Semi finished reamers are furnished with a potential cutting diameter above the largest diameter indicated in the size range. Before semi-finished reamers can be used, the cutting diameter must be finish ground and relieved and the reamer’s end must be faced and chamfered. Semi-finished reamers are purchased by regrind shops or distributors and users with regrind facilities. For more detailed descriptions please see the matching list number under Reamers in the blue to the left on the main page.
