Construction Reamers

OEM Tool left-hand spiral flute construction reamer is a round shank tool made of high-speed steel with no finish or coating, and is most commonly chosen for reaming interrupted cuts in structural steel. Construction reamers are tapered to allow the reamer to enter overlapping and misaligned holes where extremely precise tolerances are not necessary, and have a stop collar for safety and depth control. Left-hand spiral reamers are useful for interrupted cuts and in through holes. Spiral reamers prevent whole flute contact with the leading edge in an interrupted cut, as in a keyway. This prevents damage to the interruption and reamer flute. Left-hand spiral style tools also push chips ahead of the tip of the tool, instead of pulling chips out of a hole. Left-hand spiral reamers are also useful when reaming through holes, since pushing chips into the hole can cause clogging, which may damage the tool. High-speed steel is a general purpose steel for cutting tools and is compatible with many metalworking materials. It is often lower in price than other cutting tool materials. There are five flutes for all reamers we stock. Tolerances are +0.005 -0.000 inches. All shanks are tri-cut for increased holding strength.
