Coolant Fed Twist Drills are used in drilling machines which feed coolant directly to the cutting edge during operation, reducing temperatures and flushing chips out of the hole for faster work, longer tool life and reduced downtime. Taper shank models have dual coolant entry in the tang end and the side of the taper, while straight shank models are used in appropriate coolant-fed toolholders. Large holes at the point end improve coolant flow to the workpiece for decreased friction and better chip removal. Suitable for a variety of stainless steels, cast iron, and other ferrous and non-ferrous metals and alloys. For best results when drilling under 3/8" diameter, use a drill bushing or pilot hole of the same dimension. «Less

Annular Cutters are also known as hollow drills, and are typically used to create larger holes than regular twist drills in pipe and tubing, conduit work & sheet metal fabrications. Annular cutters are typically used with a drill press, but can also be used with a twist drill. They last longer than twist drills because they only cut around the perimeter of the hole, leaving a solid core behind (similar to a hole saw). Annular cutters have spiral flutes along the outer edge for easier chip removal, longer wear and up to three times faster work than hole saws. Portable magnetic drill press annular cutter sets provide powerful and ergonomic drilling solutions in confined areas. «Less
