Drilling is one of the most conventional types of machining operations to make holes. In this experimental work drilling has been performed on metallic (low alloy steel) and non metallic (bakelite) blocks by a radial drilling machine. At the exit side of the workpiece adhesive and wax were pasted to reduce the burr height and machining time. Experiment has been carried out in different rpm. It has been found that adhesive is very effective to reduce burr height for metallic specimen and machining time for non-metallic specimen. Wax is very effective to reduce machining time for metallic specimen and burr height of non metallic specimen.

Drilling is one of the most conventional types of machining operations to make holes. In this experimental work drilling has been performed on metallic (low alloy steel) and non metallic (bakelite) blocks by a radial drilling machine. At the exit side of the workpiece adhesive and wax were pasted to reduce the burr height and machining time. Experiment has been carried out in different rpm. It has been found that adhesive is very effective to reduce burr height for metallic specimen and machining time for non-metallic specimen. Wax is very effective to reduce machining time for metallic specimen and burr height of non metallic specimen.
