uxcell 17.5mm Drill Bit 12mm Reduced Shank 3-Flat M35 5% Cobalt High-Speed Steel Twist Nitriding Black 118° Bits for Hard Metal Stainless Steel,1pcs

Description

Product Overview

The uxcell 17.5mm drill bit is engineered for professionals and serious DIY enthusiasts who demand precision, durability, and performance from their tooling. Featuring a 12mm reduced shank, this bit fits a broad spectrum of cordless and corded drills, providing a secure, wobble‑free connection that maximizes torque transfer. Constructed from M35 high‑speed steel (HSS) alloyed with 5% cobalt, the bit offers superior hardness and heat resistance, allowing it to maintain a sharp cutting edge even under the intense friction of drilling hardened steels and alloys. A nitrided black finish further enhances surface hardness, reduces friction, and extends service life by protecting against corrosion and wear. The 118° split‑point tip is a proven geometry that reduces the need for pilot holes, delivering rapid chip evacuation and a clean, accurate entry point. Overall, this drill bit combines material science, thoughtful design, and practical dimensions to meet the rigorous demands of metalworking, construction, and maintenance tasks.

Usage

Designed for versatility, the uxcell 17.5mm drill bit excels in a variety of real‑world applications. Whether you are fabricating steel frames, repairing machinery, or installing hardware in stainless‑steel structures, this bit provides the cutting power needed to create precise holes quickly. Its reduced shank design makes it ideal for use with compact impact drivers and lightweight cordless drills, enabling users to work in confined spaces without sacrificing performance. The bit is also suitable for drilling into alloy cast iron, copper, aluminum alloys, and even non‑metallic materials such as high‑density plastics and hardwoods, making it a valuable addition to any multi‑material workshop. For optimal results, start with a smaller pilot hole when working with very hard materials, apply appropriate cutting fluid to reduce heat buildup, and maintain a steady feed rate. The bit’s robust construction tolerates high RPMs, but users should adhere to the recommended speed range for HSS tools to preserve edge integrity and prolong lifespan.

FAQ

What materials can this drill bit handle?

The bit is optimized for high‑hardness metals such as carbon steel, stainless steel, alloy cast iron, and copper. It also performs well on aluminum alloys, brass, plastics, and hardwoods.

Do I need to use coolant when drilling with this bit?

While the nitrided finish helps reduce heat, using a suitable cutting fluid or coolant is recommended for prolonged drilling of very hard metals to maintain edge sharpness and prevent overheating.

Can I use this bit in an impact driver?

Yes, the reduced 12mm shank is designed for impact drivers and compact cordless drills, allowing you to work in tight spaces without sacrificing performance.

How do I maintain the sharpness of the bit?

Periodically clean the cutting edges to remove metal chips, store the bit in a dry environment, and avoid excessive force or speeds beyond the recommended range for HSS tools.
