High-Performance NAS 965 Type D Adapter Drills
Pan American Tool proudly presents our highly efficient Type "D" threaded shank adapter drills, meticulously crafted from premium M42 cobalt high-speed steel and solid carbide to conform strictly with NAS 965 Type "D" aerospace specifications.
Featuring a 135-degree heavy-duty split point and specialized surface oxidation treatment, these adapter drills provide superior penetration and chip clearance when drilling high-tensile-strength aerospace alloys, titanium, Inconel®, and tough aluminum aircraft structures.
Compared to standard NAS 965 Type "B" high-speed steel adapter drills, our Type "D" cobalt and carbide series delivers significantly extended tool life. This durability yields a lower cost per hole, reducing maintenance downtime for airlines, MRO facilities, and OEM aerostructure assemblers worldwide.

NAS 965 Type D Dimensional & Overall Length Reference
Standard dimensions for 1/4-28 threaded shank drills across standard reach parameters. Always match bit selection with motor offset and work area clearance.
| Reach Designation | Shank Thread | Typical Flute Length | Overall Length Range | Primary Application |
|---|---|---|---|---|
| Very Stubby | 1/4-28 UNF-2A | 1/4" to 3/8" | 1" to 1-1/4" | Extreme tight-access structural repairs, minimal clearance angle motors. |
| Stubby | 1/4-28 UNF-2A | 1/2" to 5/8" | 1-1/4" to 1-1/2" | General wing rib, spar cap, and bulkhead drilling with 90° motors. |
| Short | 1/4-28 UNF-2A | 3/4" to 1" | 1-3/4" to 2-1/8" | Standard microstop countersink cage drilling and skin hole sizing. |
| Long | 1/4-28 UNF-2A | 1-1/4" to 1-1/2" | 2-1/2" to 3" | Deep pocket clearance and internal airframe structural assembly. |
| Extra Long | 1/4-28 UNF-2A | 1-3/4" to 2" | 3-1/2" to 6" | Extended-reach drilling through alignment jigs and multi-layer stacks. |
