Onsrud 37-27 Engraving Cutter 30 Degree Solid Carbide

Product Description

The ONSRUD 37-27 is a solid carbide conical point engraving cutter designed for precision marking, lettering, and detail work on a variety of materials. It features a 30-degree included angle, a 0.03-inch cutter diameter, and a 0.03-inch tip diameter, making it well suited for fine-line engraving where dimensional accuracy matters. The single-flute geometry promotes clean chip evacuation and reduces heat buildup during cutting. With a 1/4-inch shank and a 2-inch overall length, it mounts directly into standard CNC router collets and engraving spindles. Installed by CNC machinists and routing technicians, this cutter is built to hold tight tolerances on production and prototype work alike.

The 37-27 is intended for use on aluminum, plastics, solid surface materials, and wood. It is a practical choice for sign-making shops, fabrication facilities, and cabinet shops running CNC routers or engraving machines. The uncoated solid carbide construction suits operations where consistent cut quality and cutter longevity on non-ferrous and composite substrates are the priority. Right-hand cutting direction makes it compatible with standard CNC spindle rotation.

Key Features

• 30-degree included angle conical point for fine-detail engraving passes
• 0.03-inch cutter diameter and 0.03-inch tip diameter for precise line width
• Single-flute design promotes efficient chip evacuation on non-ferrous and composite materials
• Solid carbide construction for rigidity and wear resistance
• Uncoated finish suitable for aluminum, plastics, solid surfaces, and wood
• Right-hand cutting direction for use with standard CNC spindle rotation

Compatibility

Part of the ONSRUD 37-20 series. Designed for use on aluminum, plastics, solid surface materials, and wood. Accepts a standard 1/4-inch collet on CNC routers and engraving machines.

Installation Notes

Installation is performed by a CNC machinist or routing technician. Power down and de-energize the spindle completely before changing tooling. Seat the 1/4-inch shank fully into the collet and torque the collet nut to the machine manufacturer's specification. Verify runout with a dial indicator before beginning a production run, as tip geometry at this diameter is sensitive to spindle concentricity.
