Engraving Tool 37-21 Carbide 30 Deg
This Onsrud engraving tool is a carbide cutter with a 30-degree included angle and a 0.0050-inch tip diameter. It is supplied new and intended for precision engraving work where fine detail and clean lines are required. The uncoated carbide construction provides hardness for extended edge life in a variety of materials. This is a single cutting tool designed for use in compatible engraving systems.
Suited For Fine Detail Engraving Only
Machinists and engravers producing intricate markings, serial numbers or decorative patterns will find the narrow tip and sharp angle appropriate. This tool is not for heavy material removal, roughing operations or applications needing a larger tip radius. Buyers who need wider cuts, higher feed rates or tools compatible with coated-carbide requirements should look at other options. The Proposition 65 notice also applies for users in California.
Direct Tool Holder Installation
The tool installs by clamping the shank into a correctly sized collet or tool holder; no additional hardware is included. Ensure the holder runs true to avoid runout that can chip the fine carbide tip. Common issues include tip breakage from excessive feed rates, vibration from worn collets and premature wear if used on abrasive materials without coolant. Verify machine rigidity before starting.

Questions about this item
What CNC spindle or router accepts a 1/2 in shank for the Onsrud 37-21?
The Onsrud 37-21 has a 1/2 in shank, so it requires a CNC spindle or router with a matching 1/2 in collet or tool holder.
Can the 30-degree carbide tip replace an older high-speed-steel engraving bit in the same holder?
Yes, the 30-degree carbide tip fits any 1/2 in holder that previously held an HSS bit, giving longer edge life and sharper detail.
How do I confirm the 0.0050 in tip is cutting correctly after setup?
Run a test engraving on scrap material; a clean V-groove with a sharp 30-degree point and no chatter shows the 0.0050 in tip is working as intended.
