Our coarse W183 unitized point measures 1/2" in diameter by 1/4" in length and is mounted on a 1/8" shank. They conform to workpieces for consistent, uniform finishing without undercutting or gouging. Unitized Mounted Points are constructed of pressed, non-woven tough abrasive nylon fibers, used primarily in finishing and surface preparation along with light deburring. These points are designed to provide long-life, are non-loading and will not unwind. They run smooth, which eliminates “chatter” marks sometimes created by bonded abrasives. Max RPM 51,700. Made in USA.
The durable unitized material is embedded with silicon carbide (for the fine grit) or aluminum oxide (for the medium and coarse grits).
· The silicon carbide is a fine/soft composition, requiring very little pressure. It is moderately conformably and provides high luster.
· The aluminum oxide with the medium composition requires heavy pressure and aggressive cutting.
· The aluminum oxide with the coarse composition requires the heaviest pressure and offers the most aggressive cutting including light deburring.
