Onsrud 37-25 Engraving Cutter 30 Degree Solid Carbide

Product Description

The ONSRUD 37-25 is a solid carbide engraving cutter designed for precision detail work in CNC routing and engraving applications. It features a conical point geometry with a 30-degree included angle and a 0.02-inch tip diameter, making it well suited for fine line engraving, V-carving, and surface marking. The cutter measures 2 inches in overall length and mounts on a 1/4-inch shank. It runs in a right-hand cutting direction with a single flute, which helps clear chips efficiently at high spindle speeds. The uncoated solid carbide construction delivers the hardness and edge retention required for consistent, repeatable cuts on a range of materials.

This engraving cutter is used in CNC router and engraving machine setups across sign making, industrial marking, plastic fabrication, and woodworking. It is appropriate for both production shop environments and custom fabrication work where tight engraving detail is required. Compatible materials include aluminum, plastics, solid surface materials, and wood. The single-flute design keeps chip load manageable and reduces heat buildup during continuous engraving passes.

Key Features

• 30-degree included angle conical point for precise, clean engraving lines
• 0.02-inch tip diameter suited for fine detail and small character engraving
• Solid carbide construction for durability and consistent edge retention
• Single right-hand flute optimizes chip evacuation at high spindle speeds
• 1/4-inch shank fits standard CNC router collets
• Uncoated finish compatible with aluminum, plastics, solid surfaces, and wood

Compatibility

Part of the ONSRUD 37-20 series. Designed for use on aluminum, plastics, solid surface materials, and wood in CNC routing and engraving equipment accepting a 1/4-inch shank.

Installation Notes

Installation is performed by CNC machine operators or machinists. Power down and lock out the spindle before changing tooling. Seat the shank fully into a clean, properly sized collet and torque the collet nut according to the machine manufacturer's specification. Inspect the tip for chipping before each use, as carbide engraving tips are brittle and sensitive to impact.
