Burghiu individual KWB 512006 6 mm hexagonal

The KWB 512006 Drill Bit Single is a 6 mm HSS-M2 bit with a 1/4" (E 6.3) hexagon shank designed for accurate pre-drilling in hardwoods such as Bangkirai, as well as softwoods. It combines a drill, adjustable counterbore and countersink in one tool and provides consistent bore and countersink depth when installing decking or garden furniture fastenings.

Advantages

The high-speed steel (HSS-M2) construction offers good wear resistance for wood drilling. An adjustable counterbore with a ball-bearing stop prevents the counterbore from rotating when it contacts the workpiece, avoiding marks on the wood surface. The 1/4" hexagon shank to ISO 1173, E 6.3 ensures secure fitting in impact drivers and quick-change chucks. Compact 6 mm diameter allows precise pre-drilling for screws and fixings in hardwood and softwood.

How to use

Mount the 1/4" hexagon shank securely in a compatible driver or drill chuck. Adjust the counterbore depth to the required setting for the screw head, then tighten the depth stop. Position the bit on the marked drilling point and drill at a steady speed suitable for the wood species. The ball-bearing stop will engage when the counterbore reaches the surface to prevent rotation and marking.

Recommendations

Use light to moderate feed pressure and appropriate drilling speed for hardwoods to avoid overheating. Check the depth stop setting on a scrap piece of the same wood before final holes. Store the bit dry and protect the cutting edges to maintain performance.
