High-Precision 55 Degree Helix Angle Chamfering Cutter with Solid Carbide Substrate and Wear-Resistant Coating for Steel and Stainless Steel

Product Overview

Upper and Lower chamfering cutter (commonly referred to as a back boring tool, double-angle chamfer cutter, or dovetail cutter). It is primarily designed for precision machining operations such as chamfering, back boring, side slotting, and deburring. Its unique geometry makes it highly efficient for tackling challenging reverse hole features (like back-chamfering) or specific angled groove profiles.

Key Features & Advantages

Premium Solid Carbide Substrate: Made from high-grade solid carbide (tungsten steel) for exceptional rigidity, hardness, and bending resistance.

Advanced Wear-Resistant Coating: Finished with a heat-resistant and wear-resistant copper-colored coating (such as TiAlN or nano-composite), which effectively reduces cutting heat and significantly extends tool life.

Neck Clearance Design: Engineered with an extended neck clearance, allowing the tool to reach deep into holes or confined spaces for back-machining while avoiding mechanical interference.

Smooth Chip Evacuation: The optimized flute profile ensures excellent chip clearance during back-boring or chamfering, preventing chip packing and premature tool chipping.

Typical Applications

Back Chamfering & Deburring: Enables back-chamfering and deburring of thru-holes from the front side without flipping the workpiece, significantly reducing setup time and boosting productivity.

Dovetail & Angular Slotting: Well-suited for milling specific angled slots or profile grooves.

Applicable Materials: Widely applicable for machining carbon steel, alloy steel, mold steel, stainless steel, and non-ferrous metals like aluminum alloys.
