HSS Reamers
Benefits: Straight flute or spiral, taper pin or Check out bridge, Hertel™ HSS Reamers are the perfect Hertel™’s new line solution for enlarging or finishing an existing of HSS Reamers hole to a specific size and tolerance.
Chucking Reamers This is the most commonly used style for reaming holes to a tight tolerance. Chucking reamers are intended for use in drill presses, lathes and screw machines. Chucking Reamer Straight Flute, 45° Chamfer Angle • Pushes chips forward into hole • 45° angle provides easy hole entry • For use in blind or thru-hole applications Right Hand Spiral/Right Hand Cut (RHS/RHC) • Pulls chips out of existing holes • Design adds extra shear to finished hole • Ideal for blind-hole applications Left Hand Spiral/Right Hand Cut (LHS/RHC) Hand Reamer • Pushes chips forward into hole • Design provides the finest hole finish • Ideal for thru-hole applications Hand Reamers These have a square at the end of the shank, similar to a hand tap, which allows the user to turn the reamer with an adjustable wrench or a standard tap wrench. Hand reamers are constructed with a tapered cutting head to help the user push the tool into the workpiece. Straight Flute, 45° Chamfer Angle • 45° angle provides easy hole entry Bridge Reamer • Should be used in thru-hole applications only Left Hand Spiral • Pushes chips forward into hole • Design creates a better hole finish • Should be used in thru-hole applications only • Ideal for interrupted holes Bridge Reamers These reamers are designed to enlarge and align holes for rivets and are primarily used in steel construction involving I-beams. HSS Reamers
Taper Pin Reamers These reamers are designed to ream holes into which standard taper pins will fit, and feature a 1/4"-per-foot taper. • The straight flute and left-hand spiral are meant Taper Pin Reamer primarily for hand reaming • High-helix taper pin reamers are ideal for machine reaming—due to the construction of the high helix, left-hand spiral chips do not pack in the flutes
