Product Overview

Upper and Lower chamfering cutter​ (commonly known as a bright-finish back boring tool, double-angle chamfer milling cutter, or dovetail cutter). It is engineered for precision machining operations, including front and back chamfering, back-edge deburring, and specialized angular slotting. Featuring an uncoated design, this tool maintains an extremely sharp cutting edge, making it the ideal choice for non-ferrous metals and soft materials.

Key Features & Advantages

Ultra-Sharp Cutting Edge (Bright Finish): The uncoated, polished silver surface eliminates the edge-rounding/dulling effect often caused by coatings. This preserves maximum sharpness, reduces cutting forces, and effectively prevents material adhesion (built-up edge).

Premium Solid Carbide Substrate: Manufactured from high-grade micrograin/ultrafinegrain solid carbide (tungsten steel), delivering exceptional hardness and bending resistance for stable operation at high spindle speeds.

Mirrored Flutes & Superior Finish: The precision-ground flutes feature a mirror-like finish and optimized clearance, allowing chips to evacuate rapidly while achieving an excellent surface finish on the workpiece.

Extended Neck Clearance: The reduced-neck design allows the tool to reach safely into deep holes or confined pockets, enabling back-machining that standard tools cannot perform.

Typical Applications

Machining Operations: Back chamfering and deburring of through-holes (without the need to flip or re-setup the workpiece), dovetail slotting, and V-groove milling.

Best Suited Materials:

Aluminum Alloys (Pure aluminum, die-cast aluminum, aircraft aluminum, etc.)

Copper & Copper Alloys (Brass, bronze, copper, etc.)

Engineering Plastics (Acrylic, POM/Delrin, PC, Nylon, etc.)

Other free-machining non-ferrous materials.
