1/2 x 13 NC Toolant HSS Drill Bit – 10.9mm Diameter, 3-Flute Spiral

Description

Product Overview

The Toolant 1/2 x 13 NC drill bit is engineered from premium High Speed Steel (HSS), delivering exceptional hardness and heat resistance for demanding drilling operations. With a cutting diameter of 10.92 mm (approximately 10.9 mm) and a 135‑degree cutting angle, this bit cuts cleanly through alloy steel, stainless steel, and other hard materials. Its straight shank is sized for a 1/2‑inch (13 mm) chuck, ensuring a secure fit in most power drills and hand‑held rotary tools. The three‑flute spiral design provides optimal chip evacuation, reducing heat buildup and extending tool life. Uncoated for maximum material contact, the bit maintains a sharp cutting edge even after prolonged use. Packaged in a compact box measuring 5.98 × 2.05 × 0.83 inches and weighing just 5 oz, it is lightweight yet robust, making it ideal for both on‑site work and workshop environments.

Usage

This drill bit excels in a variety of professional and hobbyist applications. It is perfect for creating precise holes in automotive components, machinery housings, and metal fabrication projects where accuracy and surface finish are critical. The bit’s high‑speed steel composition allows it to handle high RPMs without losing sharpness, making it suitable for use in cordless drills, impact drivers, and bench‑mounted drill presses. Whether you are assembling a metal frame, installing hardware in a steel cabinet, or performing maintenance on industrial equipment, the 1/2 × 13 NC size provides the versatility needed for a wide range of hole diameters. Its durability also makes it a reliable choice for repetitive drilling tasks in production lines, where consistency and reduced tool changeover time are essential.

FAQ

What materials can this drill bit effectively drill?

The 1/2 × 13 NC HSS drill bit is designed for alloy steel, stainless steel, carbon steel, and other hard metals. Its high‑speed steel composition also performs well on cast iron and some hardened plastics, making it a versatile choice for many industrial and DIY projects.

Is the bit suitable for high‑speed cordless drills?

Yes, the bit’s HSS material and 135‑degree cutting angle allow it to operate at high RPMs typical of modern cordless drills. The straight shank ensures a secure grip in the chuck, minimizing wobble and delivering consistent results even at elevated speeds.

How does the three‑flute design improve drilling performance?

The three‑flute spiral design creates larger clearance channels for chips to exit the cutting zone quickly. This reduces friction, lowers operating temperature, and helps maintain a sharp cutting edge, resulting in smoother cuts and longer tool life.

Can I use this bit for repeated production drilling?

Absolutely. The bit’s durability and heat‑resistant properties make it well‑suited for repetitive drilling in production environments. Its ability to retain sharpness over many cycles reduces downtime caused by frequent tool changes.
