EZARC AlCrN Carbide Rotary Burr Bit (Pro), Double Cut Carbide Burr 1/4" Shank Die Grinder Cutting Burrs Bit for Hard Metal Working

All EZARC AlCrN Carbide Rotary Burr Bits (Pro) share the same size specifications: 2-3/4" total length, 1/4" shank diameter, 1/2" cutter diameter, and 1" cutting length. They are all engineered with a premium AlCrN coating for maximum durability and precision on hard metals. The main difference lies in the head shape, which determines their specific use cases:

SA-5 (Cylinder Shape, Flat End): Best for flat surface milling, slotting, and edge finishing.

SB-5 (Cylinder Shape with End Cut): Features cutting edges at the tip, allowing downward cutting—ideal for blind holes and end-face work.

SC-5 (Cylinder Shape, Round End): Rounded tip makes it perfect for contouring, chamfering, and smooth curve finishing.

SF-5 (Tree Shape, Radius End): Cone-shaped with a rounded end, designed for curved surfaces, inside corners, and narrow grooves.

SL-5 (Cylinder Shape, Long Neck with End Cut): Extended reach with end-cut edges, excellent for deep cavities and hard-to-reach areas.

AlCrN, Tough Coating

Made of high-hardness YG6 carbide (90 HRA), this rotary burr bit delivers reliable cutting performance and wear resistance. Now upgraded with an AlCrN coating, it offers significantly improved heat and abrasion resistance. Lab-tested to last up to 2X longer—engineered for professionals who demand performance in heavy-duty metalwork.

Double Cut Design

The extra cutting edges boost material removal speed, minimize loading, and leave smoother finish. The double-cut design offers greater control and precision for stable, accurate operation. Built to handle a wide range of materials—including tough metals like steel and cast iron.

Heavy-Duty Applications

This double-cut burr bit handles deburring, chamfering, engraving, polishing, and weld seam removal with ease. It’s built for demanding applications across industries like automotive, aerospace, metalworking, die and mold making, and more.

Master of Material Shaping

No dust pollution, stable, reliable and high efficiency. It is mainly used on electric and pneumatic tools, and the speed is generally 25000-50000 rpm. During use, it is essential to properly secure the tool, and utilize a reverse milling cutting method to prevent issues caused by reciprocating cuts.
