uxcell 6.8mm Cobalt HSS Twist Drill Bit 2pcs Straight Shank for Metal

Description

Product Overview

The uxcell 6.8mm cobalt HSS twist drill bit is engineered for demanding drilling tasks across a variety of materials. Constructed from cobalt‑enhanced high speed steel, the bit delivers exceptional hardness, wear resistance, and toughness, ensuring a long service life even when confronting hardened metals such as stainless steel, cast iron, and tough alloys. The straight shank design provides a secure fit in standard power drill chucks, reducing wobble and improving accuracy during high‑speed operation. With a total length of 108mm and a flute length of 58mm, the bit offers ample reach while maintaining a compact profile suitable for tight workspaces. The full‑grinding process applied to the cutting edges creates a precise geometry that maximizes chip evacuation and minimizes heat buildup, resulting in smoother cuts and reduced tool wear. This combination of material quality, precise engineering, and thoughtful dimensions makes the uxcell 6.8mm drill bit a versatile solution for both professional machinists and dedicated DIY enthusiasts.

Usage

Designed for a broad spectrum of applications, this drill bit excels in environments where reliability and performance are paramount. In industrial settings, it is ideal for creating precise holes in hardened steel components, automotive parts, and aerospace assemblies where tolerance and surface finish are critical. For metalworking hobbyists, the bit provides the confidence to tackle copper, aluminum, and brass projects, delivering clean, burr‑free holes that require minimal post‑processing. Its ability to penetrate non‑ferrous metals as well as plastics makes it a valuable tool in electrical installations, where conduit and housing drilling often involve both metal and polymer materials. The straight shank ensures compatibility with most cordless and corded drills, allowing users to operate at variable speeds to match material hardness. Whether you are assembling a custom furniture piece, fabricating a prototype, or performing routine maintenance on machinery, the uxcell 6.8mm drill bit offers the flexibility and durability needed for consistent, high‑quality results.

FAQ

What materials can this 6.8mm drill bit effectively drill?

The bit is optimized for a wide range of materials, including hardened metals such as stainless steel and cast iron, as well as non‑ferrous metals like copper and aluminum. It also performs well on high‑strength plastics, making it suitable for mixed‑material projects.

How does the cobalt content improve drilling performance?

Cobalt adds hardness and heat resistance to the high speed steel matrix, allowing the bit to maintain a sharp cutting edge at higher temperatures. This results in faster drilling speeds, reduced wear, and a lower likelihood of tip breakage when working with tough alloys.

Can I use this drill bit in a standard cordless drill?

Yes. The straight shank is compatible with most 1/4‑inch and 3/8‑inch drill chucks found on both cordless and corded drills. Adjust the drill speed according to the material hardness for optimal results.

What is the recommended drilling speed for stainless steel?

For stainless steel, a slower speed of 500–800 RPM is advisable to minimize heat buildup. Use cutting fluid or lubricant to further reduce friction and extend the life of the cutting edge.

Is there a warranty or guarantee for this product?
