• The carbide center pin ensures accurate hole starting without bit walk.
• The cutter with a peripheral thread enhances removal of dust.

• Plumbing work for installation of air conditioners, water, gas, electricity, etc.
• Dry drilling in block walls (reinforcing bars of up to ø 10mm (3/8") can be drilled at the same time), heavy-weight/finished concrete block, extrusion cement, mortar, and FRPM pipes.

• Use the "Drimond core bits" for dry drilling in reinforced concrete.
• Use the "Wetmond core bits" ( Wet type) to drill a hole in difficult-to-machine materials such as rigid tiles and large-diameter reinforcing bars (13mm (33/64") or larger).
• Use the center drill (PCHWCD250) for making a hole in hollow block etc. with the drill askew.
