MAPAL Twin-Bladed Reamers with Guide Pads

Twin-bladed reamers allow the cutting speeds and feed rates to be increased compared with single-bladed reamers with guide pads. The inserts are installed and adjusted so that they are staggered radially and axially.

Key Features

• Twin-bladed reamers allow the cutting speeds and feed rates to be increased compared with single-bladed reamers with guide pads.
• The inserts are installed and adjusted so that they are staggered radially and axially.
• Dividing the cutting depth into a premachining and finishing cut with only a few hundredths of a millimetre chip thickness ensures very good surface finishes and long tool lives, even in materials that are difficult to machine.
• Based on this principle, MAPAL also offers multi-cutting edge adjustable tools with guide pads designed, for example, according to the 4+2 principle, i.e.
• with four leading inserts and two finishing inserts for even higher feed rates.
