Angular Shearing
Angled cutting lips shear material to form uniform 60°, 90°, or 120° included-angle chamfers.

Pointed Chamfer Cutters
What Are Pointed Chamfer Cutters and How Do They Work?
Pointed chamfer cutters are conical milling tools with a sharp, zero-radius tip. Unlike flat-end chamfer mills, the pointed geometry can enter small holes, tight internal corners, and narrow V-grooves.
Zero-Radius Point
The pointed tip reaches into small holes and tight recesses where a flat-bottom tool cannot fit.
Multi-Function Operation
One tool can perform top-edge chamfering, countersinking, 45° beveling, and fine V-carving.
Controlled Edge Finish
Polished flute margins are designed to limit burrs and chatter marks on the bevel.
Key Features and Benefits of Pointed Chamfer Cutters
Zero-Radius Tip Clearance
Reaches the bottom of tight internal angles and small-diameter bores.
Multi-Tasking Capability
Can replace separate deburring, countersinking, and engraving tools in suitable applications.
Edge Quality
Produces clean chamfer profiles and can reduce manual bench deburring.
High Rigidity
Solid carbide construction resists bending to support consistent chamfer width along long toolpaths.
Multiple Angle Geometries
Standard included angles of 60°, 90°, and 120° match different chamfer callouts.

Materials and Coatings Available for Pointed Chamfer Cutters
| Material / Coating | Best For | Key Advantage |
|---|---|---|
| Solid Carbide | Stainless steel, titanium, and high-temperature alloys. | Stiffness supports consistent chamfer widths. |
| TiAlN / AlTiN Coating | Hardened steels, cast iron, and dry milling. | Oxidation resistance protects the pointed tip from thermal wear. |
| DLC / ZrN Coating | Aluminum, copper, and non-ferrous materials. | Low friction helps prevent built-up edge on the chamfer flutes. |
Solid carbide provides rigidity, TiAlN or AlTiN supports harder materials and dry cutting, and DLC or ZrN helps reduce material buildup in non-ferrous applications.
Which Machines Use Pointed Chamfer Cutters?
3-Axis, 4-Axis, and 5-Axis CNC Mills
Integrate the cutters into automated deburring cycles for 2D and 3D contours.
Swiss-Type CNC Lathes
Use live tooling to deburr turned cross-holes and angled feature edges.
CNC Routers
Perform high-speed V-grooving, edge chamfering, and engraving in plastics and aluminum sheet.
Applications and Industries for Pointed Chamfer Cutters
Hole and Edge Deburring
Deburrs pre-drilled holes and sharp milled edges in automated CNC production.
Small-Hole Countersinking
Bevels small-diameter hole openings for flat-head screw seating.
V-Grooving and Engraving
Cuts serial numbers, alignment marks, and narrow fluid channels.
3D Edge Beveling
Follows contoured part perimeters to apply chamfers along angled 3D surfaces.
Frequently Asked Questions About Pointed Chamfer Cutters
How does a pointed chamfer cutter differ from a flat-end chamfer mill?
A pointed cutter ends in a zero-radius tip that can enter small holes and narrow internal corners. A flat-end chamfer mill has a non-zero tip diameter that improves tip strength for larger chamfers but limits access.
How do I calculate tool offsets for a pointed chamfer cutter?
Because surface speed at the exact point is zero, offset the toolpath so cutting occurs along the middle of the chamfer flute rather than at the extreme tip.
Can pointed chamfer cutters be used for V-carving or text engraving?
Yes. Their pointed tip and defined angle support serial numbers, logos, alignment marks, and narrow fluid-routing channels in metals and plastics.
Which included angle should I choose?
A 90° included angle cuts a 45° bevel and is commonly used for deburring. The source recommends 60° for tight-angle grooves or specified thread chamfers and 120° for shallow deburring and sheet-metal countersinking.
Does Bauron manufacture custom pointed chamfer cutters?
Bauron can manufacture non-standard included angles such as 82° or 100°, extended neck lengths, custom flute counts, and application-specific coatings.
