REAMERS
Purpose: Use a reamer to refine the size of a pre-drilled hole, accurate to ±0.0003 inches. Reamers can be used for press fit and slip fit holes. Read more from Chadwick Reamers
Tips for use: • Check the quality of the Reamer before and after use for damage, as it is a very precise tool. •For hole sizes less than ½ inch, drill 1/64 inch less than reamer size. • For hole sizes greater than ½ and less than 1 inch, drill 1/32 inch less than reamer size.• For holes greater than an inch in diameter, it is more accurate to use a boring tool than a reamer. •Ream at ½ of the Drilling RPM.•Use plenty of machine oil.•Ream with a steady, slow plunge rate.•Adjustable and taper reams are also available.
