeds (20–30 SFM), high rigidity setup. Ensure pilot is properly lubricated to avoid galling inside the hole prior to reaming.
Carbon Fiber Composite (CFRP) Solid Carbide Specialized Composite Flute Geometry High RPM, moderate feed rate. Sharp carbide cutting edges prevent delamination and fiber pull-out at exit. Dust extraction strongly recommended.
Hi-Lok® & NAS Fastener Holes HSS / Solid Carbide Piloted 1/4-28 Threaded Shank or Straight Shank Ream hole to within +0.0015" / -0.0000" tolerance. Verify finished diameter with pin gauges before seating precision structural pins.

Technical FAQ

Aerospace Reamer Selection & Application FAQs

Why are piloted chucking reamers preferred for aircraft structural assembly?
Piloted chucking reamers feature a precision-ground pilot guide preceding the multi-flute cutting edges. This ensures perfect axial alignment with pre-drilled pilot holes in multi-layer aircraft sheet metal or composite-metal stacks, preventing hole angularity, chatter, and bell-mouthing during fastener preparation.
When should aerospace engineers specify solid carbide over HSS or M42 cobalt reamers?
Solid carbide reamers are recommended for high-volume aerostructure production, abrasive carbon-fiber-reinforced polymers (CFRP), titanium Ti-6Al-4V, and heat-treated nickel alloys. Carbide retains extreme cutting-edge sharpness, extends tool life, and maintains tight hole diameter tolerances across long production runs.
Are your threaded shank reamers compatible with standard aerospace angle drive motors?
Yes. Pan American Tool threaded shank reamers are manufactured with standard 1/4-28 threads, fully conforming to NAS 965 Type D specifications for seamless integration with right-angle pneumatic drill motors, offset attachments, and microstop cages.
Can I order aerospace reamers in custom sizes or M42 cobalt material?
Yes. In addition to our comprehensive stock of High-Speed Steel (HSS) reamers, we supply M42 cobalt reamers and custom fractional/decimal sizes upon request to solve unique airframe repair challenges.
