Zero-Radius Point Shearing
The sharp tip penetrates the workpiece surface to create very narrow line widths and dense text.

Pointed Engraving Cutters
What Are Pointed Engraving Cutters and How Do They Work?
Pointed engraving cutters are single-flute or multi-flute conical tools for fine surface marking and micro-milling. Their V-bottom geometry converges at a zero-radius or micro-flat tip that cuts narrow, high-contrast lines.
Conical Depth Scaling
Line width increases as the cutter plunges deeper along its ground V-angle, allowing CAM-controlled stroke thickness.
High-RPM Balance
Single-lip and half-round geometries are balanced for operation at elevated spindle speeds.
Clean Edge Formation
Sharp cutting lips peel away fine chips to support crisp, legible edges in soft and hard substrates.
Key Features and Benefits of Pointed Engraving Cutters
Fine Feature Resolution
Sharp-point geometry supports detailed micro-text and high-density vector graphics.
High-Speed Performance
Balanced profiles help limit chatter at spindle speeds of 20,000 RPM and above.
Clean Line Quality
Micro-ground cutting edges support sharp, readable line walls with less secondary deburring.
Multiple Included Angles
Standard configurations include 30°, 45°, 60°, and 90° profiles, with additional angles listed in the specification range.
Carbide Core Rigidity
Micro-grain carbide provides stiffness and helps retain point geometry during production use.

Materials and Coatings Available for Pointed Engraving Cutters
| Material / Coating | Best For | Key Advantage |
|---|---|---|
| Micro-Grain Carbide | Stainless steel, brass, aluminum, titanium, and plastics. | Provides point sharpness retention and rigidity during fine cutting passes. |
| TiAlN / AlTiN Coating | Hardened tool steels, stainless steel, and high-temperature alloys. | Helps protect the pointed tip from heat-related wear during dry engraving. |
| DLC / ZrN Coating | Aluminum, copper, acrylics, and brass. | Low friction helps reduce soft-material melting and welding at the micro-tip. |
Micro-grain carbide supports point rigidity, TiAlN or AlTiN helps manage heat in ferrous alloys, and DLC or ZrN reduces friction in non-ferrous materials and acrylics.

Frequently Asked Questions About Pointed Engraving Cutters
What is the difference between a sharp-pointed and flat-tip engraving cutter?
A sharp-pointed cutter terminates at a zero-radius point for very narrow lines and fine vector text. A micro-flat engraving cutter has a small flat at the tip, providing a stronger edge for wider lettering, background pocketing, and longer tool life in hard metals.
How do I choose the correct included angle?
Narrow angles from 10° to 30° suit deep, narrow engraving, micro-text, and circuit-board isolation traces. Broader 60° to 90° angles provide a stronger point for shallow surface marking, wider lettering, and small-hole chamfering.
What spindle speeds and depths are used for pointed engraving cutters?
The source recommends high spindle speeds, often 15,000 to 40,000+ RPM, with light axial depths around 0.002" to 0.010" and application-appropriate feed rates to reduce the risk of tip breakage.
Can pointed engraving cutters be used on plastic and acrylic?
Yes. Single-flute carbide cutters provide flute clearance that can help shear plastics, acrylics, and wood while limiting heat buildup and material smearing.
Does Bauron manufacture custom pointed engraving cutters?
Bauron can review custom V-angles, micro-flat dimensions, extended shank reach, and application-specific coatings for marking and production requirements.
