Trend Countersink Drill Bit - TCT - 1/4"" Hex Shank

The Tungsten Carbide Tipped (TCT) cutting tips provide exceptional durability and a longer service life, especially when working with abrasive wood-based materials like laminated chipboard and MDF.

No, this drill bit is designed to produce pilot holes only, which are smaller holes that guide the screw. It does not create clearance holes, which are larger holes that allow a screw to pass through without engaging the threads.

Loosen the small locking screw on the side of the bit holder, slide the HSS piloting drill in or out to your desired position, and then firmly retighten the locking screw.

It is designed for No. 10 Imperial screws in softwood and No. 8 screws in hardwood. The HSS pilot drill can be adjusted to suit different timber thicknesses.

Yes, the 1/4"" hex shank is compatible with standard chucks found on both drills and impact drivers. However, using lower speed settings is generally recommended for better control and finish.

Countersinking creates a conical-shaped recess at the top of a pilot hole, allowing a screw head to sit flush with or below the surface. Counterboring creates a cylindrical recess, useful for larger screw heads or for concealing fixings with plugs.

Keep the bit clean by removing wood dust and debris after use. Store it in a dry environment to prevent corrosion on the HSS drill. Avoid using it on inappropriate materials like metal or concrete.

Ensure the 1/4"" hex shank is fully inserted and securely tightened in the drill chuck. Check that the chuck is clean and free of debris.

Re-adjust the HSS piloting drill depth. Ensure the locking screw is fully tightened after adjustment. Verify the selected screw size and corresponding timber type match the tool's specifications.

The tool may be used in overly abrasive material or beyond its intended use. While TCT tips are durable, they can wear or chip. Ensure you are not drilling into non-wood materials. Clean the bit thoroughly.
