What It Is

This threaded shank aircraft drill bit is manufactured from premium M42 cobalt high speed steel, a high-performance tool steel known for exceptional heat resistance, hardness, and wear life in demanding metal drilling applications. Designed for use in compatible threaded drill systems, these bits are commonly used in aerospace, aviation maintenance, fabrication, and industrial environments where precision and durability are critical.

The threaded shank configuration provides a secure mechanical connection that helps improve drilling stability and control compared to conventional straight shank drill bits.

What Makes It Different

Unlike standard general-purpose drill bits, these aircraft drills are built for demanding metalworking applications where secure retention, accuracy, and heat resistance matter. The 135° split point geometry allows the drill to begin cutting quickly upon contact with the material, helping reduce walking and improve hole placement accuracy.

Compared to conventional drill point designs, the split point geometry: Improves hole positioning accuracy Reduces walking at startup Requires less thrust pressure Increases drilling efficiency in hard metals The threaded shank design also provides positive engagement in compatible tooling systems, making these ideal for repetitive professional drilling applications.

Material & Performance Advantages

M42 cobalt high speed steel offers significantly greater heat resistance and wear performance than standard high speed steel, making it a preferred material for tough metal drilling applications.

This makes these drill bits especially well suited for:

• Stainless steel
• Hardened steel
• Tool steel
• Cast iron
• High-strength alloys
• General metal fabrication materials

Aircraft & Precision Drilling Applications

Threaded shank aircraft drills are commonly used in professional applications where secure fitment, precision hole placement, and dependable performance are essential. They are ideal for: Aircraft manufacturing and maintenance Aerospace assembly work Industrial fabrication Metalworking operations Repair and maintenance environments Production drilling applications Their combination of cobalt durability, split point accuracy, and secure threaded retention makes them a trusted choice for professional metal drilling.
