Drill Bit Countersinks

Drill and countersinking combination products can cut a lot of work time and labour in half, giving an all-in-one single drilling and countersink tool and the optimal drilling experience. Our range of drill and countersink combo products feature TCT and HSS pilot drill components and an adjustable depth stop suitable for flush mounting and room for a plug. Drill and Countersink products can be ideal for a plethora of materials including timber decking, cement sheeting, woodworking and steel.

Most notably our specifically designed decking drill and countersink products are perfect for timber, hardwood and composite material decking as they have a free-spinning stop collar with a rubber o-ring which protects the work surface from marks and scratches. Other features include an anti-clog design which improves visibility and debris removal as well as an option between TCT, CRV and HSS Parabolic pilot drill bits.
