Flat Bottom Drills • Flat-Bottom Applications
Flat bottom drills with through coolant offer precision and efficiency in holemaking operations. They excel in creating flat-bottom holes with accuracy and consistency across multiple workpiece materials. Kennametal drills are available in FBS for non-ferrous materials, FBG for steel and cast iron, and FBL for stainless steel and high-temperature alloys. These drilling tools feature a unique design with two effective cutting edges over the center, enabling high feed rates and optimal performance. Additionally, these application-specific solid carbide drills integrate two operations into one --removing the need for a 180° end mill in flat-bottom drilling or for preparing inclined or curved surfaces for drilling. This innovative approach streamlines the process, saving time and enhancing productivity. With the ability to create true flat-bottom holes from the outer diameter to the center, these drills are reliable solutions for your holemaking needs.
