Dual-Face Shearing
The two angled cutting faces shear both sides of a V profile during the same pass.

Double Angle Shank Cutters
What Are Double Angle Shank Cutters and How Do They Work?
A double angle cutter is a form-milling tool with a pointed or flat-tipped V profile on a cylindrical shank. Its two opposing angular faces cut internal and external V profiles, chamfers, thread forms, and serrations without reorienting the tool.
V-Grooving and Threading
Linear or helical toolpaths produce 60°, 90°, or custom angular grooves and thread forms.
Deburring and Chamfering
The upper and lower faces can bevel top and underside edges of workpiece steps in one setup.
Rigid Shank Drive
A solid cylindrical shank supports concentric mounting in standard CNC chucks and collets.
Key Features and Benefits of Double Angle Shank Cutters
Dual-Edge Cutting
Cuts both sides of an angular profile together to reduce the number of machining passes.
Single-Setup Chamfering
Bevels top and bottom slot edges without flipping the workpiece.
Ground Angular Form
Ground profile geometry supports repeatable angular dimensions across production runs.
Solid Shank Stiffness
The solid shank helps limit chatter and deflection during angular slotting.
Multiple Flute Options
Available with 3, 4, 6, or 8 flutes to suit chip-load and feed requirements.

Materials and Coatings Available for Double Angle Shank Cutters
| Material / Coating | Best For | Key Advantage |
|---|---|---|
| Solid Carbide | Hardened steels, stainless steel, titanium, and cast iron. | Core rigidity helps limit deflection during V-slotting operations. |
| TiAlN / AlTiN Coating | Tough alloy steels, high-temperature metals, and dry milling. | Thermal stability helps protect V-point cutting lips from friction-related wear. |
| DLC / CrN Coating | Aluminum, brass, copper, and non-ferrous alloys. | Low friction helps reduce material welding and built-up edge on angular flutes. |
Solid carbide supports rigid angular cutting, TiAlN or AlTiN addresses high-temperature alloy applications, and DLC or CrN helps reduce adhesion in non-ferrous materials.
Which Machines Use Double Angle Shank Cutters?
CNC Machining Centers
3-, 4-, and 5-axis centers run V-grooving, thread-milling, and chamfering operations.
Swiss-Type CNC Lathes
Live-tooling stations machine thread forms, cross features, and serrations on turned parts.
Horizontal Milling Machines
Use these cutters for V-track and serration-plate milling.
Applications and Industries for Double Angle Shank Cutters
Thread Milling and Profiling
Machines large-pitch internal and external thread profiles in alloy components.
V-Slot Milling and Indexing
Cuts 60° and 90° positioning notches, spline teeth, and serration tracks.
Top and Bottom Edge Chamfering
Bevels top edges and underside shoulders of slots without a second fixture setup.
Medical and Dental Serration
Machines gripping teeth on surgical forceps and clamping fixtures.
Frequently Asked Questions About Double Angle Shank Cutters
How does a double angle cutter differ from a single angle cutter?
A single angle cutter has one angular cutting face. A double angle cutter has two converging faces, allowing it to cut both sides of a groove or opposing chamfers.
Can a double angle milling cutter be used for thread milling?
Yes. Cutters ground to a suitable included angle, such as 60° for common UNC, UNF, and metric thread forms, can mill threads on bores and external shafts.
How do I choose between a sharp and truncated tip?
Use a sharp V point for sharp-bottom grooves, fine serrations, or small thread roots. A truncated tip provides more material at the tip for clearance slots, shoulder chamfering, and heavier V-grooving.
Can these cutters perform underside deburring?
Yes. The lower angular face can pass through a slot or bore and cut upward to chamfer a bottom edge.
Can Bauron produce custom double angle shank cutters?
Bauron can review asymmetrical angles, web thicknesses, shank diameters, and coating requirements from manufacturing drawings.
