Description
SJ-5M Countersink 60° Carbide Rotary Burr - High Alloy Steel Processing

This SJ 60-degree countersink burr is designed specifically for chamfering and deburring operations on high-alloy steels. Its unique 60-degree pattern maintains cutting sharpness while enhancing edge strength, making it particularly suitable for high-precision chamfering of difficult-to-machine materials such as stainless steel and tool steel. The optimized flute design and wear-resistant coating effectively suppress work hardening and built-up edge formation, providing fast, clean, and consistent chamfer quality in aerospace, automotive, and precision machinery manufacturing.

Primary Cutting Geometries

1. Single-Cut

Single-cut rotary burrs feature parallel lines of teeth running diagonally across the cutting face in only one direction. This configuration is particularly suitable for processing soft non-ferrous metals, plastics, soft high-tensile steel, and hard wood. The single-cut pattern has a larger rake angle and larger chip clearance, making it less prone to chip clogging and ensuring efficient cutting on softer materials.

2. Double-Cut

Double-cut (or cross-cut) burrs feature two interlaced groups of cutting teeth that intersect each other. This pattern is more aggressive for material removal and produces less vibration during operation. Double-cut burrs are ideal for high cutting performance on hard materials such as cast iron, cast steel, and glass fiber plastic materials. They provide excellent surface processing quality with relatively high machining efficiency.
