SDS Hammer Drill Bit

Close Up of drill shank is below.  Please make sure your drill uses SDS Plus bits.

1/2 inch and 3/8 inch SDS PLUS hammer drill bits for termite treatments.  Hammer drill bits are useful for drilling through concrete slabs when applying liquid termite control products. Drill holes should be placed 3 inches from the house and 10-12 inches apart. Once you have drilled the holes, use a pressurized sprayer to spray the termite chemical under the concrete slab.  Holes can be filled with with 1/2 inch Trebor plugs or 3/8 inch Trebor Plugs.

SDS plus SDS plus drill bits have 4 grooves (2 open grooves, 2 closed), and can be used in regular SDS drills or SDS plus drills. The reason that SDS plus drill bits have 4 grooves is to support to extra torque that the SDS plus drill provides. They have a 10mm shank which is inserted 40mm into the chuck. They can be used in SDS hammer drills up to around 4kg in weight.
