The Inner Hole Has 45 Bevel Angles on Both Sides. After The Knife is Pulled Down, and Outer Type Alloy BB
This disposable internal bore chamfer cutter features precision 45° cutting geometry paired with SD carbide B45 inserts, purpose-built for bidirectional 45° chamfering on both front and back edges of inner bores. Compatible with standard CNC lathes, it completes chamfering and deburring in one pass to boost machining efficiency.
The indexable insert design removes the need for time-consuming regrinding, allowing fast insert replacement with minimal production downtime. The SD carbide B45 grade delivers sharp cutting edges and outstanding wear resistance, ensuring consistent chamfer dimensions and smooth, burr-free finished surfaces across carbon steel, alloy steel and stainless steel.
Widely used in precision machinery, hardware components and mold manufacturing, this chamfer tool boasts a rigid tool shank for stable cutting performance. It effectively lowers per-piece tooling cost and reduces machine idle time, providing a cost-effective solution for high-volume internal bore chamfering operations.
