Universal tool has introduced carbide lugged reamers with special steel shank body. The carbide lugs are brazed and vacuumed with very strong brazing joint. Lugged design eliminates use of full solid carbide that saves the cost of tool. Lugged drills reamers are also supplied in coolant fed design where coolant channel is given in the body, offering very long life. These come from ø 8 mm up to ø 40 mm, also available with a variety of steps and combine designs. In case of solid carbide lugged design drills the special point filing geometry can be attained in making the drill self-centering, unlike in brazed design where this is not possible.
