Trend TCT Counterbore

This Trend TCT Counterbore features a 3/4" (19.1mm) diameter cut with a 1/4" (6.35mm) shank diameter and a 3/4" cut length — the largest cutting diameter in the range, designed for recessing larger bolt and screw heads cleanly and accurately in plywood, particle boards, and abrasive plastics. The generous 3/4" cutting diameter makes this variant ideal for applications involving larger fixing hardware, such as coach bolts or substantial structural fastenings. The 1/4" shank ensures solid tool holding, while the fully adjustable design allows precise depth setting for a professional finish every time. For replacement twist drills, use slow spiral type — for example, 501/532 to 501/012. Not suitable for ferrous or non-ferrous metals.
