The fully ground spiral flute design helps clear chips efficiently to reduce friction and heat during drilling. Each bit features a 135° split point and straight shank to help prevent walking for more precise starts—often without needing a center punch (depending on your material and setup).
This set is suited for tough materials like stainless steel, steel, sheet metal, and cast iron, while also working on softer materials such as plastic, aluminum alloy, and wood. For best results, pay attention to drilling speed, pressure, and heat control—especially when working with hardened metals.
