15-Piece Countersink Drill Bit Set

This NSI set supplies five countersink bits, five hex wrenches and five replaceable drill bits in a single orange case. It targets woodworkers who need adjustable depth control and quick bit changes for pilot holes, countersinking and counterboring in one operation.

Check drill compatibility and material limits

The bits use a round shank, so verify your drill chuck accepts that profile. The supplier states the set is not suitable for glass, metal, concrete or plasterboard, limiting use to wood, MDF and plastic.

Thermals noise and power draw in normal use

The steel and tungsten steel construction resists heat buildup during repeated drilling, keeping the cutting edges sharp. Operation remains smooth and quiet because the tool relies on the drill motor, adding no extra vibration or power demand.

Questions about this item

What does the 15-piece set contain and is anything else required to start using it?

The set includes five countersink drill bits sized 2.8 mm, 3 mm, 3.2 mm, 3.5 mm and 4 mm, five hex wrenches for adjustment and five replaceable drill bits. No extra items are needed to begin work.

Which of the five drill diameters should I choose for my project?

Pick the diameter that matches the screw shank you are using: 2.8 mm, 3 mm, 3.2 mm, 3.5 mm or 4 mm. Each size has its own countersink and replaceable bit in the kit.

What does the 10 mm counterbore diameter mean when the bit is in a drill?

It creates a 10 mm wide flat-bottomed recess around the pilot hole so a screw head sits flush or below the surface in wood, MDF or plastic.
