Norseman 44170 Ultra Dex Drill Bit Set — 29-Piece, 135° Split Point, Premium HSS

Meet the Norseman 44170 Ultra Dex Drill Bit Set

Designed for professionals who demand precision and longevity, the 29-piece Norseman Ultra Dex kit combines premium high-speed steel with a specialized Hi-Molybdenum alloy and a durable gold oxide finish. This combination is chosen to withstand demanding drilling tasks while preserving edge life and accuracy.

135-Degree Split Point for clean starts

The bits feature a 135-degree split point that initiates holes with minimal wandering, helping you maintain true alignment as you begin cutting into metal, wood, or composite materials. The cut is designed to deliver accurate hole diameters with less effort wasted fighting drift and more consistent hole placement.

What’s inside the set

• 29 pieces covering sizes from 1/16 in to 1/2 in by 64ths
• Ultra Dex precision-ground point, flutes, body, clearance, and diameter for consistent performance
• Special Hi-Molybdenum tool steel with a gold oxide finish for wear resistance
• Built to NAS 907B-style consistency, emphasizing tight tolerances and reliable life

Why choose Norseman Ultra Dex for your shop

• Durable alloy and coating designed to handle challenging drilling tasks and repeated use
• Accurate hole sizes across a broad range helps you reduce rework
• Quality manufacturing focus translates into predictable, repeatable results

Real-world use cases

Ideal for fabrication, automotive, metalworking, and construction tasks where clean starts and steady diameters matter. The 29-piece set provides versatility for quick tool changes without searching for compatible bits.

Note: While results depend on material and technique, the Ultra Dex line is built to support robust performance in everyday machining scenarios.

Quality you can rely on

Norseman emphasizes control and consistency across production. Each component undergoes precision grinding and inspection to ensure the cutting edge meets tight tolerances. The Hi-Molybdenum alloy contributes to wear resistance, while the gold oxide finish reduces surface wear and helps maintain coating integrity over time.

Practical considerations

To maximize performance, pair these bits with appropriate feeds and speeds for the material you drill, keep the bits sharp, and use proper clamping to avoid deflection. The 135-degree split point helps reduce the need for starting marks and improves overall hole quality when drilling tough materials.

In the toolkit

Compact, versatile, and ready for a professional shop, the 29-piece set covers common hole sizes for a wide range of jobs, from quick metal fabrication to cabinet making and automotive work.
