Rotary tool accessory for metalworking, promising precise cutting and longer tool life, EZARC Tungsten Carbide Burr SB-5. Tradespeople and keen home mechanics will appreciate reduced vibration and smoother finishes when shaping hardened metals. Will the extended lifespan over HSS make the change worthwhile for everyday workshop use?
⚡ At a Glance
- • Cutting Quality: Clean, quick cuts through hardened steel with smoother surfaces and less dust than grinding wheels
- • Best for: Metalworkers and engineers needing precise material removal on hardened steels and cast components
- • Not ideal for: Aluminium work, as aluminium is not recommended
YG-6 tungsten carbide burr in a double-cut cylinder end shape with a 1/4-inch shank. Hardness up to HRC70 and suitable for use with rotary and machine tools when clamped concentrically.
Longer Tool Life - thanks to YG-6 tungsten carbide
YG-6 tungsten carbide reaches hardness levels up to HRC70, and is stated to last up to ten times longer than HSS in comparable tasks. The higher hardness resists wear when cutting hardened steels.
Less frequent replacements reduce downtime in busy workshops and make heavy use more economical over time.
Cleaner, Faster Material Removal - with double cut design
Solid double cut flutes break material into smaller chips, cutting quickly through hardened steel while producing less dust than grinding wheels or single-cut cutters. The pattern yields a smoother surface on contact areas.
Faster stock removal and a neater finish minimise time spent on filing and polishing after shaping.
Stable, Controlled Operation - with 1/4-inch shank and cylinder end cut
A 1/4-inch shank fits electric and rotary tools as well as machine tool spindles, and the cylinder with end cut allows both side and end-face work. Proper clamping and concentric alignment are required to avoid vibration.
Predictable handling and minimal vibration support accurate profiling and fine deburring when mounted correctly.

❓ Frequently Asked Questions
Q: Which metals can this burr be used on?
A: Suitable metals include cast iron, cast steel, carbon steel, alloy steel, stainless steel and quenched steel; aluminium is not recommended.
Q: What tools are compatible with the shank?
A: A 1/4-inch shank works with electric rotary tools and can be installed on machine tools, provided the shank is clamped and aligned without shaking.
Q: How does durability compare with high-speed steel (HSS)?
A: Made from YG-6 tungsten carbide, the burr is said to last up to ten times longer than HSS and reaches hardness up to HRC70.
🏆 Our Verdict
Ideal for tradespeople and serious hobbyists who need reliable, precise removal from hardened metals. YG-6 tungsten carbide combined with a double-cut cylinder end design delivers long life and cleaner, faster cuts. While initial outlay may be higher than basic cutters, the extended durability and reduced finishing time deliver better value over the long term.
