Engraving Flat, Curved and Uneven Surfaces:
- Spring loaded design compensates for uneven or curved material surfaces.
- .40″ of travel to the Tool Bit compensates for variations in the material surface and varying part height.
- Constant pressure is applied to the engraving tool bit as it moves over the surface being engraved.
- Tool bit floats back and forth within the Tool Holder to move over inconsistencies in the part.
- Slight surface variations from part to part no longer create illegible engraving.
- It is not critical that the part being engraved is perfectly flat on the machine table.
Engrave Using A CNC Machine:
- Use the CNC milling equipment you already have for marking and engraving parts.
- Machine and Engrave using the same machine.
- No need for dedicated engraving machines or marking systems.
- No need to move a part from one machine to another to engrave on a separate machine.
Reduce Set Up and Engraving Cycle Times Up To 84%:
- Dramatically reduce engraving cycle times up to 84% by Rapid Tool (G0) into the part and correct use of our suggested increased feed rates (instead of slow feed).
- Set up times can be significantly reduced in production applications.
- As the Spring Loaded Engraving Tool compensates for height variations from part to part, there is no need to relocate each part when loaded into the CNC machine.
- Spring action creates a consistent depth of engraving across workpieces with height variations, eliminating the need to repeat engraving on low spots where engraving may have been missed with typical rigid tool engraving.
Improve Tool Bit Life:
- The spring loaded design allows the tool bit to float with the contour of the part.
- Possible breakage or wear is minimized when engraving inconsistent materials and workpieces.
- As the spring expands and contracts with varying material surfaces, high spots on workpieces are compensated for, improving tool life.
- The 3/4″ diameter and 20 mm diameter Spring Loaded Engraving Tools can be held in a Collet or End Mill Holder.
- Rotary engrave practically any material using a Spring Loaded Engraving Tool with Solid Carbide Engraving Tools.
- 2L Engraving Tool Bits are produced in many different styles, angles and tip widths which create a range of depths and widths of engraved letters, lines, logos and serial numbers.
2L Solid Carbide Engraving Tools can be used in a Spring Loaded Engraving Tool, as well as rigid tool holders.
If you are looking for longer tool life:
- Tough Tip Engraving Tool for Steels & Stainless Steel.
- Tough Tip Engraving Tool for Aluminum.
If you are looking for extremely clean engraving and greater depth of cut when using a Spring Loaded Engraving Tool:
- Standard Conical for Hard materials.
- Standard Conical for Soft Materials (recommended for Plastics).

with a Heavy Spring.
Which Spring to Use:
- Springs provide force against the tool bit.
- Stronger Springs apply greater force to the Tool Bit tip. Additional force affects depth of cut and tool life.
- A Light Tension Spring is included with each Spring Loaded Engraving Tool and is typically used for general engraving of Plastic, Brass, Aluminum, and mild Steels.
- An Extra Light Spring can be used to apply less force when engraving very soft Plastics.
- A Medium, Heavy, Extra-Heavy, or Extra-Extra Heavy Spring can be used to obtain greater depth of cut on Steels, Stainless Steel, Tool Steels, and many other hard materials.
Feel free to contact us for assistance in Spring selection for your application.
- Each 3/4″ diameter and 20 mm diameter Spring Loaded Engraving Tool Kit includes a 3/16″ integrated Collet.
- The 3/16″ Collet holds 3/16″ diameter Engraving Tools in the Spring Loaded Tool.
- Additional Collets are available to hold other diameter tools.
- 1/8″, 1/4″, 4 mm and 6 mm Collets are available separately.
Letter Height and Engraving Depth:
- Typical engraving of text height of 10 pts. (.085″) and larger is possible using a wide variety of standard engraving tool styles and sizes.
- When engraving letters with height of .125″ and smaller using a Spring Loaded Engraving Tool, we recommend an Engraving Tool with 60 degree angle and .010″ or .015″ tip width.
- When engraving letters larger than .125″, we recommend a 60 degree angle and tip widths of .020″ and greater.
- Engraving letters as small as .030″ high is possible using a Spring Loaded Engraving Tool with a 90 degree Carbide Point Engraving Tool and a Heavy Tension Spring.
- Typical depths of engraving that can be attained range from .002″ – .015″ per pass.
- Depth of engraving that can be attained varies and is dependent on the hardness of the material being engraved, strength of the Spring used, Engraving Tool Bit Style, and speeds and feeds.
- 2L produces many style and size Engraving Tool Bits for practically any application and material.
Feel free to contact us for assistance in selecting the optimum Engraving Tool Bit for your application.
When Precise Engraving Depth is Required:
- If exact engraving depth is required, use the optional Depth Control Engraving System.
- Depth Control Engraving system can control engraving depth in 0.001″ increments.
- The Nosepiece System is typically used and very effective when engraving very soft materials such as Plastics when using a Spring Loaded Engraving Tool.
Polish, Buff and Deburr:
- Use brushes and polishing wheels to polish, buff and deburr workpieces.
