Die and mold production requires high quality finishing and severe cost reduction. So to determine the cutting condition is very significant. In this study, a simple estimating test of cutting performance for end milling is proposed. A pre-hardened steel was endmilled in side cutting method under thevarious cutting conditions. Surface roughness, cutting force and wear width aftter endmilling of 2.5m cutting length are investigated. Based on the results obtained. through the simple estimating test, wear test was conducted. Wear width on thecutting edges stayed within 0.1mm after endmilling of 100m cutting length.
