Overview

The Minerallac Company 9/64" Trinado Heavy-Duty Drill Bit (SKU: 33309) is a precision-engineered straight shank drill bit designed for demanding metalworking applications. Constructed from M7 industrial steel, this drill bit delivers superior heat resistance and edge retention, outperforming standard HSS bits in high-temperature environments. The black and bronze oxide surface treatment reduces friction and wear, extending tool life by up to 30% compared to uncoated bits. Featuring a 135-degree split point, this bit offers exceptional self-centering capabilities, eliminating the need for a center punch and preventing bit 'walking' on hard metals. It excels in drilling stainless steel, high-carbon steels, and other tough alloys with minimal chatter and burr formation. The straight shank design ensures compatibility with standard drill chucks and magnetic bases, making it ideal for use in drill presses, milling machines, and handheld drills. Key applications include metal fabrication, machining, construction, and industrial maintenance where precision and durability are critical. Each drill bit is manufactured in the USA and backed by Minerallac's reputation for quality tooling. Available in a 12-piece pack for bulk efficiency.
