Modular Drills

Kennametal modular drills combine the high feed rates and length-to-diameter capabilities of solid carbide drills with the high speed and low consumable costs of indexable drills. The drill bodies accept a range of insert sizes, allowing for quick tool set-up to help to reduce inventory. Kennametal’s market-leading portfolio of modular drills offers both versatile and material-specific tools for all industries. Select from KenTip™ FS for small holes, KSEM™ for medium-sized hole diameters, or KSEM Plus™ for larger diameter holes.
