The Conical Ballnose Engraving Tool from 2L inc. offers dual functionality: It may be used for standard engraving projects as well as for 3D profiling and surface machining. According to the company, the tool can withstand higher cutting forces than standard ballnose endmills or tapered ballnose endmills. A 0.01"-radius conical ballnose engraving tool can withstand plunging 0.01" deep at 55,000 rpm and 300 ipm in aluminumÌýas it makesÌýat least 200 passes over the surface.

The tool’s strength makes it ideal for 3D-profile work in difficult-to-machine materials, the company says. Machining numerous passes at small depths of cut and high speeds yields products with fine surface finishes. The conical ballnose engraving tools are similar in style to the standard conical engraving tool, but with a radius tipÌýthat produces a cut with a rounded bottom.

The tools are available in shank diameters of ¹/₈", ¹¹/₆₄", ³/₁₆" and ¹/₄" with lengths varying from 2" to 6.5". The tip radius measures 0.005", 0.01" and 0.02" and included angles of 30 and 60 degrees.
