BECOLLO 17/32-inch Cobalt Drill Bit, 1/2-inch Reduced Shank with 3 Flats, 2-Pack

Overview

Meet the BECOLLO 17/32-inch cobalt drill bit set—a compact, two-piece solution designed for demanding metals and precise starts. Crafted from cobalt-enhanced high-speed steel (5% cobalt), these bits deliver improved wear and heat resistance, helping you maintain sharp cutting edges across real-world tasks without interrupting your workflow.

Whether you’re tackling stainless steel, cast iron, or other metals, this pair is built to stay steady under pressure. The 1/2-inch reduced shank and three flats provide a more secure grip in your chuck, supporting consistent, controlled drilling from start to finish.

Key benefits

• Wear and heat resistance extended by cobalt alloy, promoting longer bit life under tough conditions.
• 135-degree split point design for fast cutting and easy self-centering, reducing wandering on hard workpieces.
• 1/2-inch reduced shank with 3 flats offers a firmer, more reliable chuck grip.
• Specially suited for drilling in stainless steel and cast iron; softer materials are also feasible.

Ideal applications

• Machining hard metals where precision starts and minimal walk-off matter.
• DIY and professional tasks involving stainless steel, cast iron, and similar alloys.
• Any setup where a compact, portable two-piece cobalt drill bit set is advantageous.

What’s included

• Two cobalt drill bits, 17/32-inch each
• Plastic storage case for easy organization and transport

In everyday use, you might notice smoother starts, fewer interruptions to re-align the drill, and steadier progress when piercing harder metals. The combination of cobalt’s strength, a precise split point, and a secure shank design can translate into a more efficient workflow without guaranteeing specific results.
