Onsrud 37-25 carbide engraving tool
The Onsrud 37-25 is a carbide engraving tool with a 30 degree angle and a .020 inch tip. It is sold new and comes uncoated for use in precision marking or detail work. The tool is listed under hole, drill, bore and wire gauges by the manufacturer. It is intended for operators who need a single, small-diameter engraving point.
Suited for fine detail engraving
This tool suits users engraving fine lines or marking small features where a .020 inch tip at 30 degrees is required. It is not for buyers who need a larger tip diameter, a different included angle, or a coated cutting surface for extended wear. It also does not serve applications requiring multi-flute or indexable insert configurations.
.020 inch tip diameter at 30 degrees
The decisive specification is the .020 inch tip diameter combined with a 30 degree included angle. That geometry determines the minimum feature width and the depth-to-width ratio achievable in a single pass. If the job calls for a different tip size or angle, this tool will not produce the correct result.

Questions about this item
How often will the 0.020 in carbide tip need replacing?
The uncoated carbide tip wears gradually; replace it when the 30-degree point no longer cuts cleanly or shows visible rounding.
What limits continuous engraving with this 30-degree tool?
Heat buildup in the carbide tip is the first limit; pause periodically to let it cool and maintain the 0.020 in edge.
Does the 1/2 in shank get hot during all-day use?
The shank stays near ambient temperature because cutting heat concentrates in the small carbide tip rather than the steel body.
