The 7000 series of replaceable head reamers feature both expandable and fixed diameter heads. These reamers are ideal for high-production applications because the need to replace an entire reamer when it’s worn is eliminated. The replaceable reamer head can also be repaired to new condition, which extends the life of the investment. ALVAN reamers hold tight tolerances while improving the surface finish of the hole. Our expandable option accommodates for cutting edge wear.
