FIND YOUR CORE BIT

The thread is the whole game here: nearly every rig we sell is 1-1/4 inch UNC, and a bit on the wrong thread is a bit you cannot use. Start with what you are drilling with and the 61 bits, adapters and extensions narrow to the ones that will actually go on.

1 What does it screw onto? Read it off the machine spindle; adapters below bridge the rest

1-1/4 inch UNC Nearly every core rig in the range 1/2 inch GAS or BSP Handheld rigs; adapts to UNC SDS-plus Rotary hammer, not a core rig M14 Angle grinder M16 Paddle mixer thread Drill chuck Round shank, an ordinary drill

2 Bit, adapter or extension? A bit cuts, an adapter marries threads, an extension reaches deeper

Core bit The bit that cuts the hole

Thread adapter Marries a bit to a different spindle

Extension Drills deeper than the bit is long

Cutter or extra Cone cutters, pullers, drift keys

3 How big a hole? Bits only - adapters and extensions carry no bore size

Up to 32 mm Fixings, starter bars, resin anchors 35 to 82 mm Sockets, conduit, small services 92 to 152 mm Soil pipe, vents, ducting 162 mm and up Large cores, manholes, kerb

Diamond Core Drill Bits 4 products

Diamond core drill bits for reinforced concrete, granite and ceramic. Brands include ADTnS, Distar, Baumesser and Bycon, in sizes from 6 mm up to 500 mm. Wet bits suit reinforced concrete, and dry bits and SDS-plus socket bits are available too, along with ceramic and granite bits for tile and stone. Check the thread on your drill before you order: many bits use 1 1/4 inch UNC, and others are M16 or M14. Adapters to change thread, and extensions, are in Core Drilling Accessories. Need a hand choosing a bit for the material? Ring the counter on 01 889 9000.

The bit has to suit the motor as well as the material. For the motor, stand and wet or dry choice, read our guide to choosing a core drill.
