Overview

The Minerallac Company 91605D is a 1/8" High-Speed Steel (HSS) Jobber Drill designed for general-purpose drilling in metal applications. Manufactured in the USA, this drill features a standard 118° point angle, making it an economical choice for precise hole creation in mild steel, stainless steel, and other metals. The polished flute design ensures rapid chip removal, reducing heat buildup and extending tool life while delivering cleaner holes with minimal burrs. This 4-pack provides a convenient supply of identical drill bits, ideal for workshops, fabrication shops, and maintenance teams requiring consistent performance. Compatible with standard drill presses, handheld drills, and CNC machines, the 91605D is optimized for drilling speeds between 300-1200 RPM in ferrous metals. Its HSS construction resists wear and maintains sharpness longer than carbon steel drills, reducing replacement frequency and downtime. Common applications include metal fabrication, sheet metal work, repair tasks, and general maintenance. The 1/8" size is versatile for pilot holes, clearance holes, and small-diameter fasteners. Pair with Minerallac’s 118° Metal Index Set (SKU 91801) for a comprehensive drilling solution.
