Overview

The Minerallac Company SKU 45432 is a 7-piece High-Speed Steel (HSS) hex shank drill set designed for efficient metalworking. This set includes fractional drill sizes from 1/16" to 1/4" (1/16", 3/32", 1/8", 5/32", 3/16", 7/32", and 1/4"), covering common applications in metal fabrication, HVAC, electrical, and general contracting. The drills feature a 135° split point geometry, which eliminates the need for pilot holes by self-centering and reducing walking, enabling faster penetration and cleaner starts on harder materials like stainless steel and high-carbon steel. The hex shank design ensures a secure grip in impact drivers and quick-change chucks, preventing slippage and maximizing power transfer for consistent performance. For quick bit changes without a drill chuck, pair these drills with Minerallac’s Quick-Change Drill Adapter (#39020). Made in the USA from durable HSS, these drills are built to withstand high temperatures and maintain sharpness, making them ideal for professional and industrial use. The polished flutes facilitate fast chip removal, reducing heat buildup and extending tool life.
