• The DDU★★★ bond is specifically designed for drilling into New Zealand fibreboard & cladding, masonry & brick and concrete
• It is a quick and easy solution for coring holes with conventional rotary drill motor (over 1kW)
• ½" female back-end
• Usable length (L2): 150 mm

Kit includes:

• 3 pcs dry core drill bits: 38 mm, 52 mm and 65 mm
• Machine adaptors: SDS+ (short and long), hex (short and long), drift key and masonry pilot drill
• 2 empty sections in the case are for optional extra core bits which can be purchased separately

• Use a conventional rotary drill motor (over 1kW) and a speed range of 1,000-3,000 rpm. Do not use with hammer action.
• For optimal result, insert pilot rod after drilling pilot hole with masonry drill bit. This prevents the core drill bit from moving when starting to drill, ensures a cleaner hole and a longer drill bit lifetime. It will also make the operation safer and reduce physical stress.
