Trend Professional TCT Counter Bore Set, 3/8 Inch Counterbore with 3/16 HSS Slow Spiral Drill Bit, Tungsten Carbide Tipped, CB38 316TC

The Trend CB38-316TC is a tungsten carbide tipped counterbore with an attached HSS slow spiral drill bit, designed for recessed bolt and screw heads in wood and wood-based materials. It offers a 3/8 inch counterbore diameter and a 3/16 inch drill diameter, and includes a hex-key for adjusting drill length to accommodate different screw lengths. The bit is suitable for plywood, particle board, and plastics, and is intended to create clean recesses that allow bolt and screw heads to sit below the surface, finishing with matching plugs for a seamless look. It is optimized for hardwoods and applications requiring clear finishes when filled with plugs. Use only at drilling speeds and ensure proper alignment of flutes during setup to achieve accurate depth and alignment.
