Our 117mm diamond core drills have been manufactured to a high standard to withstand the huge stresses involved when core drilling into general masonry building materials. Our diamond core drill bits offer excellent drilling speeds and lifetime when used with most core drill machines due to their high diamond concentration, high quality barrels, back ends and 10mm segment height.
Our 4.5 inch core drill bits are supplied as standard with a ½” BSP female back end and can be fitted with either a 13mm hex adaptor to fit a standard 13mm 3 jaw chuck or can be fitted with a SDS plus adaptor to fit an SDS core drill.
Our 4.5 inch core drills are recommended to be used in conjunction with a diamond core drill machine that is fitted with a slipping clutch and a minimum 850 watt motor to ensure fast drilling characteristics when drilling concrete, brick and masonry products.
