Ever needed a hole to be bigger in thick metal? Nothing says “step aside son I got this” like a Reamer Bit. OPT has traditionally stocked a full range of Maintenance Reamers that’ll fit into a ½” chuck and the big boys Bridge Reamers that fit into a hex socket (typically a 2” sockets) which means you’ll need a powerful impact wrench to them sing. Champion most recently launched their XSR Step Reamers with a nice XSR-SET that includes all 3 of the new Step Reamers.
So Why a Step Reamer?
Typically, a Reamer Bit is going to be a gradually increase in diameter which is a great tool for making something just fit. Make the hole a little larger, try the bolt again, doesn’t fit, make a little larger. It’s not a great tool for making a ½” hole into a ¾” exactly. These step bits allow for precision measurements and consistency for repetitive accuracy. Additionally, each diameter of the step is flat so you’ll get less rounding and slop in the hole, it will seem very much like it was drilled straight previously.

The Champion XSR Reamers and high quality bits designed for heavy duty applications up to ½” thick steel. Typical step bits are fine for sheet metal but really a totally different animal than these Step Reamers. Works off a 3/8” shank, will work with a heavy duty power drill or a mag drill, designed with duel flute for quick drilling, definitely requires lubrication to prolong the life of the bit.
