TF Type Drills • High Metal Removal Rates

Kennametal's KenDrill™ TF (Three Fluted) solid carbide drills are engineered to perform at high metal removal rates across a diverse range of materials including cast iron, non-ferrous metals, and titanium alloys. With three cutting edges, these drills offer superior Metal Removal Rates (MRR). The drill’s open flute design ensures optimal chip evacuation, preventing interruption - and delivering better hole quality over two flute drills. Additionally, the TF solid carbide drills feature three-margin lands for maintaining a stable position throughout the entire drilling process. Kennametal’s full line of KenDrill™ TF is available in 5XD with straight shanks and with or without internal through coolant options.
