Tungsten Carbide Rotary Burr SB-5 Double Cut 1/4″ Shank EZARC Tool

Description

Product Overview

The EZARC SB-5 tungsten carbide rotary burr is engineered for demanding metalworking tasks where precision, speed, and durability are essential. Constructed from YG6 grade tungsten carbide, the burr achieves a hardness of 90 HRA, ensuring that cutting edges stay sharp even under high‑speed conditions. Its double cut geometry provides two sets of cutting teeth, which accelerates material removal while minimizing chip buildup. The 1/4″ shank diameter matches the standard size for most die grinders, pneumatic tools, and rotary devices, allowing seamless integration into existing toolsets. With a total length of 2‑3/4″ and a cutter diameter of 1/2″, the burr offers a generous cutting surface while maintaining a compact profile for tight workspaces. The package includes a rugged storage case that protects the burrs from impact and contamination, extending their service life for professional use.

Usage

This double cut carbide burr excels in a wide range of applications across multiple industries. In automotive repair shops, technicians rely on the SB‑5 to deburr weld seams, chamfer edges, and polish engine components, achieving a clean finish without excessive heat buildup. Aerospace manufacturers use the burr for precision shaping of aluminum and titanium parts, where the high hardness of YG6 carbide prevents premature wear. Hobbyist metalworkers and fabricators benefit from the burr’s ability to quickly remove excess material from brackets, brackets, and custom fixtures, reducing overall project time. The tool operates efficiently at speeds between 25,000 and 50,000 RPM, making it suitable for both electric and pneumatic rotary tools. Proper cooling and occasional lubrication are recommended to maintain optimal performance and to prevent overheating during extended use.

FAQ

What materials can the SB‑5 burr safely work on?

The SB‑5 is suitable for a variety of metals including steel, stainless steel, aluminum, brass, copper, and titanium. Its carbide composition allows it to handle both ferrous and non‑ferrous alloys without significant dulling.

What is the recommended operating speed for optimal performance?

For best results, operate the burr within a speed range of 25,000 to 50,000 RPM. Staying within this range maximizes cutting efficiency while minimizing heat buildup.

How often should the burr be replaced or re‑sharpened?

Because the SB‑5 is made from high‑grade YG6 carbide, it typically retains its cutting edge for thousands of minutes of use. Replacement is only necessary when the cutting edges become visibly worn or when performance noticeably declines.

Can the burr be used with both electric and pneumatic tools?

Yes, the 1/4″ shank is compatible with most electric and pneumatic rotary tools that accept standard 1/4″ accessories, providing flexibility across different power sources.

Is there a warranty or guarantee for the product?
