Truncated Tip Strength
Removing the pointed tip reinforces the cutting end for higher axial chip loads and feed rates than a comparable sharp point.

Tipped-Off Engraving Cutters
What Are Tipped-Off Engraving Cutters and How Do They Work?
Tipped-off engraving cutters combine a V-groove profile with a flat-bottom cutting geometry. A ground micro-flat removes the fragile zero-radius point and provides a stronger tip for repeated marking cycles.
Uniform Line Widths
The micro-flat forms a consistent flat-bottom groove width when cutting depth is controlled.
High-Speed Shearing
Precision-ground cutting lips shear material to create crisp wall transitions and clean line edges.
Vibration Control
Balanced single-flute and 2-flute profiles help limit runout at high spindle speeds.
Key Features and Benefits of Tipped-Off Engraving Cutters
Tip Durability
Truncated flat geometry reduces the point-chipping risk associated with sharp-pointed cutters.
Line Consistency
The defined tip flat helps maintain groove width when workpiece Z-height is controlled.
Clean Edge Finish
Micro-ground flutes support clean cuts in tough metals and can reduce manual deburring.
Multiple Included Angles
Available in 30°, 45°, 60°, and 90° V-profiles for different marking requirements.
Higher Production Feeds
The reinforced tip core supports higher feed rates and deeper passes than a comparable sharp-pointed geometry.

Materials and Coatings Available for Tipped-Off Engraving Cutters
| Material / Coating | Best For | Key Advantage |
|---|---|---|
| Micro-Grain Carbide | Stainless steel, brass, aluminum, titanium, and plastics. | Core hardness helps resist edge rounding and maintain the micro-flat geometry. |
| TiAlN / AlTiN Coating | Hardened tool steels, stainless steel, and high-temperature alloys. | Thermal stability helps protect the micro-flat tip from friction heat. |
| DLC / ZrN Coating | Aluminum, copper, acrylics, and non-ferrous alloys. | Low friction helps reduce galling and material welding at the cutting edge. |
Micro-grain carbide supports tip 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 Tipped-Off Engraving Cutters
What is the difference between a pointed and tipped-off engraving cutter?
A pointed cutter terminates at a zero-radius point for very narrow lines. A tipped-off cutter has a ground flat that reinforces the tip, supports higher feeds, and creates flat-bottomed characters.
How do I select the right tip-flat size?
Choose a smaller 0.005" to 0.010" flat for small text, fine line work, and compact serial numbers. Select a larger 0.020" to 0.030"+ flat for bold lettering, wider PCB isolation channels, or shallow background pockets.
How does a tipped-off design improve cutter precision?
Removing the fragile point helps the tool maintain a defined tip geometry through production. Stable tip geometry supports consistent character line widths and depth profiles when the process is properly controlled.
What spindle speeds are recommended for tipped-off engraving cutters?
The source lists spindle speeds from 15,000 to 35,000 RPM and notes that the reinforced flat supports higher feeds and deeper cuts than a sharp tip. Final parameters depend on the flat size, material, setup, and machine.
Does Bauron manufacture custom tipped-off engraving cutters?
Bauron can review custom included angles, micro-flat widths, extended shank reach, and application-specific TiAlN or DLC coatings.
