PLEASE SELECT A SIZE FROM THE DROP-DOWN MENU ABOVE Don't Use a Drill to Enlarge a Hole, Use a Reamer! Get the " Hole Story" with SA80 Reamers! Twist drills are designed exclusively to create new holes by cutting from the chisel point (center of the point) outward. This distributes the load evenly along the cutting lips. When a drill is used to ream, too much stress is focused at the outer cutting lips, resulting in chipped or broken drills. DRILLS vs. REAMERS SA80 chassis reamers, in contrast, don't chip because they are engineered only to enlarge holes. Their narrow point effortlessly fits into small holes, which enables the sides of the reamer to begin cutting. Cutting is quick and efficient because each reamer has five cutting edges to do the work. Performance is further enhanced by way of a 30 left hand helix, which safely disposes chips forward, away from user. The SA80's collar provides a safety stop by preventing over-penetration.
